main.jsbundle does not exist. This must be a bug with + echo 'React Native

[hanishsharma]

Hello team,

I am getting this error while running my xcode project.

main.jsbundle does not exist. This must be a bug with + echo 'React Native.

Please help.

Thanks.

[IbraheemAlSaady]

This happens when there is no offline bundle file in your project, I had the same problem and this worked for me.

If you're running on the device, check the Running On Device docs

I added the below to my package.json file so I don't have to type it every time I want to generate an offline bundle

"build:ios": "react-native bundle --entry-file='index.ios.js' --bundle-output='./ios/YourAppName/main.jsbundle' --dev=false --platform='ios' --assets-dest='./ios'"

And you can run it like this npm run build:ios

You'll see the main.jsbundle file generated inside your ios/YourAppName directory

Next, open your project using XCode, right click on your project name then click Add Files to "YourProjectName", choose the main.jsbundle file that was generated, and then build again.

That should do it.

I'm using

"react": "16.0.0-alpha.12",
"react-native": "0.46.1",

[scottyantipa]

Not sure if this is the answer, but this issue went away for me when I moved my type declaration packages from devDependencies to dependencies in package.json.

The packages were @types/react, @types/react-native, @types/react-navigation.

[lolobosse]

@scottyantipa Can you elaborate on that? What packages? and what type declaration? That would help me a lot! 😄

[scottyantipa]

@lolobosse I updated my comment above

[lolobosse]

@scottyantipa I found my error, it was a weird \ in a string.

I had to debug the bundler and I saw the file crashing.

@ReactNative Team: that would be great that if the --verbose option is activated, you deliver more logs than just SyntaxError on the bundler 😄

[cconstable]

For this issue was caused because the index.ios.js file was not located in the root directory of the repo. I had to modify the Build Phases -> Bundle React Native code and images script in Xcode to point it to the correct directory.

Original (what react native generated):

export NODE_BINARY=node
../node_modules/react-native/scripts/react-native-xcode.sh

Fixed:

export NODE_BINARY=node
../node_modules/react-native/scripts/react-native-xcode.sh ./src/index.ios.js

[xavieramoros]

I had a similar error after doing a pull of a repo upgraded to 0.48.4 (someone else did the RN upgrading).

Doing rm -rf ./node_modules && npm install showed this error, but doing: rm -rf ./node_modules && yarn actually fixed it. So I guess there are subtle differences on how yarn and git handle install scripts.

[johndanek]

@lolobosse What string was the / in? React Native code, or somewhere in XCode?

[jpapillon]

@johndanek The node_modules directory is always at the root of your project (React Native code).

[JamesDorrian]

Tried all of above, problem still persisting. Why was this closed @hanishsharma ?

[YasirSherzad]

Hi , I am using react-native 0.49, I get this error on device only , it works fine on Simulator. I tried many things but none worked.

[JamesDorrian]

@hanishsharma Why did you close this?

[MoOx]

I just got this, and that was just that the bundle wasn't building correctly.

I started dev mode and found an fatal error that were blocking compilation (a bad require). It was that simple.

[jordanmkoncz]

I had this issue as well when I tried to create an archive in Xcode.

For me, it was because the command to build the JS bundle was failing, and the reason it was failing was because one of my dependencies had a specific babel preset in its .babelrc file, which I did not have installed in my main React Native project's package.json.

In the Xcode error output, a few lines above the "main.jsbundle does not exist" line, I had the following error message from the react-native bundle command that had run:

TransformError: /Users/jordan/Development/MyAppName/node_modules/dotenv-parse-variables/lib/index.js: Unknown plugin "add-module-exports" specified in "/Users/jordan/Development/MyAppName/node_modules/dotenv-parse-variables/.babelrc" at 0, attempted to resolve relative to "/Users/jordan/Development/MyAppName/node_modules/dotenv-parse-variables"

So I installed the missing plugin by running: yarn add --dev babel-plugin-add-module-exports

I then went to Xcode again, did a Product -> Clean, then Product -> Archive, and this time it worked.

I actually used to have these dependency-related babel plugins installed, but I removed them because the release notes for 0.50.0 (https://github.com/facebook/react-native/releases/tag/v0.50.0) stated that this wouldn't be required anymore due to the change in enableBabelRCLookup. But I guess that change isn't quite working correctly, so for now we'll have to keep using the workaround I used here, or the postinstall workaround that they describe in those release notes.

For reference, here's my dependencies:

"react": "16.0.0",
"react-native": "0.50.3"

[unmec]

Just to share something that I've found out about this issue.

• I can build for debug, but when build for release, RN throws the error

• Clean different sorts of cache / reinstall node npm / change xcode settings etc have nothing to do with my issue

• A clean new project with react-native init has exactly the same issue

• Sometimes it's caused by typos, you can build for debug to see if its caused by typos. If debug build succeeds, then your js files are all OK

• If you have checked all above items and still face the issue, finally, it's probably due to your network environment. When you develop on some internal networks that have atypical settings of firewall, you might face this issue. Just disable your wifi network on you Mac, then build for release on your phone / simulator, it should run as expected.

Took me some good 2 hours to find it out.

[viethaca]

i have same problem, i use "react": "16.0.0-alpha.12" "react-native": "0.48.4" i change in "node_modules/react-native/scripts/react-native-xcode.sh" ENTRY_FILE=${1:-index.ios.js} to ENTRY_FILE=${1:-index.js}

[asleepace]

The problem for me had to do with Apple's iCloud syncing my desktop and documents. For me the fix was moving the folder to a directory that wasn't synced with icloud in my ~ directory. I cloned the repo from git and stopped having these issues. Hope this helps someone, lost two days on this...

[dwilt]

The key here is to look in Xcode, above the "main.jsbundle does not exist" message and see what the actual reason for the bundle not being created is:

In my case, the actual error (TransformError: /Users/dwilt/Documents/GitHub/the-resistance/firebaseFunctions/gameStructure.js: Cannot read property 'useBuiltIns' of undefined) was caused from the release build failing to import a file from outside my src directory - but only when building for release. Not sure why yet but moving the file to the src directory solved it.

[saqbach]

Not sure if I'm doing this correctly but I had this issue when trying to run react-native run-ios after following the steps for running on device and getting the app ready for publishing to the app store.

I removed the following to enable App Transport Security:

<key>NSAppTransportSecurity</key>
  <dict>
    <key>NSExceptionDomains</key>
    <dict>
      <key>localhost</key>
      <dict>
        <key>NSExceptionAllowsInsecureHTTPLoads</key>
        <true/>
      </dict>
    </dict>
  </dict>

However, if I don't add it back in to my Info.plist when I want to debug, then I get the main.jsbundle missing error.

[petarivanovv9]

Hello guys! I tried everything that I read through github issues and google but I can't still find the solution for me. When I'm using the simulator everything is fine but when I try to make an archive or build it on my phone I have this error:

File /Users/.../Library/Developer/Xcode/DerivedData/<app_name>-cyixycawuftgogfcezlrqhtzvdyo/Build/Intermediates.noindex/ArchiveIntermediates/<app_name>/BuildProductsPath/Release-iphoneos/<app_name>.app/main.jsbundle does not exist

My dependencies are:

"react": "16.0.0",
"react-native": "0.50.3",

I will be very happy if anyone could help me because I am stuck with this issue from 2 days and I can't submit my app for test flight.

[npalethorpe]

Just had this issue myself, turns out it was caused due to a space in one of my higher up folder names. I removed the space from the name and it sprang into life!

[HermitCarb]

Find another case: Wrong case in file name。

The actual filename is UMPush.js, I thought it was UmPush.js, and git ignored it. (I changed the char case of file name and forgot git.😔)

[treyp]

Looks like the issue with spaces in the CLI path was fixed in #17628.

[jsdario]

Hi, is there any difference in using unbundle as BUNDLE_COMMAND? https://facebook.github.io/react-native/docs/performance.html#unbundling-inline-requires

I am experiencing the following issue: https://stackoverflow.com/questions/48751053/react-native-unbundle-app-gets-hung-in-release

[xeieshan]

@cconstable @IbraheemAlSaady

Both your solutions didn’t work for me

"build:ios": "react-native bundle --entry-file='index.ios.js' --bundle-output='./ios/YourAppName/main.jsbundle' --dev=false --platform='ios' --assets-dest='./ios'"

&

export NODE_BINARY=node ../node_modules/react-native/scripts/react-native-xcode.sh ./src/index.ios.js

[Loxrie]

@xeieshan

It seems to have worked for me, I had to add the file into xcode and add it into the "Build Phases"->"Copy Bundle Resources" in the target.

Assuming you've modified AppDelegate.m to load the resource instead of using RCTBundleURLProvider:

jsCodeLocation = [[NSBundle mainBundle] URLForResource:@"main" withExtension:@"jsbundle"];

[WoodyWoodsta]

Ran into this issue today and it turns out that invoking the build via a yarn script was the culprit. Using npm run or just the raw commandline worked fine for me!

[miguelacio]

i did what IbraheemAlSaady told us to do and my app is having a a really weird behavior, it change all my aplications images/icons to theios/ folder, I dont know why or how this happened, please help my boss is gonna fire me

[isAlmogK]

I'm having a similar issue has anyone had this issue before - https://stackoverflow.com/questions/49313917/react-native-app-can-build-for-debugging-but-not-for-archiving

[Stas-Buzunko]

got this error when library was added but forgot to run npm i / yarn npm i fixed it

[matteocollina]

This is my script : Create jsbundle and import to XCode. NB: I've integrated React-Native into an existing native app, so my RN code in into /js folder.

https://gist.github.com/matteocollina/ee92ee698ddfefceb8ce85c9d94d69df

if [ "$CONFIGURATION" == "Debug" ]; then
  echo "Debug Configuration"
else
  echo "Release Configuration"
  cd js
  react-native bundle --platform ios --dev false --entry-file index.ios.js --bundle-output main.jsbundle
  RESOURCE_PATH=$SRCROOT/js
  FILENAME_IN_BUNDLE=main.jsbundle
  BUILD_APP_DIR=${BUILT_PRODUCTS_DIR}/${PRODUCT_NAME}.app
  cp $RESOURCE_PATH/$FILENAME_IN_BUNDLE $BUILD_APP_DIR/$FILENAME_IN_BUNDLE
  echo "Copied jsbundle √"
fi

[LivioGama]

None of everything above worked for me. I had to change .babelrc file to :

{
  "presets": ["react-native"],
  "plugins": ["transform-decorators-legacy"],
  "sourceMaps": true
}

[thegamenicorus]

For me, it's because of remove some packages (via npm uninstall/yarn remove) but still have references in Xcode project.

The solution is goto Build Settings, then remove node_modules reference of deleted packages in "Framework Search Path" and "Header Search Paths".

Hope it help someone here.

[futurechallenger]

Look above of the error, you will fine what exactly wrong when the shell script trying to package your js file. My problem is that I missed a , in an object definition!

[jbcrestot]

Like many people, I came across this topic when I had the same mistake, which is why I want to share what really caused the problem : Context : We(@kisioDigitial) build our apps through jenkins which use fastlane (for release purpose), we didn't had any problem till 1 month but during this month we upgrade our react-native version from : { "react": "16.0.0-alpha.6", "react-native": "^0.44.0" } to { "react": "^16.2.0", "react-native": "^0.52.2"}

It turns out that it's the same problem that npalethorpe got (https://github.com/facebook/react-native/issues/15432#issuecomment-359789055), Jenkins create directory workspace according to the build name which in our case had several spaces.

I'm not 100% sure that issue come from the react-native upgrade, but removing the space from the build name (so from the directory name) resolve the issue and build no longer fail on the main.jsbundle missing file

[enieber]

this occurred when I had a problem in directory js modules

[dzpt]

@IbraheemAlSaady

npm run build:ios
npm ERR! missing script: build:ios

got this error after execute command

[small3flower]

Useing Xcode to open the iOS project will solve this problem.

[xyz150462]

I find an easy way to solve it . you just run your project using simulator while not your Device at the first time. After you do it, it will have a local main.jsbundle file automatically and then you can run it on your Device success. it works for me, hope so with you.

[noahtallen]

I'm getting the issue when doing CD builds on Bitrise using the Xcode archive and export step. Here's the last bit of the log:

▸ Running script 'Bundle React Native code and images'
    the transform cache was reset.

❌  error: File /Users/vagrant/Library/Developer/Xcode/DerivedData/zonder-dfxxvabfiixsrgbdsqgwkghxwehd/Build/Intermediates.noindex/ArchiveIntermediates/zonder/BuildProductsPath/Release-iphoneos/zonder.app/main.jsbundle does not exist. This must be a bug with React Native, please report it here: https://github.com/facebook/react-native/issues'

I'm confused because the build has been working very well for us for quite some time, and it just started failing. Additionally, I can't reproduce the issue locally via normal debug builds or via a local Xcode archive in release mode. Any thoughts on what I should look into next? I'm thinking about trying to nuke the node_modules cache for yarn first.

[deehuey]

Thanks @futurechallenger , actual error was above the highlighted error!

[luolin2611]

@gfly 你搞定这个问题了？

[tibbus]

For me it works on my local machine but it fails on the bitrise build, locally works with node 8 and 10 but on bitrise works only with node 8 (only with yarn)

[ahaus]

I got the error "main.jsbundle does not exist" when I upgraded from 0.46.4 to 0.47. What helped in my case was to add or rename index.ios.js to just index.js. After this it worked fine.

[nadbm]

For me, the build process was using an old version of node. I had it installed via nvm so modified the following (in Build Phases > Bundle React Native code)

export NODE_BINARY=node
../node_modules/react-native/scripts/react-native-xcode.sh

to

export NODE_BINARY=/Users/nadim54321/.nvm/versions/node/v10.3.0/bin/node
../node_modules/react-native/scripts/react-native-xcode.sh

[ashokseervidev]

react-native bundle --entry-file ./index.ios.js --platform ios --bundle-output ios/main.jsbundle

Run this command it should work.
