npx aborting creation

[akctba]

The npx command is aborting and doesn't create the application.

I'm using the command: npx create-react-app appexample

and at the end of the execution it prints:

Error [ERR_INVALID_PACKAGE_TARGET]: Invalid "exports" main target "index.js" defined in the package config /Users/alexkayser/git/apptest/node_modules/is-promise/package.json at resolveExportsTarget (internal/modules/cjs/loader.js:542:13) at resolveExportsTarget (internal/modules/cjs/loader.js:581:20) at applyExports (internal/modules/cjs/loader.js:455:14) at resolveExports (internal/modules/cjs/loader.js:508:23) at Function.Module._findPath (internal/modules/cjs/loader.js:632:31) at Function.Module._resolveFilename (internal/modules/cjs/loader.js:1001:27) at Function.Module._load (internal/modules/cjs/loader.js:884:27) at Module.require (internal/modules/cjs/loader.js:1074:19) at require (internal/modules/cjs/helpers.js:72:18) at Object.

Same here - good to know that others are having the problem as well. Thought I somehow screwed up my node installation 😱

Edit: I also tried globally installed create-react-app, same issue there.

Tried with 12.4, 12.6 and 14.0.0. Same problem here on Windows 10 last version (1903).

[whoisdominic]

Same

[minrelp]

if you just want to create react app, you can do this while waiting for a fix: step 1: yarn init -y

step 2: Insert this to package.json

"resolutions": {
    "is-promise": "2.1.0",
    "run-async/is-promise": "2.1.0"
  }

step 3: yarn add --dev create-react-app

step 4: yarn create-react-app ../my-app

[MarkarianFR]

I’m not sure this scheme is the most beneficial.

[juliocorcini]

Same Error Installing Firebase.

Just Wait?

[SylCard]

so its not me going cray this happening rn lol

[hotkebab99]

Same for me with Node 12.16.1

[nemethmik]

I downgraded Node to 12.12.0 and everything works fine, so Node has been screwed up recently

[vibiu]

same for me, and create umi failed. node: v13.13.0 npm:6.14.4

[MarkarianFR]

Node version > 12.12 is completly done about react Nice x)

[ssrome]

Glad I'm not the only one. Was able to create one a few hours ago. Tried again a few minutes ago and had the same error. Using Node v13.11.0

[Parsijn]

Same here when trying to create a vue/cli app node: 14.0.0 npm: 6.14.4

[rvalenta4]

Same here

node: 14.0.0 npm: 6.14.4

this one worked for me

i'v Downgraded to 12.12.0 and now is working fine here

[YukaLangbuana]

This works for me. Downgraded my node version to 12.12.0:

$ n 12.12.0 $ npx create-react-app react-sample

Works fine after that. Note that this is a temporary fix. A dependency broke (https://github.com/then/is-promise/pull/15) and they're working on it

@SylCard This happens with 12 as well.

require() of /Users/gopal/.npm/_npx/21435/lib/node_modules/create-react-app/node_modules/is-promise/index.js from /Users/gopal/.npm/_npx/21435/lib/node_modules/create-react-app/node_modules/run-async/index.js is an ES module file as it is a .js file whose nearest parent package.json contains "type": "module" which defines all .js files in that package scope as ES modules.
Instead rename /Users/gopal/.npm/_npx/21435/lib/node_modules/create-react-app/node_modules/is-promise/index.js to end in .cjs, change the requiring code to use import(), or remove "type": "module" from /Users/gopal/.npm/_npx/21435/lib/node_modules/create-react-app/node_modules/is-promise/package.json.

I was using node v12.16.2

Confirmed that this is working with 12.12.0

[sabin2000pro]

Am I the only one getting this error, or is it a problem with the node package manager? I can't seem to run my application on localhost 3000 using docker-compose and its tests, should we just wait or what should I do in this scenario?

@sabinlungudotcpp What node version are you using? I have seen the error to be different over different node versions.

[sabin2000pro]

@sabinlungudotcpp What node version are you using? I have seen the error to be different over different node versions.

I'm using v10.16.0, shall I upgrade it to 12 or do we just have to wait until the developers fix the dependencies?

[qubbit]

@sabinlungudotcpp Use exactly 12.12.0, I think that will work based on what I have seen other commenters saying. It worked for me too.

How do I upgrade to 12.12.0 from 10.16.0 using the terminal?

[sabin2000pro]

@sabinlungudotcpp Use exactly 12.12.0, I think that will work based on what I have seen other commenters saying. It worked for me too.

Can you please tell me which command to use? $ n says that the command isn't found.

[qubbit]

@sabinlungudotcpp If you are using NVM you can do

nvm install 12.12.0
nvm use 12.12.0

[sabin2000pro]

nvm install 12.12.0

The command doesn't work for me..

[qubbit]

@sabinlungudotcpp You need to install nvm to use that command
