The instructions didn't work for me as-is

[scbrady]

In order to get my React-Native project running, I had to do two extra things that aren't written in the readme:

1. Add the metro-bundler package to the native project: yarn add --dev metro-bundler
2. Add an empty object for the config param in rn-cli.config.js

   const getConfig = require('metro-bundler-config-yarn-workspaces')
   module.exports = getConfig(__dirname, {})

   Otherwise, I would get Cannot read property 'nodeModules' of undefined.

I can sent a PR if these are legitimate issues and if they weren't specific to my use case.

Is your project made using create react native app or react native's cli?

[scbrady]

@dariocravero It was using create react native app

Also along these lines, jest cannot be run from within the native app.

@scbrady I just realised that your issue was that getConfig doesn't have a default for the options object, sorry about that. Could you try v1.0.2? I just released a fix with default options on it. Also, do you still need metro-bundler? I tried the process again and didn't need to install it.

Thanks!

@bcarroll22 what errors are you seeing?

[scbrady]

@dariocravero Thanks, I no longer have to provide the empty object now. But I do still need metro-bundler, if I take it out, I get this error: Error: Cannot find module 'metro-bundler/src/blacklist'

And as far as jest goes, there are a lot of errors that come up, I tried getting it to work for hours last night.

At first, you get this: Error: Cannot find module '/Users/asdf/Documents/Code/referral/native/node_modules/jest/bin/jest.js' But you can fix it by changing the test script: "test": "node ../node_modules/jest/bin/jest.js"

Then you get this: Module <rootDir>/node_modules/jest-expo/src/setup.js in the setupFiles option was not found. And there are multiple ways to get around this, but even when you do, you end up at this error: Cannot find module 'setupDevtools' from 'setup.js' I couldn't get past that error reliably.

This is the best description of the problem that I found: https://github.com/facebook/react-native/issues/17469

Just seen this thread - I made an issue the other day regarding the 'metro-bundler' issue: #10

It seems like create react app installs metro-bundler into the 'metro' folder. Installing metro-bundler manually is the workaround I'm using for now
