Updates for RN 0.56.0

[adamivancza]

I got two errors when I tried to run my project with RN 0.56.0-rc.2:

• error: bundling failed: Error: Cannot find module 'babel-preset-react-native-dotenv' from 'project'

• If you want to resolve "react-native-dotenv", use "module:react-native-dotenv"

• error: bundling failed: Error: Plugin/Preset files are not allowed to export objects, only functions. In project/node_modules/react-native-dotenv/index.js

Thanks @adamivancza! Would be great if we could get this rolled into master as I'm getting the same errors.

while we're waiting for the merge you can reference my fork directly: "react-native-dotenv": "https://github.com/adamivancza/react-native-dotenv"

@adamivancza I tried your branch, but I am still getting the same error.

[adamivancza]

@ashishmusale did you run npm install then restart your packager?

[ashishmusale]

Yes, I did. I deleted node_modules and ran npm install

Simple and excellent @adamivancza. Appreciate it!

Think we can get this one merged into master? Great fix @adamivancza !

Don't forget to update your .babelrc file @ashishmusale

[sibelius]

@zetachang can we get this in?

[zetachang]

Hey guys, thank you for working on this, I am looking into it and see if I could merge this and release a new version this weekend. 💪

If you're on react-native@0.56.0, things to consider:

1. Run cat yarn.lock | grep react-native-dotenv in your Terminal to see what's actually being resolved in your project. The result should look like:

react-native-dotenv@^0.2.0:
  resolved "https://registry.yarnpkg.com/react-native-dotenv/-/react-native-dotenv-0.2.0.tgz#311551cb6a35a3dcfede648bded55c0e3ece579d"

2. If you don't see this, I would be sure you have "react-native-dotenv": "^0.2.0", in your package.json, then, in Terminal, run:

watchman watch-del-all
killall -9 node
rm yarn.lock
yarn

3. Now, you should get the output above from your yarn.lock file in terms of what react-native-dotenv resolves to.
4. No need to rebuild, since this is just a JS package.
5. Check that your .babelrc file's "presets" line looks similar to:

   "presets": ["react-native", "module:react-native-dotenv"],

6. Restart your packager and run on your simulator/device!
