Metro "Unable to resolve module redux ... Module does not exist in the module map" but we don't use redux

[willbattel]

• I have reviewed the documentation
• I have searched existing issues
• I am using the latest React Native version

Environment

Environment:
  OS: macOS High Sierra 10.13.4
  Node: 6.10.3
  Yarn: 1.6.0
  npm: 5.6.0
  Watchman: 4.9.0
  Xcode: Xcode 9.3 Build version 9E145
  Android Studio: 3.0 AI-171.4408382

Packages: (wanted => installed)
  react: 16.3.1 => 16.3.1
  react-native: 0.55.3 => 0.55.3

Steps to Reproduce

I'm not sure how this can be reproduced by others. This happened to me when I re-installed the remote project.

Expected Behavior

Project should run as it did before I deleted my local copy of the project.

Actual Behavior

1. Cloned previously-working project from remote Git
2. yarn install
3. cd ios && pod install
4. cd .. && react-native run-ios or, alternatively, Open Xcode, set to physical device, and run project.
5. In final steps of the build (Bundle React Native code and images), Xcode fails with this error:

Unable to resolve module `redux` from `path/to/node_modules/react-redux/lib/connect/mapDispatchToProps.js`: Module does not exist in the module map
This might be related to https://github.com/facebook/react-native/issues/4968
To resolve try the following:
  1. Clear watchman watches: `watchman watch-del-all`.
  2. Delete the `node_modules` folder: `rm -rf node_modules && npm install`.
  3. Reset Metro Bundler cache: `rm -rf /tmp/metro-bundler-cache-*` or `npm start -- --reset-cache`.
  4. Remove haste cache: `rm -rf /tmp/haste-map-react-native-packager-*`.

This must be a bug with React Native, please report it here: https://github.com/facebook/react-native/issues'

I've tried the suggested steps, and tried using both NPM and Yarn to install our dependencies.

It says it can't resolve redux but our project does not use redux save for our packages' peer-dependencies. It also says false != true, suggesting there is a logic error somewhere in my bundled code, but nothing has changed since it was last working. Finally, it says it can't find main.jsbundle, and I've confirmed that it is not being included in the packaged build for whatever reason.

The log suggests I report it, suggestions in #4968 haven't helped, and I don't know how to fix it, so here I am!

Installing redux resolved the issue for me 🤷‍♂️

[willbattel]

@t3chnoboy yeah that fixes it for us too, but we shouldn't have to install it if it's only a peer dependency.

@wbattel4607 Same doubt. But it seems appeared after I used react-native-root-toast. Did you have a use?

[Pines-Cheng]

appeared after I used react-native-root-toast...

This isn't an issue with React Native, so I'm closing this issue.
