Duplicate module name: react-native-vector-icons

问题

When I install NativeBase and React-Native-Router-Flux in my react-native project I get this error:

Failed to build DependencyGraph: @providesModule naming collision:
  Duplicate module name: react-native-vector-icons
  Paths: /Users/vittori/Desktop/repos/GitHubExamples/native-starter-kit/node_modules/react-native/local-cli/core/__fixtures__/files/package.json collides with /Users/vittori/Desktop/repos/GitHubExamples/native-starter-kit/node_modules/react-native-router-flux/node_modules/react-native/local-cli/core/__fixtures__/files/package.json

This error is caused by a @providesModule declaration with the same name across two different files.

yarn add react-native-router-flux@3.38.0

回答2:

You should be able to update react-native-router-flux using: npm i react-native-router-flux --save

It may be that trying to start the react-native packager fails again and running may be useful:

1. Clear watchman watches: `watchman watch-del-all`. 2. Delete the `node_modules` folder: `rm -rf node_modules && npm install`. 3. Reset packager cache: `rm -fr $TMPDIR/react-*` or `npm start --reset-cache`.

You may see once attempting to run the packager again errors such as:

Failed to build DependencyGraph: @providesModule naming collision: Duplicate module name

You may need to run the npm install for react-native-router-flux again.

回答3:

If you work with yarn, please run this command. yarn add react-native-router-flux@3.38.0

And if you work with npm, please run this command. npm install react-native-router-flux@3.38.0 --save

Also you still get the issue, please downgrade react-native version to 0.41.2.

Then, it will work.
