执行npm install --save react-navigation后，项目无法运行。 - 十七度

报错信息如下

error: bundling: UnableToResolveError: Unable to resolve module `react` from `/Users/luzhuang/develop/shiqidu/index.ios.js`: Module does not exist in the module map or in these directories:
  /Users/luzhuang/develop/shiqidu/node_modules

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 packager cache: `rm -fr $TMPDIR/react-*` or `npm start -- --reset-cache`.

原因

可能是npm5有bug

解决方法

使用yarn代替npm install

yard add代替npm install --save

yarn add react-navigation
