学完9-3关机了，第二天npm start后报错：

Failed to build DependencyGraph: @providesModule naming collision:

  Duplicate module name: EventPluginUtils

  Paths: G:\desktop\demo\node_modules\react-native\Libraries\Renderer\src\renderers\shared\stack\event\EventPluginUtils.js collides with G:\desktop\demo\node_modules\react-native\Libraries\StyleSheet\ColorPropType.js

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

于是我删除node_module，重新npm install，这个错误依然存在，即使用git把代码回退到以前的版本，这个bug还是存在，没有百度到合适结果。PS：windows10系统
