React Native 踩坑： UnableToResolve

使用React Native 开发，安装npm依赖必不可少，但是前几日开发中，却在这个环节栽了跟头，被卡住了几个小时。

问题

Metro Bundler ready.
Loading dependency graph, done.
error: bundling failed: Error: Unable to resolve module `AccessibilityInfo` from `D:\Workspace\Kart\app\node_modules\react-native\Libraries\react-native\react-native-implementation.js`: Module `AccessibilityInfo` does not exist in the Haste 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-*`.

目前的版本：

D:\Workspace\Kart\app> react-native -v
react-native-cli: 2.0.1
react-native: 0.56.0

最后查到官网，原来这个版本根本就是有问题的：
Thanks for reporting this. This is indeed a breaking change for plugins. In order to prevent having to override the hasteImplModulePath configuration in end-user code, we're going to add an exception for react-native-windows in react-native. I'm working in a fix right now.

Meanwhile, we're going to work in a long-term solution for overriding core components from plugins, as the current approach is pretty hacky.
