Question

我有React-native项目。当我想启动它时，我运行npm start或yarn start，得到的是：

jest-haste-map: Watchman crawl failed. Retrying once with node crawler.
  Usually this happens when watchman isn't running. Create an empty `.watchmanconfig` file in your project's root folder or initialize a git or hg repository in your project.
  Error: Watchman error: too many pending cache jobs. Make sure watchman is running for this project. See https://facebook.github.io/watchman/docs/troubleshooting.html.

如果我卸载wathcman Packeger，就会卡住。创建.watchmanconfig文件也无济于事。
