react-native watchman 错误，在 Ubuntu 17.10 上启动 npm 之后。

  • 772

我正在尝试在 Ubuntu 上启动 React-native 项目，node、npm 是最新版本。根据文档，我已经安装了所有官方create-react-native-app及其依赖项。

这是 npm start 后的输出屏幕

gd@gd:~/Desktop$ cd testing7/
gd@gd:~/Desktop/testing7$ npm start

> [email protected] start /home/gd/Desktop/testing7
> react-native-scripts start

  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.
