reactjs – 撤消’npm run eject’的反应

我试图用反应CDN脚本来测试我的React应用程序(使用create-react-app创建)的性能,然后我做了’npm run eject’来添加 webpack externals依赖项反应和反应.
 
我在webpack配置和< script>中轻松完成了在index.html中

...
externals: {
    react: 'React',
    'react-dom':'ReactDOM'
},
...

现在我想将它恢复到以前的状态

我正在使用git,我在一个单独的分支中进行了这个实验.

我跑了git checkout master和npm start

结果很烦人

> myapp@0.18.1 start /home/code/serverSync/myapp/ui
> react-scripts start

sh: 1: react-scripts: not found

我怎样才能恢复到主分支？

如果您现在处于主分支(哪个配置与npm run eject之前相同),请尝试以下操作.

>删除node_module> npm安装> npm开始
