安装react 脚手架发现报错
然后一不小心这个点了
error F:\react\study\my-react-app\node_modules\core-js: Command failed.
Exit code: 1
Command: node -e "try{require('./postinstall')}catch(e){}"
Arguments:
Directory: F:\react\study\my-react-app\node_modules\core-js
Output:

Deleting my-react-app/ from F:\react\study
Done.
解决办法
把yarn卸载掉
npm uninstall yarn -g然后就
Success! Created my-react-app at F:\react\study\my-react-app
Inside that directory, you can run several commands:
npm start
Starts the development server.
npm run build
Bundles the app into static files for production.
npm test
Starts the test runner.
npm run eject
Removes this tool and copies build dependencies, configuration files
and scripts into the app directory. If you do this, you can鈥檛 go back!
We suggest that you begin by typing:
cd my-react-app
npm start
Happy hacking!
初步分析
你本地安装yarn,下载依赖就是通过yarn去下载，这个时候安装脚手架会在core-js这里出现异常，然后就无法继续安装执行rm -rf命令删除掉node_module依赖文件就是下面报的错误
如果卸载yarn以后安装项目使用npm下载依赖
这里抛出异常以后就会接着继续安装依赖
综上所述应该是core-js这个依赖的问题 可跳转https://www.npmjs.com/package/core-js参考
接下来有空继续分析， core-js在vue-cli脚手架安装依赖的时候也会出问题，默认使用2.xcore-js版本但是4.x的脚手架需要升级到3.x的core-js
