一开始的ERROR信息是
error “@angular/compiler-cli” package was not properly installed
尝试方案二时又出现了以下的ERROR信息
npm ERR! code EINTEGRITY
npm ERR! sha1-OmJbxBx6n5nVnWRVKFfdGvDt2dQ= integrity checksum failed when using sha1: wanted sha1-OmJbxBx6n5nVnWRVKFfdGvDt2dQ= but got sha1-PVZuUT5szAqjMvKCcIwuIcpR9KY=. (259028 bytes)
npm ERR! A complete log of this run can be found in:

尝试了多种方案
方案一(失败)
清除缓存
npm cache verify
方案二(失败)
1.Uninstall and clean (global)
rm -rf node_modules dist
npm uninstall -g @angular/cli
npm cache verify
2.Reinstall and play (global)
npm install -g @angular/cli@latest
npm install
ng serve
最终的解决办法是
grep -ir "sha1-OmJbxBx6n5nVnWRVKFfdGvDt2dQ= integrity checksum" (npm的安装目录)
再次运行 npm install
然后全局更新TypeScript和angular cli ,再目录更新TypeScript和angular cli
ng server 完成
