npm安装后ng服务构建错误

Question

ng serve删除node_modules目录并使用新建目录后,我在使用cmd的angular2应用程序中收到以下错误npm install.

Error: Cannot find module 'common-tags'
    at Function.Module._resolveFilename (module.js:337:15)
    at Function.Module._load (module.js:287:25)
    at Module.require (module.js:366:17)
    at require (module.js:385:17)
    at Object.<anonymous> (/usr/local/lib/node_modules/angular-cli/models/config.js:8:21)
    at Module._compile (module.js:425:26)
    at Object.Module._extensions..js (module.js:432:10)
    at Module.load (module.js:356:32)
    at Function.Module._load (module.js:311:12)
    at Module.require (module.js:366:17)

也npm install common-tags手动添加它不起作用

看起来你应该更新你的 Angular-cli 并清理缓存

npm uninstall -g @angular/cli
npm cache clean --force 
npm install -g @angular/cli@latest
npm install
