Answer 1

I was facing this issue today. There were nothing wrong in my case, but just a silly mistake. I was running my command ng serve and other angular cli commands outside of my app directory(which contains the node_modules . So, after move to that directory using cd m4moviesapp , and then run ng serve everything was working as expected.

Directory

Before

After

我弄清楚了，我在git环境中工作，有人推了一个npmrc文件，其设置只允许从我们的内部服务器下载，这就是为什么每次我运行npm install都会出现错误，试图下载angular-cli。

Answer 3

This is because you have install angular in some directory and trying to use ng serve without creating your new project set-up
Generating and serving an Angular project via a development server ng new PROJECT-NAME cd PROJECT-NAME ng serve https://www.npmjs.com/package/@angular/cli#generating-and-serving-an-angular-project-via-a-development-server

Answer 4

我运行了“ npm install”，我的项目获得了所有模块，并且运行了。
