Question

我尝试了所有给定的解决方案，例如更新 angular / cli ，甚至卸载并重新安装 node / npm 。我可以创建一个新项目，它可以按预期工作，但是当我尝试在现有项目上运行ng serve命令时，它向我显示以下错误。请帮助解决此问题。

Answer 1

I resolved this problem, It was a missing module problem so i need to perform these 2 steps:

1.Remove node_modules folder from project directory.

Run command npm install (This will reinstall all missing modules)

After this ng serve command works fine.

Angular 2项目中的ng serve命令提示错误549
