发生未处理的异常：找不到模块 'C:\\Users\\...\\node_modules\\@angular-devkit\\build-angular\\src\\dev-server'

Question

I am trying to run my angular project on another system I copy pasted all the required files(hopefully) and when I try to run the project using ng serve it throws this error

An unhandled exception occurred: Cannot find module 'C:\Users\...\node_modules\@angular-devkit\build-angular\src\dev-server'
Require stack:

See "C:\Users\acer\AppData\Local\Temp\ng-GYuFL2\angular-errors.log" for further details.

I searched on the web for this type of error but I didn't found any relevant post or I couldn't understand other posts

Any Help will be appreciated

尝试删除 node-modules 文件夹并运行npm install .. 也可能正在检查两个环境中的 angular 全局版本
