angular - 任何端口已在使用中.使用“--port"指定不同的端口 [英] angular - ANY port is already in use. Use '--port' to specify a different port

问题描述

当我使用 ng s 或 ng serve 运行时，任何端口都在使用中

When I will running with ng s or ng serve, any port is in use

我没有项目运行，我可以放任何端口，问题发生了.

I haven't project runing, I can put any port, the problem happen.

如果我在 angular 中尝试另一个项目，则可行

if I try another project in angular, works
