Angular 'ng' 未被识别为内部或外部命令、可运行程序或批处理文件，无法在本地主机外访问 angular 应用程序

Question

I am getting "'ng' is not recognized as an internal or external command, operable program or batch file." when I am trying to run ng serve --host 0.0.0.0 form my command prompt.

But as I run it via node.js command prompt , my issue resolve and I was able to run ng serve --host 0.0.0.0

Another thing,

It also ran when I prefix it with npm run to ng serve (as mentioned in a github issue), I was able to bring the services up. But then I was facing issue if I add --host 0.0.0.0 to npm run ng serve as it was throwing the following error.

D:\NewAngular\NewAngular\Angular\Feedback>npm run ng serve --host 0.0.0.0

> feedback@0.0.0 ng D:\NewAngular\NewAngular\Angular\Feedback
> ng "serve" "0.0.0.0"

Since, I have to access the webapp outside localhost, that's why I am adding --host 0.0.0.0

Is there any better way to do, so that I can access from any system within my company.network. Please help me with a proper solution.

Can anyone tell me the reason why? What is happening which I am unable to get.?

Answer 1

Try running as

D:\\NewAngular\\NewAngular\\Angular\\Feedback>npm run ng serve -- --host 0.0.0.0

This will pass host argument to the command mentioned in ng serve and not npm run as such

Answer 2

I recommend running your terminal with root/administrative privileges.
