Angular 'ng' is not recognized as an internal or external command, operable program or batch file and accessing angular app outside localhost

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.?

find your IP using **ipconfig** and use it instead of 0.0.0.0 — vich, Oct 09 '18 at 09:40
I have tried Using IP and direct ng serve -- host but it didn't worked. Please read the question properly. — Debjyoti Pandit, Oct 09 '18 at 10:06

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

I think you didn't read my question properly. I clearly mentioned it is not working. – Debjyoti Pandit Oct 09 '18 at 10:04
@DebjyotiPandit my suggestion is add -- twice D:\NewAngular\NewAngular\Angular\Feedback>npm run ng serve -- --host 0.0.0.0 – Hari Prathap Oct 09 '18 at 10:25
It worked when I removed the space between -- and host. – Debjyoti Pandit Oct 09 '18 at 10:30
When you add -- it will pass the subsequent arguments to the script mentioned inside your npm script(ng serve in this case) Please refer: https://stackoverflow.com/questions/11580961/sending-command-line-arguments-to-npm-script – Hari Prathap Oct 09 '18 at 10:37
If you are familiar, help me in this. – Debjyoti Pandit Oct 09 '18 at 10:48

I recommend running your terminal with root/administrative privileges.
