How can I change my port into 4900 by using npm, because I can't change my port by using ng s --port 4900.

Message showing:

PS G:\PROJECTS\PetroHSE> ng s --port 4900
ng : The term 'ng' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again.

Probably you do not have angualar cli installed globally. Many people do, but you certainly do not have to (I definitely prefer not to)

You can use 2 ways to accomplish what you want:

  1. use npx: npx ng serve --port=4900 or npx ng s --port=4900 (s NOT -s)
  2. edit the file package.json In here you will find a part with scripts. You'll see that by default start script has ng serve in it. Edit this to ng serve --port=4900, save and exit. Then just run npm start. This option is more useful if you always want to start the server locally on this port.

it appears that Angular CLI is not installed globally.

Try running npm install -g @angular/cli

this command will install Angular CLI globally.
