Angular - ng: command not found

Question

I am trying to learn Angular and my knowledge in terminal is beginner. After I installed Angular and then type ng new my-project. I get the response ng: command not found. I've seen other posts that had this problem and I've uninstalled and reinstalled npm and ng.

The last step I took was npm install -g @angular/cli@latest then ng new my-project.

Then I get ng: command not found.

Answer 1

Before wasting lots of time in installing and uninstalling, read this.

If you already installed angular before and found this issue, may be it is the reason that you installed angular before with running terminal as Administrator and now trying this command without administrator mode or vice versa. There is a difference in these two.

If you installed angular without administrator mode you can only use angular commands such as ng without administrator mode. Similarly,

If you installed angular with administrator mode you can use angular commands such as ng in administrator mode only.

You can install npx to use Angular CLI installed in your directory:

npm install -g npx
npx ng serve

Answer 4

just install npm install -g @angular/cli@latest

Answer 5

If you are working on Windows then do the following:

From this directory:

C:\Users\ [your username] \AppData\Roaming , delete NPM folder then install Angular using this command npm install -g @angular/cli

Answer 6

if you install npm correctly in this way:

npm install -g @angular/cli@latest

and still have that problem, it maybe because you run the command in shell and not in cmd (you need to run command in cmd), check this out and maybe it helps...
