Answer 1

In case others come here with this issue as I have, here is how I solved it system-wide on MacOS. Hope this helps.

Verify node is installed:

$ node -v
v11.2.0

Verify npm is installed:

$ npm -v
6.4.1

Verify your npm global install file path is configured (known as prefix). Mine is under ~/.npm-packages:

$ npm config ls -l | grep prefix
prefix = "/Users/christiangroleau/.npm-packages"

If not, you can place it into your ~/.npmrc file:

echo prefix=~/.npm-packages >> ~/.npmrc

Verify that your prefix path is listed in your system PATH:

$ echo $PATH
/Users/christiangroleau/.npm-packages/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin

If not, invoke the following:

export PATH="$HOME/.npm-packages/bin:$PATH"

Finally, you can reinstall angular-cli (in my case I needed to install it globally):

$ npm install -g @angular/cli

Verify installation:

$ ng -v

Answer 2

Based on your comments to other answers: This npm issue might be related to your problem, your npm installation might be outdated.

First of check whether you use a recent version of node. Then update npm with npm i -g npm as the issue suggests (near bottom). Then if ng is still not found follow the update instructions of @angular/cli:

npm uninstall -g @angular/cli
npm cache verify
# if npm version is < 5 then use 'npm cache clean'
npm install -g @angular/cli@latest

Answer 3

If you have installed the dependencies locally and need to refer those packages instead of global. use npx before the the command eg: npx ng build refers to the locally installed package. ng build refers to the global package.

Answer 4

npm doesn't recognize ng command.

Try this command:

npm link @angular/cli

to link npm and angular-cli.

Answer 5

You need to install the Angular CLI globally. Run npm install -g @angular/cli
