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
