This is probably very trivial, but I am hitting my head against the wall while I am trying to (unsuccessfully) install angular-cli.

I am following the official angular-cli documentation here.

mkotsollariss-MacBook-Pro:~ mkotsollaris$ npm -v
5.6.0
mkotsollariss-MacBook-Pro:~ mkotsollaris$ node -v
v8.9.4

Then I run npm install -g angular-cli which gives me:

mkotsollariss-MacBook-Pro:~ mkotsollaris$ npm install -g angular-cli

-bash: ng: command not found

I think I have tried almost everything on the web, and still can't make this to work.

My OS is MacOS High Sierra 10.13.2.

Any idea what am I missing here?

After several tries, I finally installed angular-cli successfully via nvm. In detail:

Install nvm:

curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.33.0/install.sh | bash
export NVM_DIR="/Users/mkotsollaris/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"
nvm --version
0.33.0

Then install node through nvm:

nvm install stable
nvm install node

Thereafter, install angular-cli:

npm install -g @angular/cli
mkotsolarissMBP:myapp mkotsollaris$ ng -v

  • Please try running this command again as root/Administrator. Did you try using sudo?
  • @VSG24 Not necessary, nor constructive. Flagged.
  • @SterlingArcher Running with sudo gives me "Warning "root" does not have permission to access the dev dir" which leads me to this which does not solve the issue...
  • Angular CLI GitHub page is the best resource for how to install the CLI. The link you are using is instructing you to install a version of the CLI that is no longer supported; hasn't been for many months.
  • This worked. Before using this method, the installed failed at the python library section.
  • Menelaos Kotsollaris - great answer. Thank you
  • Just curious... why did only installing through nvm work? :(
  • A very minor correction: use 'ng version' in Angular CLI: 7.2.3. Just 'ng -v' now yields the list of available commands (including version :)
  • Can anyone explain why using nvm worked while using sudo npm install -g @angular/cli and linking did not work?
  • Works great. Thanks!
  • Thanks, this was useful
  • simplest solution!
  • thanks but that didn't work for me; I ended up installing @angular/cli through nvm.
