macos - Angular CLI ng command not found on Mac Os

I looked at the numerous posts on here regarding this issue and tried them but had no success resolving this.

I am on MacOS and here is what I have done so far based on recommendations I have found here but I still get this error

 ~~ sudo npm uninstall -g angular-cli

 ~~ sudo npm uninstall -g @angular/cli

 ~~ sudo npm cache clean --force

 ~~ sudo npm install -g @angular/cli

This outputs:

/usr/local/Cellar/node/11.10.0/bin/ng -> /usr/local/Cellar/node/11.10.0/lib/node_modules/@angular/cli/bin/ng

> @angular/[email protected] postinstall /usr/local/Cellar/node/11.10.0/lib/node_modules/@angular/cli
> node ./bin/postinstall/script.js

+ @angular/[email protected]
added 245 packages from 185 contributors in 8.784s

However, issuing command below does not work:

 ~~ ng version

-bash: ng: command not found

Some people suggesting linking so I tried that as well:

 ~~ sudo npm link @angular/cli

, which outputs following:

/Users/dinob/node_modules/@angular/cli -> /usr/local/Cellar/node/11.10.0/lib/node_modules/@angular/cli

, but ng version is still not working:

 ~~ ng version

-bash: ng: command not found

Many posts suggest that there should be a directory .npm-global created under my /Users/dinob directory but I dont see it. I aonly see .npm directory, not .npm-global.

I also tried following:

uninstall angular as described above

brew update

brew upgrade node // this upgraded from 11.10.0 to 12.10.0

then repeat steps above to install angular/cli

still same problem, ng command not found

This is not a duplicate question as KenWhite suggests and I have reviewed all the posts on SO I could find (and more) regarding this issue, tried them and none of them solved the issue for me.

sudo npm install -g @angular/cli command completed and returned following paths but none of them @angular directory in them:

/usr/local/Cellar/node/11.10.0/bin/ng -> /usr/local/Cellar/node/11.10.0/lib/node_modules/@angular/cli/bin/ng 

Above, there is no bin folder:

dinob @ /usr/local/Cellar/node/11.10.0 
 ~~ ls -la

total 80

After days of googling and getting no help neither on here nor from @Angular github which is pretty much useless, was finally able to resolve the issue and get my angular ng command not found issue resolved following these steps:

1. Instal nvm

Issue these 3 commands to install nvm. (Angular documented steps https://angular.io/guide/setup-local to setup your environment did not work for me).

So I installed nvm like so:

curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.33.0/install.sh | bash

export NVM_DIR="/Users/your-user-name/.nvm"

[ -s "$NVM_DIR/nvm.sh" ] && . "$NVM_DIR/nvm.sh"

After this, make sure you restart terminal and you should be able to issue nvm --version to see version of installed nvm.

2. Install node using nvm

nvm install stable

nvm install node

3. Finally, install angular

npm install -g @angular/cli

4. Restart terminal

Restart terminal and you should be able to use ng version to see version installed on your system

 ~~ ng version


     _                      _                 ____ _     ___
    /    _ __   __ _ _   _| | __ _ _ __     / ___| |   |_ _|
   / △  | '_  / _` | | | | |/ _` | '__|   | |   | |    | |
  / ___ | | | | (_| | |_| | | (_| | |      | |___| |___ | |
 /_/   \_\_| |_|\__, |\__,_|_|\__,_|_|       \____|_____|___|
                |___/


Angular CLI: 8.3.6
Node: 12.11.1
OS: darwin x64
Angular: 
... 

Package                      Version
------------------------------------------------------
@angular-devkit/architect    0.803.6
@angular-devkit/core         8.3.6
@angular-devkit/schematics   8.3.6
@schematics/angular          8.3.6
@schematics/update           0.803.6
rxjs                         6.4.0

I can now create and start my project

ng new my-test-project

ng serve my-test project

enter image description here

I think SO should start getting serious about people down-voting questions or marking them as duplicates before reading them and even trying to understand what was asked and what the problem is.

It seems to be lots of people read the title and decide the fate of question just based on that and any disagreement ends up in blocking question entirely.

So much bias and hate on a site that is supposed to help.

Better alternatives are very much needed.

UPDATE

If you are like me and switched to use zsh shel instead of bash shell (since Catalina MacOs now uses zsh), you might have noticed that ng version has stopped working for you.

In that case, modify your .zshrc file by opening it in vim:

vi ~/.zshrc

In there, find this line:

source $ZSH/oh-my-zsh.sh

Underneath this line, add following line:

source /Users/Your-User-Name/.bash_profile

Save the file by hitting Esc key and typing :wq and hitting Enter

Restart your terminal

Reissue ng version and you should see it in your zsh shell:
