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/cli@8.3.6 postinstall /usr/local/Cellar/node/11.10.0/lib/node_modules/@angular/cli
> node ./bin/postinstall/script.js
+ @angular/cli@8.3.6
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
