None of the above solutions alone worked for me  On Windows 7 this worked   Install Rapid Environment Editor and remove any entries for node  npm  angular-cli or  angular cli  Uninstall node js and reinstall  Run Rapid Environment Editor again and make sure node js and npm are in your System or User path  Uninstall any existing ng versions with   npm uninstall -g angular-cli  npm uninstall -g  angular cli  npm cache clean   Delete the C  Users YOU AppData Roaming npm node modules  angular folder   Reboot  then  finally  run   npm install -g  angular cli   Then hold your breath and run ng -v  If you re lucky  you ll get some love  Hold your breath henceforward every time you run the ng command  because  command not found  has magically reappeared for me several times after ng was running fine and I thought the problem was solved

I tried all the above things  and still ng as sticking around globally  So in powershell I ran Get-Command ng  and then it became clear what my problem was  I was using yarn heavily in the past  and all the old angular cli packages were also installed globally in the yarn cache location  I deleted my yarn cache for good measure  but probably could have just updated the global angular cli via yarn  In any case  I hope this helps remind some of you that if you use yarn  then global commands like ng can also live in another path than where npm puts them
