I also tried adding it to the Enviorment Variables under PATH: (C:\\Users\\Administrator\\AppData\\Roaming\\npm\\node

Answer 1

make sure environment variables are set properly.

control panel-> system->advanced system settings-> select advanced Tab->
click on environment variables

and make sure in the path below line is available

`C:\Users\username\AppData\Roaming\npm`   

here username will get changed based on the user

.

still if its not working yourenvironment variables are not getting reflected so please restart your machine it will work fine

if still you are facing issue your angular cli is not installed properly

please run below commands for reinstalling

   npm uninstall -g @angular/cli

    npm cache clean    or   npm cache clean  --force

    npm install -g @angular/cli@latest
