I am using my admin account so i am not sure why it is not working, also i have installed node.js just fine without any issues.

Answer 1

Check if your application has package.json. If not then run

npm init 

If package.json exists try running

npm i

and then run

npm i -g @angular/cli

Answer 2

尝试使用--allow-root标志

sudo npm install @angular/cli -g --allow-root
