This is an error with npm itself (v6.9.0)

I tried installing dependencies for my project using npm i

What Happened Instead

I got an error which was :

npm i

Hi @ahmedisam99! There is an open issue with installing global packages using sudo leaving behind files with the wrong ownership.

The short version is run this to fix the ownership, then try your install again:


sudo chown -R $(whoami) ~/.npm

The long version and canonical bug is: Global installs (sudo npm i -g) fail on Mac after 6.5 upgrade. Works fine after 6.4.1 downgrade.
