npm install not working. Says that I need to check permissions?

Question

I'm trying to install eslint on my machine right now but it is saying that I need to check permissions because its missing write access to /user/local/lib/node_modules. Does anyone know how to fix this? Thanks!

npm install -g eslint

Answer 1

Try sudo npm install -g eslint

Answer 2

In my case I had this same problem to install angular, so just change the command to :

$ sudo npm install -g @angular/cli
