“You don't have write permissions for the /usr/bin directory.” when installing Sass using the Gem command

Question

I\'m on Mac and I\'m trying to install Sass using the command in terminal, \"sudo gem install sass\". I then enter my password, and everything works fine until this pops up

Answer 1

I used the same for bundler.

sudo gem install -n /usr/local/bin bundler.

It works.
