And one more question, I need to install rails should I use the "sudo" command or not? Could you help me? thank you in advance!

I try to fix this looking online but I couldn't. I try change the permissions, I try to reinstall brew and nothing work.

Solution

Take a look at the ownership of your directory there, probably you did something with sudo that you shouldn't have and that directory is owned by root and not your own user. Probably you need to do a sudo chown -R $USER /Users/pedrodiogo/.local
