Answer 1

First install Homebrew if you don't have it: https://brew.sh/index_pt-br

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"

Second, install ruby if you don't have it: https://www.ruby-lang.org/pt/documentation/installation/

brew install ruby

You can also follow these steps: https://gist.github.com/monicao/d372716cdfbb7e9cf692

Then, close your terminal and reopen it again.

Always use sudo to install cocoapods:

sudo gem install cocoapods
