Intro
- Various development tools (such as CocoaPods, fastlane, twine, etc) are written in Ruby
- Since Ruby is an interpreter we can't just make a binary of needed tools, you have to install it locally
Ruby on macOS
- There is a default system Ruby in macOS which is limited for security reasons
- Therefore it is highly recommended to install a separate virtual environment for Ruby via environment manager
- Most popular managers are rbenv, rvm and chruby
- We have a good experience with rbenv
Setup rbenv on macOS
- Make sure you don't have any other manager/Ruby installed (
which ruby should outputs /usr/bin/ruby - system Ruby)
- If you have other manager/Ruby installed, look into the documentation of your manager and uninstall it completely 🙃
- Install rbenv via Homebrew:
brew install rbenv ruby-build (if you don't have Homebrew go to https://brew.sh/)
- Now we have to make sure that both Homebrew and rbenv are loaded into your shell
- This can be done by modifying your
~/.zshrc + ~/.zshenv files and restarting Terminal (for more info visit zsh)
- For Homebrew:
echo 'eval "$(/opt/homebrew/bin/brew shellenv)"' >> ~/.zshrc
- For rbenv:
echo 'eval "$(rbenv init - zsh)"' >> ~/.zshrc && echo 'export PATH="$HOME/.rbenv/shims:${PATH}"' >> ~/.zshenv
- Install and set a required Ruby version, for example:
rbenv install 3.2.2 && rbenv global 3.2.2
- Now you can install and use required gems, for example:
gem install twine 🤗
