macOS pre-installed ruby it’s quite unusable to use modern ruby tools, during time I struggled to have a proper setup for it. Since I found myself installing Fastlane on new machines and everytime I have to remember wich way it worked better I’m writing this as a refernce primarly for me, but I am sure it could be helpful for others too.
Brew
If you develop on a mac and you haven’t already installed brew you are mad.
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
rbenv
We’ll need a ruby version manager to remain sane I found rbenv to be the less evil:
brew install rbenv ruby-build
Add this to your .bashrc or whatever your poison is to load bash or zsh or ???:
if which rbenv > /dev/null; then eval "$(rbenv init -)"; fi
ruby
Install a newer ruby with rbenv:
rbenv install 2.4.1rbenv global 2.4.1
Fastlane
Finally we can install Fastlane whith the new shiny ruby environment we have:
gem install fastlane
this way you can install also cocoapods, for example, and remain sane.
