I got the “You don’t have write permissions for the /Library/Ruby/Gems/2.3.0 directory. ” error when I add gem install bundler in the Terminal. 

Below is the steps that I applied for my specs to install RSpec:

  • Run gem installer within the directory root of your application. 
  • Run bundle install. 
  • To run a single spec file, run a command like this: bundle exec rspec spec/00_hello_spec.rb. 
  • To run all specifications at once, execute bundle execute RSP

  1. You can install ruby that use homebrew

    brew install ruby
export GEM_HOME="$HOME/.gem"
gem install rails

    Include export GEM_HOME="$HOME/.gem" to the ~/.bash_profile or .zshrc if zsh is being used in your system.
