Switch from RVM to rbenv:
Get Rid of RVM if it's installed:
Cleanup your .bash_profile/.bashrc/.zshrc file to remove RVM from the path:
You should have something like this left from RVM. Delete it from the file. ``[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm"```
Ensure your homebrew is working properly and up to date:
brew doctor brew update
Install Rbenv via homebrew:
brew install rbenv brew install ruby-build
Add ~/.rbenv/bin to your $PATH for access to the rbenv command-line utility:
Afterwards you'll still need to run
rbenv init. You'll only ever have to do this once.
(NOTE: Zsh note: Modify your ~/.zshrc file instead of ~/.bash_profile.)
Restart your shell so that PATH changes take effect!
(Opening a new terminal tab will usually do it.)
Now check if rbenv was set up by typing
rbenv into the terminal.
You should see something like this:
rbenv 0.4.0 Usage: rbenv <command> [<args>] Some useful rbenv commands are: commands List all available rbenv commands local Set or show the local application-specific Ruby version global Set or show the global Ruby version shell Set or show the shell-specific Ruby version install Install a Ruby version using ruby-build uninstall Uninstall a specific Ruby version rehash Rehash rbenv shims (run this after installing executables) version Show the current Ruby version and its origin versions List all Ruby versions available to rbenv which Display the full path to an executable whence List all Ruby versions that contain the given executable See `rbenv help <command>' for information on a specific command. For full documentation, see: https://github.com/sstephenson/rbenv#readme
To see a list of available Ruby versions for install:
rbenv install -l
PRO-TIP: Don't see the ruby version listed you are looking for (aka specified in your gemfile?)? Then you probably are due for a brew update!
brew upgrade ruby-build
Check the Ruby versions list again...
rbenv install -l
To install a ruby version:
rbenv install 2.3.0
Before you can bundle and install gems, add bundler:
gem install bundler
Then you can bundle & install all the gems in the gemfile!
cd your-project-folder bundle install
Set a project specific (local) ruby version:
cd your-project-folder rbenv local 2.3.0
