Ruby plugin for rtx version manager
rtx plugin add ruby
Please make sure you have the required system dependencies installed before trying to install Ruby. It is also recommended that you remove other ruby version managers before using rtx-ruby
Check rtx readme for instructions on how to install & manage versions of Ruby.
When installing Ruby using rtx install, you can pass custom configure options with the env vars supported by ruby-build.
Under the hood, rtx-ruby uses ruby-build to build and install Ruby, check its README for more information about build options and the troubleshooting wiki section for any issues encountered during installation of ruby versions.
You may also apply custom patches before building with RUBY_APPLY_PATCHES, e.g.
RUBY_APPLY_PATCHES=$'dir/1.patch\n2.patch\nhttp://example.com/3.patch' rtx install ruby 2.4.1
RUBY_APPLY_PATCHES=$(curl -s https://raw.githubusercontent.com/rvm/rvm/master/patchsets/ruby/2.1.1/railsexpress) rtx install ruby 2.1.1
Running rtx plugin-update ruby will update rtx-ruby and ensure the latest versions of ruby are available to install. By default rtx-ruby uses the latest release of ruby-build, however instead you can choose your own branch/tag through the RTX_RUBY_BUILD_VERSION variable:
RTX_RUBY_BUILD_VERSION=master rtx install ruby 2.6.4
rtx-ruby can automatically install a set of default gems right after
installing a Ruby version. To enable this feature, provide a
$HOME/.default-gems file that lists one gem per line, for example:
bundler
pry
gem-ctags
You can specify a non-default location of this file by setting a RTX_GEM_DEFAULT_PACKAGES_FILE variable.
rtx uses the .tool-versions for auto-switching between software versions.
To ease migration, you can have it read an existing .ruby-version file to
find out what version of Ruby should be used.
If you are moving to rtx-ruby from another Ruby version manager, it is recommended to completely uninstall the old Ruby version manager before installing rtx-ruby.
If you install rtx and rtx-ruby and it doesn't make ruby and irb available in your shell double check that you have installed rtx correctly. Make sure you have system dependencies installed BEFORE running rtx install ruby <version>. After installing a Ruby with rtx, run type -a ruby to see what rubies are currently on your $PATH. The rtx ruby shim should be listed first, if it is not rtx is not installed correctly.
Correct output from type -a ruby (rtx shim is first in the list):
ruby is /Users/someone/.local/share/rtx/installs/<RUBY_VERSION>/ruby
ruby is /usr/bin/ruby
Incorrect output type -a ruby:
ruby is /usr/bin/ruby
