Ruby plugin for asdf version manager

asdf-ruby

Build Status

Ruby plugin for asdf version manager

Install

asdf plugin add ruby https://github.com/asdf-vm/asdf-ruby.git

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 asdf-ruby

Use

Check asdf readme for instructions on how to install & manage versions of Ruby.

When installing Ruby using asdf install, you can pass custom configure options with the env vars supported by ruby-build.

Under the hood, asdf-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=$'dir/1.patch\n2.patch\nhttp://example.com/3.patch' asdf install ruby 2.4.1
RUBY_APPLY_PATCHES=$(curl -s https://raw.githubusercontent.com/rvm/rvm/master/patchsets/ruby/2.1.1/railsexpress) asdf install ruby 2.1.1

NOTE: This plugin does not automatically fetch new Ruby versions. Running asdf plugin-update ruby will update asdf-ruby and ensure the latest versions of Ruby are available to install.

By default asdf-ruby uses a recent release of ruby-build, however instead you can choose your own branch/tag through the ASDF_RUBY_BUILD_VERSION variable:

ASDF_RUBY_BUILD_VERSION=master asdf install ruby 2.6.4

Default gems

asdf-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 ASDF_GEM_DEFAULT_PACKAGES_FILE variable.

Migrating from another Ruby version manager

.ruby-version file

asdf 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. To do this, add the following to $HOME/.asdfrc:

legacy_version_file = yes

If you are migrating from version manager that supported fuzzy matching in .ruby-version like rvm or chruby, note that you might have to change .ruby-version to include full version (e.g. change 2.6 to 2.6.1).

Troubleshooting

NOTE: The most common issue reported for this plugin is a missing Ruby version. If you are not seeing a recent Ruby version in the list of available Ruby versions it's likely due to having an older version of this plugin. Run asdf plugin-update ruby to get the most recent list of Ruby versions.

If you are moving to asdf-ruby from another Ruby version manager, it is recommended to completely uninstall the old Ruby version manager before installing asdf-ruby.

If you install asdf and asdf-ruby and it doesn't make ruby and irb available in your shell double check that you have installed asdf correctly. Make sure you have system dependencies installed BEFORE running asdf install ruby <version>. After installing a Ruby with asdf, run type -a ruby to see what rubies are currently on your $PATH. The asdf ruby shim should be listed first, if it is not asdf is not installed correctly.

Correct output from type -a ruby (asdf shim is first in the list):

ruby is /Users/someone/.asdf/shims/ruby
ruby is /usr/bin/ruby

Incorrect output type -a ruby:

ruby is /usr/bin/ruby
