asdf-ruby

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.

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

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

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

Rubies

asdf installs Rubies to $HOME/.asdf/installs/ruby, the directory structure is the same as other version managers, so you can just move the Rubies to this directory:

RVM

mkdir ~/.asdf/installs/
mv ~/.rvm/rubies ~/.asdf/installs/ruby/

rbenv

mkdir ~/.asdf/installs/
mv ~/.rbenv/versions/* ~/.asdf/installs/ruby/

chruby

mkdir ~/.asdf/installs/
mv ~/.rubies ~/.asdf/installs/ruby/
