Install Ruby 3.0.0 with asdf


It is assumed that asdf has already been installed.


asdf plugin-add ruby


Even if I try to execute the asdf list-all ruby command It seems that only 3.0.0-rc1 is listed yet. (As of December 26, 2020)




Specify the build version with the following command and install.


ASDF_RUBY_BUILD_VERSION=v20201225 asdf install ruby 3.0.0



#Confirm installation
asdf list ruby

#Globally designated&shim regeneration
asdf global ruby 3.0.0
asdf reshim ruby

#Shell restart or reload

#Version confirmation
ruby -v
ruby 2.6.3p62 (2019-04-16 revision 67580) [universal.x86_64-darwin20]

#Confirmation of substance

asdf which ruby
