Installation on Ubuntu
- https://www.ruby-lang.org/en/documentation/installation/
- apt-get install ruby will install v1.8 or v1.9. v1.8 is kind of old that nokogiri, for example, cannot be installed.
- I tried to install from the source (v2.2.1) on Ubuntu 14.04. The canonical method ./configure, make & sudo make install does not work at 'make' step. # See https://github.com/sstephenson/ruby-build/issues/690. Unfortunately the method of installing libffi-dev does not solve the error on Ubuntu 14.0.
- The next method is ruby-build. Don't quite follow it.
http://stackoverflow.com/questions/26595620/how-to-install-ruby-2-1-4-on-ubuntu-14-04 mentioned a couple of methods.
- rbenv method. Not sure if it works since the shell hangs when I run 'rbenv install 2.2.0'.
- rvm (ruby version manager) method.
sudo apt-get update sudo apt-get install build-essential make curl \curl -L https://get.rvm.io | bash -s stable source ~/.bash_profile # sudo apt-get install ruby-rvm time rvm install ruby-2.1.4
The last step will take a while (27 minutes in my case) since no binary rubies for my OS/architecture were available and it has to compile Ruby from the source. At the end of installing, it will show
Install of ruby-2.1.4 - #complete Ruby was built without documentation, to build it run: rvm docs generate-ri
Then check ruby versions installed and in use
which rvm # /home/brb/.rvm/bin/rvm ruby -v # ruby 2.1.4p265 (2014-10-27 revision 48166) [x86_64-linux] which gem # /home/brb/.rvm/rubies/ruby-2.1.4/bin/gem rvm list rvm use --default ruby-2.1.4
Documentation

- Ruby in 20 minutes from ruby-lang.org.
