Installation on Ubuntu
- https://www.ruby-lang.org/en/documentation/installation/
- apt-get install ruby will install v1.8 or v1.9.
- 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 rvm install ruby-2.1.4
The last step will take a while since no binary rubies were available and it has to compile Ruby from source.
Then check ruby versions installed and in use
rvm list rvm use --default ruby-2.1.4
