Installing cucumber and jruby

Yet another note for myself…

At work I run Linux Mint 12 on my workstation and needed to install cucumber on top of jruby. The reason for choosing jruby is another story.

At first I tried to do with the pre-build packages for Mint, but did not have any luck. Then Frank told me to use rvm (Ruby Version Manager), and that was a good advice. It took me less than 10 minutes to get up and running. This was what I did:

To install rvm (Ruby Version Manager):

# curl -L | bash -s stable --ruby

The installation adds this line to .bash_login:

# [[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm"

On my system, bash only reads .bashrc on login – not .bash_login – so I had to choose one of the following solutions. Since my .bash_login originally was empty, thus only had the stuff that rvm added, and I since I’m a lazy bastard I did this.

# echo ~/.bash_login >> ~/.bashrc

Which is basically the same as:

# echo '[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm"' >> ~/.bashrc

But I guess you just as well can include .bash_profile in .bash_rc like this

# echo 'source ~/.bash_login' >> ~/.bashrc

Now you can install jruby using rvm:

# rvm install jruby

Set jruby to be the active ruby

# rvm use jruby

Now Install cucumber using jruby’s gem

# gem install cucumber

And I was ready to go…
