Updating ruby version does not work.

[iuri-gg]

I used role to install ruby from source on a given machine. Later, I changed ruby version/url to a newer release and re-ran the role against the machine. I was expecting new version of ruby to be installed on the system. However role skips installation of ruby from source if there is any ruby already present on the system.

Is this an expected and correct behaviour for the role? If not, I can try to fix it and submit a PR for it.

Thanks,
Iuri

You may remove the creates=/usr/local/bin/ruby line here :

ansible-role-ruby/tasks/install-from-source.yml

Lines 40 to 48 in 76e80c2

	- name: Build ruby.
	command: >
	{{ item }}
	chdir={{ workspace }}/ruby-{{ ruby_version }}
	creates=/usr/local/bin/ruby
	with_items:
	- ./configure --enable-shared
	- make
	- make install

But please note that this will ALWAYS compile & install ruby, so this is not perfect either.

We would need a way to know that the specific version of ruby was already compiled & installed, but the output file is always the same (/usr/local/bin/ruby). Would need to check the checksum of the files but I don't know how to do this simply with the Ansible language.

Changing it to support updating of installed ruby version when installing from source is easy. I was wondering if it is in the scope for this role or not installing from source when any version of ruby is present is desired behavior.

You don't have to check the checksum; you can parse the output of ruby -v to see if it matches what the user has set as the Ruby version. This would be really helpful for me, as I often need to update the version of Ruby on provisioned servers... Will see if I have time to assemble a PR for this.
