What version of rails am I running?

Rails
1

Sorry to ask a question that appears like the one posed by a n00b.
(Maybe I am going blind, seriously).

I have searched the forum for it, but couldn’t find it.

How can I tell which version of rails I am running? Doing “rails -v”
fails. That’s another question – why does it fail – why can’t it tell
me the version string?

That aside, rails -v tells you what the latest version of rails on
your computer is, which isn’t the same thing as what version your
rails apps are running.
That can be controlled by

  • having RAILS_GEM_VERSION set to something in environment.rb
  • having rails frozen into vendor/rails

when you run script/console or script/server it should tell you what
version of rails its loading.

Thank you. But I don’t think rails -v works. I think I have rails 2.0.2
or something like that (and that’s what I am trying to ascertain) but on
my Ubuntu here is what happens:
kedar@kedar-laptop:~/Projects/ror/people$ which rails
/usr/bin/rails
kedar@kedar-laptop:~/Projects/ror/people$ rails -v
getopt: invalid option – v
Terminating…

Hi there Kedar,

Try script/about or, alternatively you can do a gem list. If you have
only one version of rails installed gem list will indicate this.

HTH,

To go one step farther, I would recommend installing RubyGems from
source and then installing Rails through RubyGems. Much better
situation.

Yes, Ubuntu puts their own Rails binscript (written in bash. ugh!)
in there because apparently they hate you and the whole of the Rails
community for some reason.

Try something like “rails --version”. And file a bug with Ubuntu
because they’re the ones who maintain their stupid script.

Maybe then http://wiki.rubyonrails.org/rails/pages/Installation should
prefer RubyGems installation to “apt-get install ruby” (i.e. swap the
order).

I think Ubuntu screws this up further because apparently their rails
script does not identify -d mysql to mean database to use. Instead, it
treats it as a folder, apparently, for example, if I did:
$> rails -d mysql people => this rails is from apt-get
install rails

I get two folders created: “mysql” and “people”.

Instead, if I installed RubyGems and did gem update --system and then
used the rails from there, it works better. Unfortunately, this rails
script is located in /var/lib/gems/1.8/bin and the Ubuntu (faulty)
script is in /usr/bin. So, I need to use /var/lib/gems/1.8/bin/ before
/usr/bin in my PATH!

I think the community should be aware of this.

Thank you!
