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? -Kedar ---

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.

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… -Kedar ---

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, Schalk ---

To go one step farther, I would recommend installing RubyGems from source and then installing Rails through RubyGems. Much better situation. On Jan 18, 7:24 pm, “Jeremy McAnally” [removed\_email\_address@domain.invalid](mailto:removed_email_address@domain.invalid) ---

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. –Jeremy On Sun, Jan 18, 2009 at 7:13 PM, Kedar M.

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! -Kedar
