hi guys
I have a working rails application. I have rails 2.3.9 installed in my existing dev & prod machines.
When I run script/server, i keep getting an indication that rails 2.3.2 is being used. The message reads, "Loading development environment (Rails 2.3.2)".
I don't have rails 2.3.2 installed and yet this occurs. Furthermore, there is no reference to rails 2.3.2 in even my config/ environment.rb file.
Is there something wrong when I use "script/server"? what could be wrong?
thanks
Gordon
just to add, the machines that I have used that exhibit this behaviour are ubuntu 9 and 10.04.
Thank you
What does gem list show?
Colin
Hi,
Are you using bundler ? If so please do check bundle show rails on your root and check which version is being used.
@Colin - running "gem list --local", I observed rails is only 2.3.9 (ie. "rails (2.3.9)")
@Dhruva - no, I am not running bundler
Please don't top post, it is easier to follow the thread if you insert your post into the previous reply. Thanks
Can you show the complete output of gem list (run from the rails application root) please, also the complete output of script/server. Also rails -v ruby -v
Colin
Sorry, also post your environment.rb
Thanks

Does it just stop there, or is there more? Also is there anything in development.log? Does the app go on to function?

Here:
------- Start ----- *** LOCAL GEMS *** actionmailer (2.3.9) actionpack (2.3.9) activemodel (3.0.3) activerecord (3.0.3, 2.3.9)
So you have some rails gems from 2.3.9, some from 3.0.3 and some from both, and in environment.rb you ask for 2.3.5. I don't know why that would cause it to say it was loading 2.3.2 but it is certainly never going to work as it is. I think you need to sort out the versions. I would suggest installing rvm and starting again.

Probably because it's picking up 2.3.2 from vendor/rails.
but it is certainly never going to work as it is.

Agreed.

Best,

Good point, I had not thought of that. I should have done.
but it is certainly never going to work as it is.

I said it because I had not thought of a version frozen in vendor,
which I think is a perfectly good reason for saying it, even though as
a statement of truth it is fatally flawed

I did notice that it’s picking up 2.3.2 from vendor/rails.
I removed vendor/rails and when I ran “script/console”, it does not look for 2.3.2 anymore. Instead, it was 2.3.8 (as i specified “RAILS_GEM_VERSION = ‘2.3.8’ unless defined? RAILS_GEM_VERSION” in my config/environment.rb.
I then looked up all the gems in http://rubygems.org/gems/ and made sure the versions were the right ones as per my working development and production machines. Problem solved but i somehow think removing vendor/rails is not so right…

Where did you get that idea? Removing vendor/rails is exactly right in this case -- it's only purpose is to override the system Rails gems. If you want to freeze 2.3.8 into vendor/rails, you can do so.
Note, however, that 2.3.9, and I think 2.3.8, have serious security holes. I'd recommend upgrading to 2.3.10 as soon as possible.
Best,
Also don't forget that when you change the version you should run rake rails:update to update rails scripts etc.

Marnen, you were right on the money!
“Probably because it’s picking up 2.3.2 from vendor/rails.”.
thank you for that

Yep, I m testing the application and making sure it works on 2.3.8. Once it is stable, I shall look at 2.3.10
hello, Colin,
I shall do so. Thank you and Merry x’mas!

Hello,
yes, doesn't have anything with Ubuntu, but your gems are confused. Installing RVM really solves all your problems, and also prevents later: http://rvm.beginrescueend.com/
Ruby 1.8.7 + Gem 1,3,5 + Rails 2.3.8 and Ruby1.9 +Gem1.3.7+Rails3 works together fine.
When installing gems using RVM always pay attention not to use 'sudo' before commands, so the gems will be Ruby version dependent. So not "sudo gem install rails" instead only "gem install rails" after installing RVM and setting default Ruby.
Good luck, gezope
