Problems rake db:create

Hi,

i have some problems by type in rake db:create

It always says:

rake aborted! can't activate rails (= 2.3.5, runtime) for , already activated rails-3.0.0 for

I have set Rails version to 2.3.5 but the problem still exists. I want to install the OpenSource Project webpraca. Maybe somebody has the same problem.

Thanks for help

Since you have both RAILS 3.0.0 and 2.3.5, RAILS 3.0.0 is gettting loaded first.

You can either uninstall the RAILS 3.0.0 GEM, or migrate your RAILS 2.3.5 App to use bundler. (http://gembundler.com/rails23.html).

Ah okay. That works. I have uninstalled 3.0.0. (For them with the same problem: gem uninstall rails --version 3.0.0)

Thank you Srikanth

How have you done this? The correct way involves setting RAILS_GEM_VERSION in config/environment.rb. Is that what you did?

There was no need for you to remove Rails 3. Your project should still be able to run the older version.

Hey thanks for your answer

I have done it like you said and changed it in the environment. But now i will get a bigger issue:

When i change it to version 2.3.5 i will get this message. If i turn it back to 3.0.0 i will get this message:

"./script/server /Library/Ruby/Site/1.8/rubygems.rb:233:in `activate': can't activate rails (= 2.3.5, runtime) for , already activated rails-3.0.0 for (Gem::LoadError)   from /Library/Ruby/Site/1.8/rubygems/custom_require.rb:35:in `require'   from /Users/Mark/Rails/studiflex/config/boot.rb:55:in `load_initializer'   from /Users/Mark/Rails/studiflex/config/boot.rb:38:in `run'   from /Users/Mark/Rails/studiflex/config/boot.rb:11:in `boot!'   from /Users/Mark/Rails/studiflex/config/boot.rb:110   from ./script/server:2:in `require'   from ./script/server:2"

Could anybody help? Don´t know.
