Error after updating to Rails 3.0.5

I just upgraded to Rails 3.0.5 and installed the updated gems.

When I run the command "rails -v" to chec开发者_高级运维k what version I'm on.. I get the following error:

Could not find activesupport-3.0.4

Any idea of what could be causing this? When I run gem list I get the following versions for ActiveSupport:

activesupport (3.0.5, 2.3.5, 2.2.2, 1.4.4)"

---

It may be the Gemfile.lock specifies 3.0.4. Perhaps remove that file (rm Gemfile.lock)?

open your Gemfile, change your version of Rails to 3.0.5 and then run

bundle install
