Bundle says gem is missing - but it's not?

Question

Background

I am maintaining the content of a Ruby On Rails site, but I really have no experience with Rails.

When trying to run the Rails server: rails s I get this:

Could not find activesupport-3.2.0 in any of the sources

Run bundle install to install missing gems

I run bundle install

Gem::InstallError: factory_girl requires Ruby version >= 1.9.2. An error occured while installing factory_girl (3.2.0), and Bundler cannot continue.

Make sure that gem install factory_girl -v '3.2.0' succeeds before bundling.

Okay, I install factory_girl as per the instructions:

Successfully installed factory_girl-3.2.0 1 gem installed

Run bundle install again:

Gem::InstallError: factory_girl requires Ruby version >= 1.9.2. An error occured while installing factory_girl (3.2.0), and Bundler cannot continue. Make sure that gem install factory_girl -v '3.2.0' succeeds before bundling.

Do you have any idea?

Info

Yesterday I got a cross-tread error when trying to run rails server. So as per this SO advice I advice I've nuked RVM and installed rbenv and bundler instead of RVM.

I have tried with both Ruby 1.9.3-p125 and 1.9.3-rc1

Output of gem list shows factory_girl as installed.

• ...
• factory_girl (3.2.0)
• ...

Output of gem environmentshows the problem might has something todo with ruby 1.9.1 being installed also?

Solution 1

@jdoe answered in the comments. And it worked. Apparently I needed to delete Gemfile.lock.

I don't know why or how though. I am just posting this here, until @jdoe shows up and collects his points with a real answer.

Solution 2

Try reinstalling all the gems with the following command:

bundle install --redownload

Solution 3

Have you tried this?

bundle exec rails s

Deleting the lock file means implicitly updating all the gems to the latest versions, which you might not want to.
