奇怪的Ruby on Rails错误

Question

I ran bundle install and then rails s the other day and got the following error:

/Users/helixed/.rvm/gems/ruby-1.9.2-p180@rails31/gems/activerecord-1.6.0/lib/active_record/support/clean_logger.rb:5:in `remove_const': constant Logger::Format not defined (NameError)

I've read I can fix this by going into the clean_logger.rb file and commenting out that line, but I've never touched that file and I don't want to edit it if I can help it. Does anybody know what this file does or how I can fix this? I'm using Ruby 1.9.2 and Rails 3.1.0.rc4.

Update

Here's my Gemfile:

source 'http://rubygems.org'

gem 'rails'

gem 'sqlite3'

# Asset template engines

gem 'coffee-script'

# Deploy with Capistrano

group :development do

  gem 'annotate-models'
  gem 'rb-fsevent'#, :require => (RUBY_PLATFORM =~ /darwin/i)

end

group :test do
  # Pretty printed test output
  gem 'turn', :require => false
  gem 'rspec'

end

group :deployment do

Answer 1

Additionally, I'd also nuke your Gemfile.lock , and specify which version of Rails you're using in your Gemfile:

gem "rails", "3.1.0.rc4"

And then re-bundle everything by running bundle

Answer 2

For some reason, you are installing an ancient version of activerecord which is failing.

What I would do is first check your Gemfile.lock file to see what gem is specifying an old version of activerecord. (Do a search in that file.) If you can, comment out that gem which uses the old activerecord from the Gemfile or use a more modern version or replacement of that gem if you need it. (Nothing jumps out at me from a cursory examination of your Gemfile, maybe you installed some old stuff earlier and removed it?)

If you don't see version 1.6 of activerecord specified in the Gemfile.lock , I'd blow up your rvm gemset and install again from the command line. You probably have some old stuff in there for whatever reason. In your project directory use the following commands:

$ rvm gemset empty rails31

$ rvm gemset use rails31

$ gem install bundler

$ bundle install

Good luck!
