I have just upgraded installed rails 1.1 using gem. I have set up a rails app using radrails. I have set up one model for testing and set up one migration in order to create the table for that model. When I type rake migrate I get the following error message. rake aborted! uninitialized constant WEBrick (See full trace by running task with --trace) I have attached the trace below. This happens both on windows and Centos 4.2. I am using mysql 4.x. Anybody have a clue? ** Invoke migrate (first_time) ** Invoke db:migrate (first_time) ** Invoke environment (first_time) ** Execute environment rake aborted! uninitialized constant WEBrick /usr/lib/ruby/gems/1.8/gems/activesupport-1.3.1/lib/active_support/dependencies.rb:123:in `const_missing'' /usr/lib/ruby/gems/1.8/gems/activesupport-1.3.1/lib/active_support/dependencies.rb:131:in `const_missing'' /root/borg/test_callflow/config/../config/environment.rb:56 /usr/lib/site_ruby/1.8/rubygems/custom_require.rb:21:in `require'' /usr/lib/ruby/gems/1.8/gems/activesupport-1.3.1/lib/active_support/dependencies.rb:147:in `require'' /usr/lib/ruby/gems/1.8/gems/rails-1.1.2/lib/tasks/misc.rake:3 /usr/lib/ruby/gems/1.8/gems/rake-0.7.1/lib/rake.rb:387:in `execute'' /usr/lib/ruby/gems/1.8/gems/rake-0.7.1/lib/rake.rb:387:in `execute'' /usr/lib/ruby/gems/1.8/gems/rake-0.7.1/lib/rake.rb:357:in `invoke'' /usr/lib/ruby/1.8/thread.rb:135:in `synchronize'' /usr/lib/ruby/gems/1.8/gems/rake-0.7.1/lib/rake.rb:350:in `invoke'' /usr/lib/ruby/gems/1.8/gems/rake-0.7.1/lib/rake.rb:364:in `invoke_prerequisites'' /usr/lib/ruby/gems/1.8/gems/rake-0.7.1/lib/rake.rb:999:in `each'' /usr/lib/ruby/gems/1.8/gems/rake-0.7.1/lib/rake.rb:363:in `invoke_prerequisites'' /usr/lib/ruby/gems/1.8/gems/rake-0.7.1/lib/rake.rb:356:in `invoke'' /usr/lib/ruby/1.8/thread.rb:135:in `synchronize'' /usr/lib/ruby/gems/1.8/gems/rake-0.7.1/lib/rake.rb:350:in `invoke'' /usr/lib/ruby/gems/1.8/gems/rake-0.7.1/lib/rake.rb:364:in `invoke_prerequisites'' /usr/lib/ruby/gems/1.8/gems/rake-0.7.1/lib/rake.rb:999:in `each'' /usr/lib/ruby/gems/1.8/gems/rake-0.7.1/lib/rake.rb:363:in `invoke_prerequisites'' /usr/lib/ruby/gems/1.8/gems/rake-0.7.1/lib/rake.rb:356:in `invoke'' /usr/lib/ruby/1.8/thread.rb:135:in `synchronize'' /usr/lib/ruby/gems/1.8/gems/rake-0.7.1/lib/rake.rb:350:in `invoke'' /usr/lib/ruby/gems/1.8/gems/rake-0.7.1/lib/rake.rb:1906:in `run'' /usr/lib/ruby/gems/1.8/gems/rake-0.7.1/lib/rake.rb:1906:in `run'' /usr/lib/ruby/gems/1.8/gems/rake-0.7.1/bin/rake:7 /usr/bin/rake:18
