Installed Ruby on Rails but when I try to run Rails Sever it doesn't load WEBrick?

I installed Ruby on Rails on my mac today along with Gems and MYsql. I'm trying to follow the lynda.com tutorial and I've run into a brick wall. When I try to run the rails server it doesnt load WEBrick for some reason. This is the error I get:

Any ideas on what I could do? Please help - I'm stuck!

I did rails -v and I'm on 3.0.5:

rails -v
/Library/Ruby/Gems/1.8/gems/railties-3.0.5/lib/rails/script_rails_loader.rb:11: warning: Insecure world writable dir /usr/local in PATH, mode 040777
/Library/Ruby/Gems/1.8/gems/bundler-1.0.10/lib/bundler/runtime.rb:136: warning: Insecure world writable dir /usr/local in PATH, mode 040777
Rails 3.0.5

BTW: I tried to go and do this sudo chmod go-w /usr/local/bin but this did not resolve anything. Reason I did this was because of: warning: Insecure world writable dir /usr/local/bin in PATH, mode 040777


I strongly urge you to use rvm to install ruby and try again:

  • http://rvm.beginrescueend.com/

There are a number of issues with the default ruby that ships with OS X. When you install RVM, you can easily get a clean installation of ruby.

Make sure to read the install instructions carefully, especially the last bit about inserting a line into your .bashrc.

Forget the warning: Insecure world writable dir error, that's just a warning from Bundler and has nothing to do with the error that is keeping Rails from starting.

That error is due to the Mysql2 gem not loading properly. I had the same problem. Basically you need the mysql source files for the gem to compile properly. I solved it by installing Homebrew, then installing mysql with Homebrew, then running Bundle install again.

Try this:

  1. install Homebrew
  2. install mysql with hombrew: brew install mysql in a terminal
  3. delete the Gemfile.lock file inside your Rails app
  4. run 'bundle install` again
  5. try starting Rails with this command: bundle exec rails server

I know I'm a little late to this party, but I'm hoping this might help someone else.


You have to set your Gemfile and run bundle install


You do seem to have permissions issues with your gems directory. Try resolving that with:

sudo find /Library/Ruby/Gems/1.8/gems/ -type d -exec chmod 755 '{}' +
