Ruby On Rails 3 and Webrick issue?

Run these at the terminal: gem install bundler bundle And then you should be able to boot the server Edit : You should really look into using rvm to manage your ruby installs and gemsets. It'll save you a lot of time and effort in installing them too.

I ran into the same problem as you (also attempting to go through the Lynda course), and also being a newbie I got pretty frustrated pretty quickly. Buuuuut, after some searching, I found and answer here I got it to work. First, I installed the 32-bit version of MySQL, as opposed to the 64-bit version, but I'm not sure if that made a difference.

Then, uninstall the Mysql gem gem uninstall mysql2 then reinstall it sudo gem install mysql2 and finally sudo install_name_tool -change libmysqlclient.18. Dylib /usr/local/mysql/lib/libmysqlclient.18. Dylib /Library/Ruby/Gems/1.8/gems/mysql2-0.2.7/lib/mysql2/mysql2.

Bundle and you should be good to go! Worked for me anyways. Good luck!

Export DYLD_LIBRARY_PATH=/usr/local/mysql/lib/ This is the code that worked for me :D.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
