Ruby On Rails 3 and Webrick issue

Question

Thanks for taking a look at this.

I started a beginner\'s tutorial on RoR through lynda.com. I followed the instructions to the letter. Everything was working so far

Answer 1

Correct way that worked for me was:

cd ~ [command]

nano .bash_profile [command]

add this line of code:

export DYLD_LIBRARY_PATH="/usr/local/mysql/lib:$DYLD_LIBRARY_PATH"

ctrl+x [save]

y [yes]

cd Sites/sitename/ [command]

rails server [run WEBrick server]

and you should get this message:

=> Booting WEBrick
=> Rails 3.2.11 application starting in development on localhost:3000
=> Call with -d to detach

Answer 2

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.

Answer 3

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!

Answer 4

I had the same problem. I simply ran the following code:

sudo ln -s /usr/local/mysql/lib/libmysqlclient.18.dylib /usr/lib

Press enter, and then run

rails server

and it worked!

Answer 5

export DYLD_LIBRARY_PATH=/usr/local/mysql/lib/

This is the code that worked for me :D
