Question

I’ve been tinkering with this one for several days and I still get the same error. For starters, I have been able to start a newly rails app with sqlite as the database but the application we are working on uses Mysql. So when I go to the app directory and type “rails server” it gives me the following:

 /Users/gojinjedi/.rvm/gems/ruby-1.9.2-p180@rails3/gems/mysql2-0.2.7/lib/mysql2.rb:8:in `require': dlopen(/Users/gojinjedi/.rvm/gems/ruby-1.9.2-p180@rails3/gems/mysql2-0.2.7/lib/mysql2/mysql2.bundle, 9): Library not loaded: libmysqlclient.18.dylib (LoadError)

So (I think) MySQL development headers aren’t installed, which I googled everywhere how to install them and tried most install command line to no success yet. Examples of commands I’ve tried:

gem install mysql2

sudo env ARCHFLAGS="-arch i386" gem install mysql --   --with-mysql-dir=/usr/local/mysql --with-mysql-lib=/usr/local/mysql/lib   --with-mysql-include=/usr/local/mysql/include

I did the bundle install, bundle update and bundle commands in the app directory…I’m running out of options…can you help me?

I’m on mac osx 10.7

Answer 1

have you tried something like this, I’m one Mac OS X (lion) too and I have no problem with the mysql gem. Or may be you can find what you want here

[EDIT]

Or you can simply use ruby-mysql gem for development environment
