`require': cannot load such file — mysql(LoadError)

Question

when I use mysql in ruby script occurred LoadError.the detail info is below:

/System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/rubygems/core_ext/kernel_require.rb:55:in `require': cannot load such file -- mysql (LoadError)
from /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/rubygems/core_ext/kernel_require.rb:55:in `require'
from data.rb:3:in `<main>'

I have installed mysql2 (0.3.17) gem. And I use this script to build my ruby environment.

Answer 1

If you're using the mysql2 gem, you need to

require 'mysql2'

instead of

require 'mysql'

which would work if you'd installed the mysql gem.
