【问题描述】：

我已使用 RVM 将我的 ruby 版本更新到 2.0.0。然后安装mysql2 gem

-> % gem install mysql2
Building native extensions.  This could take a while...
Successfully installed mysql2-0.3.13
1 gem installed
Installing ri documentation for mysql2-0.3.13...
Building YARD (yri) index for mysql2-0.3.13...
Installing RDoc documentation for mysql2-0.3.13...

之后我尝试在 irb 中要求 mysql2。但它会导致以下错误！

-> % irb
2.0.0p247 :001 > require 'mysql2'
LoadError: cannot load such file -- mysql2/mysql2

    from (irb):1
    from /home/sayuj/.rvm/rubies/ruby-2.0.0-p247/bin/irb:16:in `<main>'

我该如何解决。请帮我解决这个问题。

更新您的 RVM rvm get stable 并重新安装 ruby2
