谢谢大家！

【问题讨论】：

你安装了 libmysqlclient 吗？
是的，它已经安装好了。在我的 mysql/lib 文件夹中，我可以找到 libmysqlclient.18.dylib
请正确格式化代码。
我解决了！谢谢大家。
我觉得这个SA帖子有更好的解决方案：stackoverflow.com/questions/6596303/…

【解决方案1】：

我通过使用 /usr/local/bin/mine 命令在终端中打开我的项目解决了这个问题。例如

mine .

由于某种原因，RubyMine 使用的环境与仅从命令行运行“rake test”时使用的环境不同（即使它使用正确的 .rvm 版本）。

【讨论】：

谢谢。而这个问题在 Rubymine 4.5 中仍然没有解决。
我仍然在 Ruby 6 中看到它，尽管为 DYLD_LIBRARY_PATH 添加了显式环境变量（在 shell 中可以很好地工作）
