推荐答案
就最重要的结果而言,我应该指出,这个答案是从2年前开始的。这是一个更新的答案:如何使用mysql2在Windows 7上的Rails 3应用程序中的gem?
Since this keeps coming up on google as on of the top results, I should point out that this answers is from almost 2 years ago. Here is a more updated answer: How to use "mysql2" gem in Rails 3 application on Windows 7?
据开发人员介绍,已经报告过它的错误,他正在努力将mysql2分离到Windows。截至目前 - 它仍在工作中。
According to the developer there is a already a reported bug for it and he is working on parting mysql2 over to Windows. As of now - it's still in the works. Use the older mysql driver for now - or use sqlite for local development.
