Question

我一直很难让rails 3.2与mysql2一起使用。
我正在运行OSX 10.6，MySQL 5.1.37

我正在获得这个可爱的堆栈跟踪。

Answer 1

rvm reset

然后运行

bundle install

帮我解决了这个问题：）

Answer 2

试

rvm reset

我只是有一个类似的错误

Answer 3

我也遇到了这个错误，我的搜索提出了这个帖子。

在我的特定实例中，我遇到了分段错误，但只有在向数据库发布更新状态时才会出现。

到目前为止注意到它正在修复它并且很好地成为一个IT人员我只读了一本手册并且谷歌不能提出答案。

mysql-2.8.1-x86-mingw32文档提到了以下内容

关于不兼容的MySQL版本的警告

混合使用MySQL版本会产生分段错误。

针对不同版本运行此gem的二进制版本   MySQL共享库libMySQL.dll将生成分段错误   并终止您的申请。

深入研究我发现“针对MySQL 5.0.83构建的二进制版本” 但是我正在运行5.1.37 -_-所以我必须找到更新的API或降级我的mysql数据库服务器以查看是否能解决问题。

我还没有解决问题，但这可能对您有用，也可能没有用，但由于我没有在其他文章中看到这一点，我认为我应该分享我的“启示录”。

更新：嗯好吧我决定更新mysql api并且他们已经对它进行了一些关键的更改，至少它在启动时如果它不兼容就会犯错误。 “MySQL客户端库版本不正确！这个gem是为6.0.0编译的，但客户端库是5.1.37。（RuntimeError）” 6.0.0让我很奇怪但是对mysql网站来说还不错，但是嘿，mysql网站上没有提到6.0.0。

好吧我的开发环境有点过时，但我会在哪里获得客户端版本6？ nvm最后一个问题：http://dev.mysql.com/downloads/connector/c/

Anonther更新：好吧看起来像至少为我固定它。确保你的connector / c版本与mysql api的版本匹配。我安装了6.0.0，没有更多的分段错误。因为当前是6.0.2，所以你仍然可以获得6.0.0，但这里只有一个链接http://mirror.services.wisc.edu/mysql/Downloads/Connector-C/ 或者您安装了连接器的匹配版本（不必匹配您的DBserver版本）

Answer 4

我在Ruby 1.9.3p125中遇到了很多分段错误错误，你试过用Ruby 1.9.3p0运行吗？遇到这类问题后我又回去了。如果p0有效，则在ruby跟踪器上提出问题单。

Answer 5

在启动ruby之前执行此命令：

export RUBYOPT="-r openssl"

Answer 6

以上错误主要是由于ruby和rails的升级。当我将我的ruby版本升级到2.0并将版本转换为4.0时，我遇到了这个问题。使用旧版本的项目面临这类问题，因为这些宝石是由旧版本的ruby编译的。它首先显示mysql2的错误，并继续为其他宝石继续。解决方案是卸载导致错误的gem并将其安装回来。顺便说一句，宝石的编译版本中的不匹配得到纠正，现在它将起作用。

您需要为导致问题的所有宝石重复此过程，直到您能够运行服务器。

Answer 7

我遇到了这个问题并且rbenv rehash修复了它。

MySQL2 / Ruby 1.9.3 / Rails上的分段错误3.2
