Question

当我尝试创建Rails服务器时，这就是我得到的。它立即运行超过500行代码并返回此消息。这是我的第一个Ruby on Rails项目。我对编码也很陌生。如果可能的话，会爱一些帮助。谢谢！

Answer 1

根据 Dave Schweisguth 的答案，关于ruby bug，并执行 Heesob Park 的评论所描述的步骤，我可以让mysql2 gem工作。谢谢大家分享这个。

引自Heesob评论：

MySQL Connector / C 64位中包含的libmysql.lib不是   与mingw64-gcc编译器兼容。

您需要生成与mingw64兼容的libmysql.lib文件。

要创建兼容的libmysql.lib文件，我执行了以下步骤：（我用Ruby 2.0.0p481运行Win8.1 x64 [x64-mingw32]）

1）下载此zip文件https://structure-svm-map.googlecode.com/files/svm-map-win.zip并将其解压缩到c：\ tmp \ svm-map

2）从http://dev.mysql.com/get/Downloads/Connector-C/mysql-connector-c-6.1.3-winx64.zip下载Mysql C / Connector 6.1并将其解压缩到c：\ tmp \ mysql

3）打开CMD提示

4）cd \tmp\svm-map\python-mingw-lib

5）gendef.exe \tmp\mysql\lib\libmysql.dll

6）move libmysql.def \tmp\mysql\lib

7）cd \tmp\mysql\lib

8）\Ruby200-x64\DevKit\mingw\bin\dlltool -v --dllname libmysql.dll --def libmysql.def --output-lib libmysql.lib

9）gem install mysql2 -- --with-mysql-dir=c:\tmp\mysql

就是这样！在Windows 8.1上运行Rails x64的Mysql2 gem！ =）

Answer 2

我用google搜索“x64-mingw32 mysql2分段错误”并发现：https://bugs.ruby-lang.org/issues/8591

看起来mysql2中有一个错误。对Ruby问题的评论提供了一种解决方法，用您的编译器重新生成libmysql.lib。请回报并告知我们是否有效。

使用mingw编译mysql2时出现分段错误
