Question

我看到其他人也有类似的问题，但没有一个解决方案对我有用。 0.3.14 gem存在于其他gem文件中。我完全按照此处的说明完成了所有事情：https://github.com/brianmario/mysql2。我仍然得到以下内容。我不知道为什么安装程序指示它找不到包含目录，因为我已经检查过并且它存在。 thread.h文件存在，但不存在于ruby目录中。而是它在这里：C：\ RailsInstaller \ DevKit \ lib \ perl5 \ 5.8 \ msys \ CORE \

我正在运行Windows 7并尝试在Aptana 3中构建我的rails项目。我的Ruby是1.9.3。

还试过这个：

$ gem install mysql2 --platform=ruby -- '--with-mysql-lib="C:\MySQL-Connector-C-6.1\lib" --with-mysql-include="C:\MySQL-Connector-C-6.1
\include" --with-mysql-dir="C:\MySQL-Connector-C-6.1"'

另一种建议配置：

$ gem install mysql2 -v 0.3.14 -- '--with-mysql-config="C:\wamp\bin\mysql\mysql5.5.24\bin"'

为了清楚起见，我在此处删除了冗余配置选项。请注意，此尝试生成了权限被拒绝错误。

我发现了问题！这就是问题所在。说明说将libmysql.dll文件复制到ruby主目录。需要复制的文件不是.dll - 它是libmysql.lib文件（或两者）。我复制了它，它编译得很好。耶！
