Question

我一直在寻找这个错误，重新安装所有内容，然后尝试了一下。我在这里找到的只是旧帖子和旧版本。是的，我已经下载了MySQL C Connector并将lib移动到该ruby目录。仍然没有。

我正在运行PC WINx64 Ruby版本2.0.0-p195 最新版本的DevKit

**gem install mysql2**
**Temporarily enhancing PATH to include DevKit...

我已从http://dev.mysql.com/downloads/mirror.php?id=412857

下载了连接器

并在命令提示符下输入

gem install mysql --platform = ruby - --with-mysql-include = C：\ mysql-connector-c-6.1.0-winx64 \ include --with-mysql-lib = C： \ MySQL的连接器-C-6.1.0-winx64 \ lib中

Answer 2

尝试使用以下命令安装mysql gem

gem install mysql2 -- '--with-mysql-lib="c:\Program Files\MySQL\MySQL Server 5.0\lib\opt" --with-mysql-include="c:\Program Files\MySQL\MySQL Server 5.0\include"'

注意：根据您的安装更改mysql安装目录

无法安装gem install mysql2 Ruby WINx64
