mysql - 无法安装 gem install mysql2 Ruby WINx64

Question

我一直在寻找这个错误，重新安装一切，并尝试了一切。我在这里找到的都是旧帖子和旧版本。是的，我已经下载了 MySQL C 连接器并将库移动到那个 ruby​​ 目录。还是什么都没有。

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...

ERROR:  Error installing mysql:

我已经从 http://dev.mysql.com/downloads/mirror.php?id=412857 下载了连接器

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-connector-c-6.1.0-winx64\lib
