Windows 10 mysql2 gem在Windows 10和Rails 5上运行时遇到问题

此外，我安装了msys并将其添加到路径中，它具有所需的所有工具

我下载了mysql-connector-c-6.1.3-winx64.zip并将其解压缩到目录c:\MySQLConnector中

然后我做了：

OS: Windows 10
Rails 5.1.3
Ruby 2.4.1 (x64)

gem uninstall mysql2

并卸载了所有mysql2版本

然后我做了：

OS: Windows 10
Rails 5.1.3
Ruby 2.4.1 (x64)

gem uninstall mysql2

它已完成，没有错误消息

这是我的GEM文件中的内容：

cd c:\MySQLConnector\lib
rm libmysql.def
rm libmysql.lib
gendef.exe libmysql.dll
dlltool -v --dllname libmysql.dll --def libmysql.def --output-lib libmysql.lib
rm C:\Ruby24-x64\bin\libmysql.dll
rm C:\Ruby24-x64\bin\libmysql.lib
copy libmysql.dll C:\Ruby24-x64\bin
copy libmysql.lib C:\Ruby24-x64\bin
gem install mysql2 --platform=ruby -- '--with-mysql-dir="C:/MySQLConnector"'

然后

我将收到以下错误消息：

还有人使用Windows10、Rails 5和Mysql2吗
