Windows 7中“ruby.exe未被识别为内部或外部命令”
我的操作系统是Windows 7，我正准备将我的localhost MySQL数据库与Heroku共享数据库连接，在一个时间点，我收到错误的libmysql.dll文件丢失，所以我搜索并下载了dll文件并将其保存在ruby中/ bin目录。 当我即将连接时，这次它显示错误ruby.exe未被识别为内部或外部命令这是错误的外观。

您的PATH变量中没有ruby.exe的路径。
在Windows 7中你可以通过Start menu设置它 – >右键单击My computer – >左边的最后一个选项（我认为它是advanced settings ） – >环境变量 – >在system variables子菜单中找到Path双击它并添加; 然后是ruby安装的bin文件夹的路径。 这应该修复它（您需要重新启动所有已启动的命令提示）。
