"ruby.exe is not recognized as an internal or external command" in windows 7
提问by joar
My os is windows 7 and I was about to connect my localhost MySQL database with the Heroku shared database, in one point of time, I got the error libmysql.dll file missing, so I searched and downloaded the dll file and saved it in ruby/bin directory. Again when I was about to connect, this time it shows the error ruby.exe is not recognized as an internal or external command this is how the error looks.
我的操作系统是windows 7，我正准备将我的localhost MySQL数据库与Heroku共享数据库连接起来，有一次，我发现错误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。再次当我要连接时，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。

You don't have the ruby.exe's path in your PATH variable.
您ruby.exe的 PATH 变量中没有's 路径。
In windows 7 you can set it by Start menu-> right click My computer-> last option on the left (I think it was advanced settings) -> Environment variables -> in system variablessub menu find Pathdouble click it and add ; then the path to the bin folder of your ruby installation. This should fix it (you will need to restart all command prompts you have launched).
在Windows 7中，您可以通过Start menu->右键单击My computer->左侧的最后一个选项（我认为是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。这应该可以解决它（您需要重新启动您启动的所有命令提示符）。
