Windows 7 中的“ruby.exe 未被识别为内部或外部命令”

Question

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，在某个时间点，我得到了错误libmysql.dll文件丢失，所以我搜索并下载了dll文件并保存它在 ruby​​/bin 目录中。再次，当我要连接时，这一次它显示错误 ruby​​.exe 无法识别为内部或外部命令，这就是错误的外观。

您的 PATH 变量中没有 ruby.exe 的路径。

在 Windows 7 中，您可以通过 Start menu 设置它 -> 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（您需要重新启动已启动的所有命令提示符）。
