我的操作系统是 windows 7，我正准备将我的本地 MySQL 数据库连接到 Heroku 共享数据库，有一次，我得到了 libmysql.dll 文件丢失的错误，所以我搜索并下载了 dll 文件并保存它在 ruby​​/bin 目录中。当我再次连接时，这次它显示错误 ruby​​.exe 未被识别为内部或外部命令，这就是错误的样子。

最佳答案

您的 PATH 变量中没有 ruby.exe 的路径。

在 Windows 7 中，您可以通过 开始菜单 -> 右键单击​​ 我的电脑 -> 左侧最后一个选项(我认为是 高级设置) -> Environment variables -> 在 system variables 子菜单中找到 Path 双击并添加；然后是 ruby​​ 安装的 bin 文件夹的路径。这应该可以修复它(您将需要重新启动所有已启动的命令提示符)。
