我在 Windows 上使用 RubyMine，所以我可以在 Rails 应用程序上运行给定的 ruby​​。当我单击运行时，我收到以下错误：

我对 ruby​​ 不是很熟悉，但它说明了我已经安装并添加到 PATH 变量中的“mysql”。有什么帮助吗？谢谢

您安装的 mysql gem 期望libmysql.dll您的系统中可以使用特定版本的 MySQL（当您gem install mysql在控制台中显示正确的图例时）。

mysql_api.so无法加载，因此会产生您看到的错误。

我在博客中介绍了另一种安装和编译 MySQL 组件的方法，该方法与您安装的 MySQL 版本无关。

希望有帮助。

这可能是版本问题。当我将旧的 mysql 版本与新的 mysql gem 一起使用时，我确实遇到了同样的问题。

请找到您的 mysql 服务器所需的正确 gem。
