运行 ruby​​ 应用程序时出现问题

Question

我在 Windows 上使用 RubyMine，这样我就可以在 Rails 应用程序上运行给定的 Ruby。当我单击“运行”时，出现以下错误：

我不太熟悉 ruby​​，但它说了一些有关我已安装并添加到 PATH 变量中的“mysql”的内容。 有什么帮助吗？谢谢

Answer 1

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

mysql_api.so 无法加载，因此生成您所看到的错误。

我在博客中介绍了一种独立于您安装的 MySQL 版本来安装和编译 MySQL 组件的替代方法。

希望有帮助。

Answer 2

这应该是版本问题。当我使用旧的 mysql 版本和新的 mysql gem 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。
