虽然我已连接到互联网，但仍收到以下错误。有什么想法吗？

非常感谢您的帮助!

编辑:我在尝试运行“activator run”和“activatorcompile”时遇到了同样的错误。

我知道这个问题是针对 play 2.4 的，但我在 play 2.5 中遇到了类似的错误(特别是它无法解决旋转的部分)

在play 2.5中，支持的最新scala版本是2.11.11，因此如果您使用的是scala版本2.12，则应将其更改为2.11。

在 build.sbt 中:

scalaVersion := "2.11.11"

之后，在 sbt 中，我输入 reload ，然后输入 compile ，一切又恢复正常
