玩 2.6.13 有问题 运行 Scaldi

Question

我尝试将使用 Scaldi 注入的应用程序从 Play 2.6.12 升级到 Play 2.6.13。在所有应用程序中，我们 运行 遇到了同样的问题。

它试图实例化类型为“$$anon$1”或 'play.api.inject.BindingKey$$anon@5d807417' 的对象。这个类型显然是不存在的，所以它确实会导致 Stack down 出错。

这似乎是在加载环境 class 时发生的。这里有没有人知道它可能是什么？

我 运行 遇到了完全相同的问题，发现这是由于 build.sbt (scala v2.12.6) 中升级 scala 版本引起的。 我将 scala 降级到 v2.12.4，它运行良好。
