我到处寻找解决方案，发现了一些对其他人有用的东西，但在这种情况下却行不通。我尝试了以下方法:

1. 添加行 project/play-fork-run.sbt到 .gitignore文件。
2. 删除文件play-fork-run.sbt .
3. 将这些解析器添加到 build.stb文件:
resolvers += Resolver.url("Typesafe Ivy", url("<a href="http://repo.typesafe.com/typesafe/ivy-snapshots" rel="noreferrer noopener nofollow">http://repo.typesafe.com/typesafe/ivy-snapshots</a>"))(Resolver.ivyStylePatterns)
resolvers += "Typesafe" at "<a href="http://repo.typesafe.com/typesafe/releases/" rel="noreferrer noopener nofollow">http://repo.typesafe.com/typesafe/releases/</a>"


但似乎没有任何效果，当我在本地主机上编译并运行该应用程序时，它运行良好。

有解决这个问题的想法吗？

非常感谢任何帮助!

谢谢

这在 localhost 上起作用的原因是您可能在某个时候运行了 activator，它将有问题的依赖项下载到您的本地 .ivy2 缓存中。但在 Heorku 上，只有 sbt 运行，并且激活器中存在一个长期未修复的主要错误，导致激活器和 sbt 之间的解析器不同。

听起来您已经看过这些报告，其中包含一些建议(大部分是您已经尝试过的):

• https://github.com/typesafehub/activator/issues/979
• https://github.com/typesafehub/activator/issues/1058
• https://github.com/typesafehub/activator/issues/1057
• https://github.com/typesafehub/activator/issues/1036

潜在的问题是对此的依赖:

addSbtPlugin("com.typesafe.play" % "sbt-fork-run-plugin" % "2.4.3")

仔细检查 project/ 下的所有 sbt 文件，确保其中没有任何依赖项。在推送到 Heroku 之前，还要确保您的 Git 存储库更改已提交。

最后，如果您仍然卡住了，您可以切换到使用 sbt-heroku plugin ，它使用本地编译的 Assets 并将它们部署到 Heroku。这将一起避免这个问题。

此外，我建议您在 Play mailing list 上提出这个问题.这是一个长期存在的问题，我遇到过很多人遇到过这个问题。 Typesafe 的工作人员需要听取用户的意见，了解这种情况有多猖獗。
