我已经通过MacPorts在Mac OS X 10.9上安装了sbt。 如果我以root身份运行sbt - 一切正常，但作为用户 - 我有一个例外。

〜/ .sbt / *〜/ .ivy2 / *归我的用户所有 / opt / local / share / sbt - sbt脚本和sbt-launch.jar所在的文件具有777权限。

似乎sbt想要在某处创建文件而失败，如果你不知道这方面的确切解决方案，请告知我该如何调试。是否有可能看到一些sbt日志，或者可能有一些系统工具来定义sbt想要创建文件的位置。

谢谢你的建议。

此问题的一个原因可能是您以root身份运行sbt :)。当你这样做时，sbt以root身份在你的目录中创建了东西（比如目标目录），现在它们归root所有。当您重新运行sbt时，您将无法再访问这些目录。

您现在要么必须修复所有目录/文件所有权/权限，要么全部删除它们。当您从帐户重新运行sbt时，它会在您的帐户下重新创建这些目录/文件，并且它会起作用。

如果您正在使用git repo工作，只需重新克隆项目并重新运行sbt，而不是root。
