我已经使用VirtualBox进行了两个星期的流浪设置，它运行正常。昨天我尝试使用vagrant并发现没有任何命令有效。它们都会导致callstack出错（在Ruby中？）。 我正在使用Windows 7和VirtualBox 4.3.12（因为我的公司环境使用BeyondTrust和4.3.12是我唯一可以使用的版本）。

我试过了：
1）重新安装流浪汉
2）重新安装VirtualBox
3）检查c：/users/scott/.vagrant.d中的权限
4）在c：/users/scott/hootenanny/.vagrant
当然，任何帮助都表示赞赏。

我删除了.NET和Windows的所有最新Microsoft安全更新，Vagrant再次开始工作。他们的日期是2016年3月24日在我的机器上。然后正如我试图了解更多，我正在重新安装更新的公司机器。我无能为力。我的公司使用的是Microsoft Windows 7 Enterprise，我真的不应该卸载他们的安全更新，因为我是工程师，而不是系统管理员。
我希望这些信息可以帮助那些盯着同一个Ruby callstack并想知道该怎么做的人。

我也通过运行Git bash作为管理员并通过提升的控制台调用vagrant来解决问题。

我遇到了同样的问题，结果发现我没有安装了VirtualBox。一旦我安装了virtualbox，这个错误消失了，并且vagrant状态按预期工作（我也在使用许多企业安全应用程序阻碍的机器，这可能就是为什么vagrant没有给我一个更有用的错误信息）。 / p>
我知道这对OP没有帮助，但我认为我会分享我在谷歌搜索到此页面之后的下一个人的经历。
