Windows 10。

运行vagrant up时，出现以下错误：

我试图从 GitHub 问题中找到一些解决方案： https://github.com/vagrant-landrush/landrush/issues/16

不知道。

也试过安装这个：

gem install win32-process

同样的结果。

所以我不知道真正的问题。

【问题讨论】：

我有点困惑，你是想从 Windows 运行这段代码吗？因为我很确定 fork 在 Windows 上不起作用，这就是您收到此错误的原因。
@Thermatix 所以流浪汉不能在 Windows 上正常工作？
不，应该没问题，因为我之前在 windows 上使用过，您可能需要进行不同的配置。
@Thermatix 我不记得有配置的东西。只是现在不知道如何解决。
我看到你安装了vagrant-dns 插件，其他一些人报告说卸载它可以解决问题。

标签： ruby windows vagrant

【解决方案1】：

据报道，vagrant-dns 插件可能会在 Windows 上导致此问题。如果已安装，请尝试将其卸载。

如果这不是一个选项，Windows 10 具有您可以安装的适用于 Linux 的 Windows 子系统功能。这将允许您利用 Windows 商店中的 Unix Distro 应用程序之一来安装 bash shell。这将允许您在 Linux 环境中运行您的应用程序，有效地启用 Fork()
