相对流浪者和Ruby newb在这里。我正在尝试启用从我的Windows机器到我的Vagrant创建的Ubuntu VM的SSH转发。我的Vagrantfile有一些Virtualbox提供程序特定的配置：
config.vm.provider "virtualbox" do |v|
v.name = guestHostname
v.memory = 8192
v.cpus = 2
v.customize ["modifyvm", :id, "--vram", "128"]
v.gui = true
end
本身工作正常。但是当我添加 SSH 转发的配置时：
config.ssh.forward_agent = true
运行"vagrant up"开始失败，并显示以下错误消息：

注释掉特定于提供程序的配置会使错误消失，并且转发似乎有效。关于可能导致问题的原因的任何想法？
我可以看到您使用的是流浪者 1.9.4，这是流浪者 1.9.4 的已知问题。我在这里链接了与此问题相关的 github 问题。不过，这已在 1.9.5 版中修复。因此，您可以降级到1.9.3或升级到1.9.5
