流浪汉在Windows 10上降级到1.8.4后找不到插件

Question

在了解到我安装的Vagrant的最新版本(1.9.x)在我不得不使用的vagrant box上不能很好地工作后，我将Vagrant版本降级到1.8.5，首先卸载Vagrant，然后安装早期版本(1.8.5)。

在那之后，Vagrant变得无法使用。

$ vagrant up
Bundler, the underlying system used to manage Vagrant plugins,
is reporting that a plugin or its dependency can't be found.
This is usually caused by manual tampering with the 'plugins.json'
file in the Vagrant home directory. To fix this error, please
remove that file and reinstall all your plugins using `vagrant
plugin install`.
C:/HashiCorp/Vagrant/embedded/gems/gems/bundler1.12.5/lib/bundler/resolver.rb:356:in block in verify_gemfile_dependencies_are_found!': Could not find gem 'vagrant-vbguest x86-mingw32' in any of the gem sources listed in your Gemfile or available on this machine. (Bundler::GemNotFound)`

在我按照建议运行vagrant plugin install之后，我得到了同样的错误。该plugins.json不包含任何relevant(C:\HashiCorp\Vagrant\embedded\plugins.json)：

{
    "version": "1",
    "installed": {
        "vagrant-share": {
            "ruby_version": "0",
            "vagrant_version": "1.8.5"
        }
    }
}

我还注意到我没有~/.van rant.d目录。有人知道这是怎么回事吗？我又试了几次重新安装流浪汉，每次都是同样的错误。
