我遇到同样的问题，我卸载vagrant，改名为C：\ Users \％USER％\ .vagrant.d复制到.vagrant.d.bak，然后重新安装。这似乎解决了这个问题。

I like to use git bash instead of windows command prompt.

I've just installed vagrant and Vbox.

When I vagrant init in git bash I get

d:\Program Files\Vagrant\embedded\bin\ruby.exe: No such file or directory -- d:/ Program/lib/vagrant/pre-rubygems.rb (LoadError)

When I call the command in command prompt it works, I'm trying to tear myself away from guis im quite new to CLIs

anyone know whats up?

I was having the same problem, I uninstalled vagrant, renamed C:\Users\%USER%\.vagrant.d to .vagrant.d.bak, and then reinstalled. That seems to have solved the issue.
