任何插件的vagrant插件安装都失败了

Question

对于任何插件运行vagrant plugin install [plugin]失败（使用管理命令提示符。）不确定问题是什么。 dev/null不在我的计算机上，它不应该尝试安装到VM。

尝试：

• 卸载Vagrant，删除.vagrant.d目录，重新安装Vagrant
• 使用嵌入式Ruby
更新Vagrant的宝石
• 更新VirtualBox
• 禁用.bashrc文件（也尝试使用Git Bash）

使用：

• Windows 7 Pro x64 SP1
• Vagrant 1.7.2
• VirtualBox 4.3.26

输出：

注意：** = C:/HashiCorp/Vagrant/embedded

检查是否有c：\ dev \ null目录（或者d：\ dev \ null等）。

初始化脚本查找/ dev / null文件但查找目录。通过删除目录一切正常（它对我来说）

似乎其他一些linux移植应用程序创建了c：\ dev \ null文件夹
