我正在运行 Mac OS X Yosemite，我正在按照本教程在 vagrant 上设置 dokku。

首先我通过 vagrant 安装brew install vagrant，然后按照说明进行操作。在步骤：
vagrant up
我收到超时错误：

Timed out while waiting for the machine to boot. This means that
Vagrant was unable to communicate with the guest machine within
the configured ("config.vm.boot_timeout" value) time period.
If you look above, you should be able to see the error(s) that
Vagrant had when attempting to connect to the machine. These errors
are usually good hints as to what may be wrong.
If you're using a custom box, make sure that networking is properly
working and you're able to connect to the machine. It is a common
problem that networking isn't setup properly in these boxes.
Verify that authentication configurations are also setup properly,
as well.
If the box appears to be booting properly, you may want to increase
the timeout ("config.vm.boot_timeout") value.
我再次尝试vagrant up，经过一些设置后，我收到了这个错误：

The SSH command responded with a non-zero exit status. Vagrant
assumes that this means the command failed. The output for this command
should be in the log above. Please read the output to determine what
went wrong.
有任何想法吗？
也许那个教程有点过时了......
