当我启动Laravel的Homestead时，我遇到了以下错误。我以前从未遇到过运行它的问题。今天，我不得不升级Vagrant和Virtual Box。以下是完整的输出，但我会突出显示错误：

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.
默认值：检测到Vagrant不安全密钥。 Vagrant会自动更换 default：使用新生成的密钥对，以提高安全性。
==＆GT;默认：无法重启php5-fpm.service：未找到单元php5-fpm.service。
如何解决这些错误，以便Homestead像往常一样运行？我正在使用OSX。
