流浪错误apache2无法启动服务：执行＆＃39; /etc/init.d/apache2 start＆＃39;

Question

我只是正常工作，重新启动流浪汉，这发生了：

==> default: Error: /Stage[main]/Apache::Service/Service[httpd]: Failed to call refresh: Could not start Service[httpd]: Execution of '/etc/init.d/apache2 start' returned 1: 
==> default: Error: /Stage[main]/Apache::Service/Service[httpd]: Could not start Service[httpd]: Execution of '/etc/init.d/apache2 start' returned 1: 

我尝试重新安装apache2和vagrant然后它显示相同的错误。
