Vagrant 鲁比和流浪汉会怎么样？

我刚刚配置了一个新的WordPress项目，当我执行

vagrant up

时，我收到以下错误：

我使用的是LinuxMint19.3和Vagrant2.2.6； ruby 2.5.1p57（2018-03-29修订版63029）[x86_64-linux-gnu]

有人能帮我吗？

有一行指向你的流浪汉档案：

from /home/fabio/Vagrant/pessoasaltas.com/Vagrantfile:30:in `block in <top (required)>'

很抱歉给你起了个标题，但是没有一个建议的答案适合我的问题。至少，你需要编辑你的问题并添加你的文件。乍一看，某个地方加载的yaml文件无效。

vagrant up --debug
