警告：已初始化常量VM_BOX

Question

当我做vagrant up时看到此消息：

/path/to/Vagrantfile:3: warning: already initialized constant VM_BOX
/path/to/Vagrantfile:3: warning: previous definition of VM_BOX was here
/path/to/Vagrantfile:4: warning: already initialized constant NETWORK
/path/to/Vagrantfile:4: warning: previous definition of NETWORK was here
/path/to/Vagrantfile:5: warning: already initialized constant GUEST_PORT
/path/to/Vagrantfile:5: warning: previous definition of GUEST_PORT was here
/path/to/Vagrantfile:6: warning: already initialized constant HOST_PORT
/path/to/Vagrantfile:6: warning: previous definition of HOST_PORT was here

您只是忽略这些吗？

这些先前的定义来自哪里？据我所知，这是我第一次在这台计算机上运行Vagrant。

更新

每当我执行vagrant ssh时，我也会收到这些警告。
