首先尝试使用chef-solo旋转一个流浪汉VM。现在由于我的node.json文件遇到错误，其他人尝试address on SO几个times before。 VM是Ubuntu 12.04，工作站和节点都运行10.16.2。
这是node.json：
{
"name": "apptron",
"description": "slightly complicated config",
"chef_type": "role",
"json_class": "Chef::Role",
"default_attributes": {},
"env_run_lists": {
"_default": [],
"production": [],
"staging": [],
"test": [],
"monitoring": [],
"queuing": []
},
"run_list": ["recipe[base]", "recipe[user]"],
"override_attributes": {}
}
在节点上堆栈跟踪：

答案 0 :(得分：1)
由于某种原因，当我应用此问题时，问题出现在node.json键json_class: "Chef::Role"，我得到了奇怪的错误。当我不这样做时，一切都按照Vagrant的预期运行。
答案 1 :(得分：1)
您将角色json数据放入节点json文件中，这就是导致此问题的原因。
这一位：
"chef_type": "role",
"json_class": "Chef::Role",
属于角色json。
在我的情况下，我在角色json中有节点json数据，在节点json中有角色json数据... herp derp：）
