节点json2csv无输出

Question

请容忍我，我是一个全新的节点平台。

json2csv的安装方式如下：

$ npm install json2csv --save -g

尝试从命令行的网站中重新创建示例。

文件：mycars.json

跑步时：

$ json2csv -i mycars.json -f carModel,price,colors -p

它回来了，所以：

---------------------------------
| "carModel" | "price" |"colors"|
---------------------------------    
|            |         |        |
---------------------------------

鉴于预期是：

------------------------------------------------------------
| "carModel" | "price" | "colors"                          |
------------------------------------------------------------
|  "Audi"    | 0       | "[""blue"",""green"",""yellow""]" |
------------------------------------------------------------
|  "BMW"     | 15000   | "[""red"",""blue""]"              |
------------------------------------------------------------

您知道这里可能出了什么问题吗?或者有关于如何开始调试的建议吗？

Answer 1

也许你应该改变这个：

{
  "mycars": [
    {
    "carModel": "Audi",
    "price": 0,
    "colors": ["blue","green","yellow"]
  }, {
    "carModel": "BMW",
    "price": 15000,
    "colors": ["red","blue"]
  }, {
    "carModel": "Mercedes",
    "price": 20000,
    "colors": "yellow"
  }, {
    "carModel": "Porsche",
    "price": 30000,
    "colors": ["green","teal","aqua"]
  }
  ]
}

对此：

[
  {
    "carModel": "Audi",
    "price": 0,
    "colors": ["blue","green","yellow"]
  }, {
    "carModel": "BMW",
    "price": 15000,
    "colors": ["red","blue"]
  }, {
    "carModel": "Mercedes",
    "price": 20000,
    "colors": "yellow"
  }, {
    "carModel": "Porsche",
    "price": 30000,
    "colors": ["green","teal","aqua"]
  }
]

并使用正确的属性名。例如，在JSON中没有color。
