我正在尝试将我的开发数据库装置导入我的生产服务器。迁移已经完成，我尝试将数据库迁移精简到只有两个类。这是我收到的命令和错误：

错误

(env) root@django-01:/home/projects/server/mysite# python3 local.py loaddata db.json
Traceback (most recent call last):
  File "/home/projects/server/env/lib/python3.5/site-packages/django/core/serializers/json.py", line 68, in Deserializer
    objects = json.loads(stream_or_string)

    return _default_decoder.decode(s)

    raise JSONDecodeError("Expecting value", s, err.value) from None
json.decoder.JSONDecodeError: Expecting value: line 19 column 1 (char 229)

The above exception was the direct cause of the following exception:

【解决方案1】：

您需要使用正确的 json 格式，从您的 json 中删除最后一个 (,)

[
  {
    "model": "memberships.benefit",
    "pk": 1,
    "fields": {
      "name": "SSL Certificate"
    }
  },
  {
    "model": "memberships.benefit",
    "pk": 2,
    "fields": {
      "name": "No cancellation fee"
    }
  }
]
