在服务器上添加夹具时出现反序列化错误loaddata

问题描述

我正在尝试将我的数据添加到我服务器的数据库中。我在我的本地机器上使用完全相同的 JSON 文件并且它工作正常。但是当我在服务器上做同样的事情时，它给了我 Deserialization Error。

JSON 文件太大，我无法在此处显示，但我确定没有错别字。

我完成了所有迁移和数据库工作 - 我可以从管理仪表板添加对象。我该如何解决这个错误？

我得到的错误：

    Traceback (most recent call last):
  File "/home/testuser/myprojectt/myvenv/lib/python3.8/site-packages/django/core/serializers/json.py",line 69,in Deserializer
    objects = json.loads(stream_or_string)
  File "/usr/lib/python3.8/json/__init__.py",line 357,in loads
    return _default_decoder.decode(s)
  File "/usr/lib/python3.8/json/decoder.py",line 337,in decode
    obj,end = self.raw_decode(s,idx=_w(s,0).end())
  File "/usr/lib/python3.8/json/decoder.py",line 355,in raw_decode
    raise JSONDecodeError("Expecting value",s,err.value) from None
json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)

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

一次又一次地检查 JSON 但它仍然可以在本地运行但在服务器上出现相同的错误。

解决方法

我在服务器上使用 Ubuntu。并且没有安装 git-lfs。要解决此问题：

1. 使用 sudo apt-get install git-lfs 安装它。

2. 然后在项目目录上运行 git lfs pull。

然后我设法根据需要处理 JSON 数据。
