Question

我是django的新朋友。我尝试从github上的this project开始工作。当我按照文档中的说明尝试安装python manage.py update_data时安装了要求时，就会发生此错误：

Traceback (most recent call last):
  File "/home/parsezan/work/hamclaasy-backend/env/lib/python3.6/site-packages/django/db/backends/utils.py", line 85, in _execute
    return self.cursor.execute(sql, params)
psycopg2.errors.UndefinedTable: relation "user_user" does not exist
LINE 1: SELECT (1) AS "a" FROM "user_user" WHERE "user_user"."friend...
                               ^


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

setting.py：

AUTH_USER_MODEL = 'user.User'

我只是尝试在我的Ubuntu 18.04上运行此项目。如果需要任何附件，我会做。谢谢。

我遇到了同样的错误，即文件设置中缺少逗号。py

INSTALLED_APPS = [
    'main_app',  # <--- I was missing a comma here
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
]

psycopg2.errors.UndefinedTable：关系“ user_user”不存在
