迁移数据库从克隆的django项目到postgresql db有问题。

os是ubuntu服务器18.04

安装了python3-pip python3-dev libpq-dev postgresql postgresql-contrib nginx。

设置postgresql db，升级pip3，安装virtualenv，创建/ opt / projectdir。

在projectdir内部创建virtualenv moviesenv并激活它，用pip创建目录电影安装django，gunicorn和psycopg2，然后在目录电影内输入：git clone https://username/reponame。设置允许主机和数据库部分。键入manage.py makemigrations和recive错误消息psycopg2.ProgrammingError：关系“movie_movie”不存在django.db.utils.ProgrammingError：关系“movie_movie”不存在

这只是一小段错误输出，但我不想在这里粘贴。如果有人可以帮忙请。

好的，这里完整的追溯

Traceback (most recent call last):

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

答案

正如@Alasdair所提到的，你想从一个不存在的表中进行查询似乎是一个查询问题。这是你可以尝试解决问题的related link。它发生在： File "/opt/myproject/MovieHunter/movie/search_index.py", line 16, in __load_data_from_db for movie in Movie.objects.all():
