【参考方案1】：

我想我需要回答我的问题，nomodulefounderror 的问题，因为我的 Postgres 数据库中的数据不完整。我已将 .sql 文件转储到我的经理提供的 Postgres 数据库中，然后根据数据库名称配置设置文件并运行命令 python manage.py runserver --settings=bg.settings_dev_sai。效果很好。

【参考方案2】：

您的项目目录名称似乎是'bg'，所以我认为在导入模块时应该这样做

from bg import settings_dev_sai

或

from bg.settings_dev_sai import *

还要确保 settings_dev_sai 在同一目录中 'bg'

【讨论】：

嗨，@NitinGavai 感谢您回答我的问题。我确实尝试在设置文件中添加 bg.settings_dev_sai 。但它让我导入错误。我已经上传了错误日志。请看一次，让我知道该怎么做。先生

你试过python manage.py runserver --settings=bg.settings_dev_sai吗？

是的，我确实尝试使用该服务器运行。但发生了同样的错误

【参考方案3】：

我认为你只需要运行它

python manage.py runserver --settings=bridge.settings_dev_sai

因为 bridge.settings 是一个文件而不是一个包

【讨论】：

嗨@Cauane。我尝试运行 python manage.py runserver。它把我扔了ImportError: no module named settings_dev_sai。我不知道为什么会出现这个错误
