正如我所说，我的系统上一切都在运行，但当我将代码推送到服务器时(我用一个新的更新代码目录替换我的应用程序目录，并在settings.py文件中的installeddapp中手动添加"taggit"(，之后运行所有所需的cmd，然后我运行"；sudo服务apache2重新加载"；。我得到500内部服务器错误。
我读了很多解决方案，但没有什么对我有效。当我撤销更改时，一切都很好。网站上线了。
我使用pip安装一个taggit模块，如下所示：
Defaulting to user installation because normal site-packages is not writeable
Requirement already satisfied: django-taggit in ./.local/lib/python3.6/site-packages (1.3.0)
Requirement already satisfied: Django>=1.11 in /usr/local/lib/python3.6/dist-packages (from django-taggit) (3.0.7)
Requirement already satisfied: asgiref~=3.2 in /usr/local/lib/python3.6/dist-packages (from Django>=1.11->django-taggit) (3.2.10)
Requirement already satisfied: pytz in /usr/local/lib/python3.6/dist-packages (from Django>=1.11->django-taggit) (2020.1)
Requirement already satisfied: sqlparse>=0.2.2 in /usr/local/lib/python3.6/dist-packages (from Django>=1.11->django-taggit) (0.3.1)
然后我尝试从shell导入模块。它被导入：

这就是我如何配置Apache附加的Apache配置文件。Apache服务器配置文件。
我是新来的或第一次问是否需要更多信息，请告诉我。
Update1:我想明确我没有使用虚拟环境；django脆型；它运行良好。我不明白为什么它找不到"；塔吉特"；模块，如果它可以以同样的方式使用django-crisp形式。
任何建议都会有所帮助。Update2:当我在python shell中检查sys.path时，我发现了一些问题。我没有得到我的项目路径，但在manage.py shell中，我的项目道路在那里，这有一定的意义吗。

我仍然不明白为什么django不能从我的主系统环境中导入taggit，但我知道它是如何工作的。
我将taggit安装在我的django项目目录(/mysite(中，以便django可以使用以下命令从那里访问taggit。
ubuntu@ip-172-31-35-150:/var/www/mysite$ sudo python3 -m pip install --target=/var/www/mysite django-taggit

然后我只需重新加载apache服务器，它就可以正常工作了。这不是使用这样的模块的好方法，因为它在我的目录中创建了很多额外的文件，但目前还可以。
如果我提出了确切的解决方案，我会在这里更新。
