Django can't import taggit module in apache server, fine in local server, Import from manage.py shell but django can't import it, No virtualenv used

Question

正如我所说的一切都在我的系统上运行，但是当我将代码推送到我的服务器时（我将我的应用程序目录替换为新的更新代码目录并在我的已安装应用程序的 settings.py 文件中手动添加“taggit”）之后运行所有需要 cmd 然后我运行“sudo service apache2 reload”。 我收到 500 内部服务器错误。

我阅读了很多解决方案，但没有什么对我有用。 当我撤消更改时，一切正常的网站都会上线。

我使用 pip 安装 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：

这就是我配置 Apache 附加 apache 配置文件的方式。 Apache 服务器配置文件。

我是新手或第一次询问是否需要更多信息，请告诉我。

Update1：我想明确表示我没有使用虚拟环境，当我安装“django-crispy-forms”时它工作正常。 如果它可以以相同的方式使用 django-crispy-forms，我不明白为什么它找不到“taggit”模块。

任何建议都会有所帮助。 Update2：当我在 python shell 中检查 sys.path 时，我想到了一些东西，但在 manage.py shell 中我的项目路径确实有意义。

Answer 1

我仍然不明白为什么 django 无法从我的主系统环境中导入 taggit，但我是如何让它工作的。

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

然后我只是重新加载 apache 服务器，它工作正常。 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，但现在还可以。

如果我想出确切的解决方案，我会在这里更新。
