'staticfiles' 不是注册标签库：这些解决方案不起作用

Question

我是 Heroku 和 Django 的新手。
现在我正在使用 Python 开始使用 Heroku 。
当我访问https://(...secret...)-app-123.herokuapp.com/db ，
我收到以下错误：

'staticfiles' is not a registered tag library. Must be one of:
admin_list
admin_modify
admin_urls
cache
i18n
l10n
log
static
tz

然后我找到了这些解决方案。
但是，这些解决方案并不能解决我的问题。

首先，我改变了

{% load staticfiles %}

到

{% load static %}

...在db.html 。

它给了我：

run python manage.py migrate
Running python manage.py migrate on ⬢ (...secret...)-app-123... up, run.3361 (Free)
Operations to perform:
  Apply all migrations: admin, auth, contenttypes, hello, sessions
Running migrations:
  No migrations to apply.
  Your models have changes that are not yet reflected in a migration, and so won't be applied.
  Run 'manage.py makemigrations' to make new migrations, and then re-run 'manage.py migrate' to apply them.

由于错误消息告诉我运行manage.py makemigrations ，我运行：

manage.py makemigrations
Traceback (most recent call last):
  File "C:\Users\xxxxx\python-getting-started\manage.py", line 8, in ?
    from django.core.management import execute_from_command_line
ImportError: No module named django.core.management

没有模块？
Django 安装在我的机器上。
我不知道该怎么办，所以我在本地机器上更新了 Django：

C:\Users\xxxxx\python-getting-started>pip install django --upgrade
Requirement already up-to-date: django in c:\users\xxxxx\appdata\local\packages\pythonsoftwarefoundation.python.3.8_qbz5n2kfra8p0\localcache\local-packages\python38\site-packages (3.1.2)
Requirement already satisfied, skipping upgrade: sqlparse>=0.2.2 in c:\users\xxxxx\appdata\local\packages\pythonsoftwarefoundation.python.3.8_qbz5n2kfra8p0\localcache\local-packages\python38\site-packages (from django) (0.4.1)
Requirement already satisfied, skipping upgrade: pytz in c:\users\xxxxx\appdata\local\packages\pythonsoftwarefoundation.python.3.8_qbz5n2kfra8p0\localcache\local-packages\python38\site-packages (from django) (2020.1)
Requirement already satisfied, skipping upgrade: asgiref~=3.2.10 in c:\users\xxxxx\appdata\local\packages\pythonsoftwarefoundation.python.3.8_qbz5n2kfra8p0\localcache\local-packages\python38\site-packages (from django) (3.2.10)

......但是，它并没有解决我的问题。

我还补充道：

STATIC_URL = '/static/'
STATICFILES_DIRS = [os.path.join(BASE_DIR, 'static')]
VENV_PATH = os.path.dirname(BASE_DIR)
STATIC_ROOT = os.path.join(VENV_PATH, 'static_root')

在settings.py的末尾，但它也不起作用。

我还可以做些什么？

对于您的信息，到目前为止，在使用 Python 开始 Heroku 上还没有任何错误。
如果您有任何错误，您甚至无法到达这里。

请随意询问我的设置，输入这个，输入那个等等。提前谢谢你。

您应该使用虚拟环境。 在虚拟环境中管理 django 项目会更容易。
