如何使用 django-mysql 在 Django 中修复应用程序尚未加载的错误？

Question

尝试在 pycharm 中启动 Django 时出现此错误。我不明白，因为它昨天运行正常。

django.core.exceptions.AppRegistryNotReady: Apps aren't loaded yet.

这是完整的追溯：

Traceback (most recent call last):
  File "/Users/matthew/PycharmProjects/GluIQ/DreamIt/views.py", line 2, in <module>
    from Home.models import QuestionAwner, userProject, Files
  File "/Users/matthew/PycharmProjects/GluIQ/Home/models.py", line 4, in <module>
    from django_mysql.models import JSONField
  File "/Users/matthew/python3venv/gluiq/lib/python3.7/site-packages/django_mysql/models/__init__.py", line 7, in <module>
    from django_mysql.models.base import Model  # noqa
  File "/Users/matthew/python3venv/gluiq/lib/python3.7/site-packages/django_mysql/models/base.py", line 11, in <module>
    class Model(models.Model):
  File "/Users/matthew/python3venv/gluiq/lib/python3.7/site-packages/django/db/models/base.py", line 110, in __new__
    app_config = apps.get_containing_app_config(module)
  File "/Users/matthew/python3venv/gluiq/lib/python3.7/site-packages/django/apps/registry.py", line 247, in get_containing_app_config
    self.check_apps_ready()
  File "/Users/matthew/python3venv/gluiq/lib/python3.7/site-packages/django/apps/registry.py", line 125, in check_apps_ready
    raise AppRegistryNotReady("Apps aren't loaded yet.")
django.core.exceptions.AppRegistryNotReady: Apps aren't loaded yet.

这里是 views.py 的导入：

from django.shortcuts import render, redirect
from Home.models import QuestionAwner, userProject, Files
from django.views.generic import View
from DreamIt.forms import ProjectMandateForm, StatementOfNeedForm
from braces.views import LoginRequiredMixin
from django.core.files.storage import FileSystemStorage

这里是 models.py 的导入：

from django.db import models
from django.conf import settings
from django.core.urlresolvers import reverse
from django_mysql.models import JSONField

这是我安装的应用程序：

INSTALLED_APPS = [
    'Home.apps.HomeConfig',
    'DreamIt.apps.DreamitConfig',
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'django_mysql',
]

这是我安装的：

django==1.11.20
PyMySQL==0.9.3
coverage==4.5.2
django-bootstrap3-datetimepicker==2.2.3
django-braces==1.13.0
django-mysql==2.4.1
mysql-connector-python==8.0.15
pip==10.0.1
protobuf==3.6.1
pytz==2018.9
setuptools==39.1.0
six==1.12.0

如果有人可以提供帮助，将不胜感激。我确定我昨天做了一些愚蠢的事情而忘记了。

我是个白痴，我没有选择 PyCharm 使用 Django 运行我的应用程序。

对于任何这样做的人，PyCharm 右上角的下拉菜单。
