python - 带有 urls.py 文件的线程 django-main-thread 中的异常

Question

我遇到了 Django urls.py 文件的问题。当我写python manage.py runserver这个错误弹出：

Exception in thread django-main-thread:
Traceback (most recent call last):

它只发生在新项目（从 GitHub 下载的项目工作得很好）并且只有在 urls.py 中添加路径之后才会发生。我在这个站点上查看了许多 django-main-threads，但没有一个对我有帮助。

网址.py

from test_project.test_app.views import main_view

urlpatterns = [
    path('admin/', admin.site.urls),
    path('', main_view())
]

如果我写from test_app.views import main_view它会显示错误“未解析的引用'test_app'”。

settings.py INSTALLED_APPS

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'test_app'
]

视图.py

def main_view(request):
    return HttpResponse("Why won't you work?")
