Djengo 尝试运行 python manage.py 测试时出错

Question

为什么我从 manange.py 文件的末尾收到此错误？我正在尝试运行 python manage.py 测试。即使 tests.py 为空，我也会收到此错误。该项目运行良好，我正在尝试添加测试。

我收到错误

很抱歉回来晚了，我安装的应用程序中确实有django_rest。 这是我的 settings.py -

Answer 1

看起来您未能正确导入rest_framework库。您是否正在尝试导入此内容？

你有没有类似的东西

INSTALLED_APPS = (
...
'rest_framework',
)

http://www.django-rest-framework.org/#installation

你介意发布你 Manage.py 吗？这可能会让它更容易:)

Answer 2

看起来您缺少django-rest-framework要求。

确保已安装它，您可以使用pip freeze命令检查已安装的依赖项。我想您可能有一个名为requirementes.txt的文件或类似的东西，请尝试使用pip install -r requirements.txt安装所有依赖项。

Answer 3

您是否在设置中添加了rest_framework？

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