LookupError：没有安装带有标签“mobile_backend/”的应用程序

Question

我将 django 与应用引擎和数据存储一起使用。

我想测试应用程序，因为我已经更改了我的设置，不为测试创建本地数据库。 在setting.py中：

TEST_RUNNER = 'testing.DatabaselessTestRunner'

在 testing.py 中

    """Support for testing."""

from django.test.simple import DjangoTestSuiteRunner

class DatabaselessTestRunner(DjangoTestSuiteRunner):
    """A test suite runner that does not set up and tear down a database."""

    def setup_databases(self):
        """Overrides DjangoTestSuiteRunner"""
        pass

    def teardown_databases(self, *args):
        """Overrides DjangoTestSuiteRunner"""
        pass

当我运行时：python manage.py test mobile_backend/

我有一个奇怪的错误：

raise LookupError("No installed app with label '%s'." % app_label)
LookupError: No installed app with label 'mobile_backend/'.

但在我的 setting.py 中，我已将“'mobile_backend'”添加到我的 INSTALLED_APPS

有人可以帮助我吗？

谢谢

您的 import 某处似乎有一个杂散的正斜杠 /。

确保在所有相关位置导入 mobile_backend 而不是 mobile_backend/。
