Question

我正在将django与app引擎和数据存储区一起使用。

我想测试应用程序，因为我已经更改了我的设置而没有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？

Answer 1

您的/某处似乎有一个向前斜线import。

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

LookupError：没有安装标签为'mobile_backend /'的应用
