我已经设置了 pytest (3.1.0) 和 pytest-django (3.1.2) 来运行一些测试。这在 Ubuntu 17.04 和 OSX 10.12.2 上效果很好，但在我们的测试环境（Ubuntu 12.04.5）上却不行。

查看时pytest --version，在一切都按预期工作的环境中检测到该插件，但在测试服务器上未列出该插件。这会导致错误，例如ImproperlyConfigured: Requested setting CACHES, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings.工作环境的输出：

$ venv/bin/pytest --version
This is pytest version 3.1.0, imported from /home/me/code/myproject/myproject_device/venv/local/lib/python2.7/site-packages/pytest.pyc
setuptools registered plugins:
  pytest-django-3.1.2 at /home/me/code/myproject/myproject_device/venv/local/lib/python2.7/site-packages/pytest_django/plugin.py

在搜索详细信息时，我发现了一些关于抑制 pytest 插件的导入错误的 pytest 问题（fi https://github.com/pytest-dev/pytest/issues/1307），但这些是指行为的变化对于 pytest 3，此类问题会出现错误或警告。但是除了 django 本身的 ImproperlyConfigured 异常之外，我没有看到任何错误。完整输出：

ubuntu/precise64我可以毫无问题地在一个流浪的盒子里重现这个。我尝试将 python 2.7 升级到更新版本，但也没有任何区别。

那么如何追踪阻止pytest-django插件加载的错误呢？
