Question

尝试使用apache运行Django时出现以下错误：

mod_wsgi (pid=3294): Target WSGI script '/www/cocurate2_dev/startup.wsgi' cannot be loaded as Python module.
mod_wsgi (pid=3294): Exception occurred processing WSGI script '/www/cocurate2_dev/startup.wsgi'.

ImportError: cannot import name signals

使用manage.py runserver时，一切正常。我已经将wsgi文件更新为与django 1.10中的默认文件相同。我已经检查过django里面的signals.py，我也清理过.pyc文件。

Answer 1

事实证明，由于各种原因，django安装中实际上缺少一个文件，它只是不是signal.py而是导入的东西。您可以通过使用-v或-vv开关运行python来调试输出详细信息来调试此类问题。我能够看到它试图从signals.py导入另一个文件。

Answer 2

当我的Django 1.10安装被第三方降级到Django 1.6时，出现了此错误。删除它并重新安装正确版本的Django后，一切都像冠军一样工作。

ImportError：在Django 1.10中导入wsgi文件时无法导入名称信号
