$PYTHONPATH在使用Gunicorn和virtualen时发生更改

Question

我正在开发一个安装在Gunicorn和nginx的Flask应用程序。为了做到这一点，我必须为python Flask程序使用一个虚拟环境，我将其放在根目录中，将其命名为test/，代码位于test.py。为了使用我的模块，我从venv外部配置了必要的PYTHONPATH和PATH环境变量。他们似乎没事。问题是：当我使用Gunicorn执行test.py时，PYTHONPATH（我用sys.path得到的路径）似乎被覆盖了，我没有任何想法来修复它。PYTHONPATH已经用以前的必要目录定义了。当我激活virtualenv时，PYTHONPATH仍然是我想要的一样。但是，当我使用gunicorn（使用相同的virtualenv）时，PYTHONPATH会被覆盖。我想知道为什么会被覆盖以及如何防止。在

upstart日志/var/log/upstart/test.log的输出，它是执行test.py的日志文件。我配置的PROJ_LAST路径不见了。在

这里是暴发户。wsgi.py是应用程序的一种入口点：

但是当我尝试读取PYTHONPATH或virtualenv激活时的路径，结果如下（我想要的结果！）公司名称：

myuser@PROJcontrol:~/test/venv/bin$ source activate
