我正在跟随digitalocean.com的教程使用nginx和gunicorn部署python django应用程序，但是gunicorn指向我的旧应用程序python路径，而不是实际路径。
我用来部署应用程序的教程链接： https://www.digitalocean.com/community/tutorials/how-to-set-up-django-with-postgres-nginx-and-gunicorn-on-ubuntu-16-04。
运行命令sudo journalctl -u gunicorn后出现错误：

我实际的申请路径为：/home/szymon/digital_ocean/myprojectenv
我尝试了此命令
PYTHONPATH=`pwd`/.. gunicorn --bind 0.0.0.0:8000 myproject.wsgi:application
但它不能解决问题。
重新启动Gunicorn甚至重新安装也无法解决问题。
我希望有人可以提供解决方案来为gunicorn更新python路径。 我正在运行linux mint 19。
