【问题描述】：
我正在使用django、nginx 和gunicorn 运行一个项目，它在本地计算机上运行良好。当我将项目移动到服务器并安装所有内容时，我使用python3 manage.py runserver 测试了项目，它工作正常。
但是当我尝试使用gunicorn 运行它时，我遇到了这个错误
ImportError: 没有名为 django_jalali 的模块
完整的gunicorn 命令：
gunicorn iteachyou.wsgi:application --bind 127.0.0.1:8003
我已经安装了这个包，它没有实际问题。
这个问题here 有一个几乎类似的问题，但它与wsgi 相关。我猜我的有点奇怪。
这是完整的回溯：

如果需要，这是我安装 pip3 install django-jalali 时发生的情况：

更新
我确信gunicorn 正在使用python2.7。
我尝试卸载然后重新安装。但它仍在使用python2.7。
如何让它改用python3？
更新 2
我尝试卸载 django 2，然后卸载 gunicorn 并重新安装所有内容。但是gunicorn还是用python2.7。
【问题讨论】：
-
确保您的
django_jalali设置中有INSTALLED_APPS -
@Satendra 我愿意。该项目在本地机器上或在服务器上使用
manage.py runserver运行良好。我发现了问题（更新 1）。但我无法修复它 -
为了让您的项目使用 python3 运行，请使用 python3 创建 virtualenv。
virtualenv -p python3 envname -
希望SO answer 对您有所帮助
-
@Satendra 谢谢。但是已经尝试了那里的所有解决方案。没有帮助。
