django - gunicorn ImportError：没有名为 django_jalali 的模块

问题描述

我正在使用 运行一个项目django，nginx并且gunicorn在本地机器上运行良好。当我将项目移动到服务器并安装所有东西时，我使用它测试了项目python3 manage.py runserver，它工作正常。

但是当我尝试使用它运行它时gunicorn，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。

这里有一个与这个问题几乎相似的问题，但它与wsgi. 我猜我的有点奇怪。

这是完整的追溯：

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

更新

我已经确定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.

我怎样才能让它使用python3呢？

更新 2

我尝试卸载 django 2，然后卸载 gunicorn 并从新安装所有内容。但是gunicorn仍然使用python2.7。

标签： djangopython-3.xgunicorn

解决方案

最后我通过gunicorn 从源安装修复它。

pip3 install git+https://github.com/benoitc/gunicorn.git

现在gunicorn正在使用python3
