python - 如何使用 Uwsgi？我的 python 主路径在哪里？

Question

我正在尝试使用 ec2 部署我的 django 应用程序。我遵循一些指示。
但是当我尝试连接 Uwsgi 和我的 django 应用程序时，出现了问题

/home/ubuntu/.local/share/virtualenvs/unifolio-back-_HCbnSkq/bin/python

问题是什么？我猜python路径有问题......但我无法解决这个问题。

Ubuntu 的使用 uwsgi的基于插件的架构。为了成功运行 Python 3 应用程序，您需要 uwsgi-plugin-python3插入。首先，使用 apt 安装它:

$ sudo apt install uwsgi-plugin-python3

然后，更改您的 uwsgi命令如下:

uwsgi --http :8080 --virtualenv /home/ubuntu/.local/share/virtualenvs/unifolio-back-_HCbnSkq \
      --chdir /srv/unifolio-back/ -w mysite.wsgi --plugins python3
