python - 如何配置 uwsgi 以使用特定版本的 python？

Question

我使用 Debian 9 uwsgi 和 nginx 作为多个 Django 站点的服务器。默认情况下，Debian 有 python 3.5。 uwsgi 全局安装

sudo -H pip3 install uwsgi

我决定将网站转移到 python 3.7。为此，我将源文件中的新版本 python 3.7 安装到 /usr/local/bin/python3.7 文件夹中。

我还重新创建了一个虚拟环境(与之前的名称相同)

mkvirtualenv -p /usr/local/bin/python3.7 protrack

但是现在我遇到了一个错误，uwsgi仍然使用python 3.5。

如何重新配置​​ uwsgi 以使用 python 3.7？

/etc/uwsgi/sites/protrack.ini

[uwsgi]
project = protrack
uid = gk
base = /home/%(uid)

chdir = %(base)/%(project)
home = %(base)/Env/protrack
module = protrack.wsgi:application

master = true
processes = 5

# Finish off the configuration with the following lines
socket = /run/uwsgi/protrack.sock
chown-socket = %(uid):www-data
chmod-socket = 660
vacuum = true

您可以将 uwsgi 安装到您的 virtualenv 目录(而不是全局目录)并配置它以在 nginx 中使用。这将确保 uwsgi 和您的 python 版本相同。
