我要做一个基于alpine镜像build一个python3的Docker镜像,需要安装supervisor,但是supervisor默认是只支持python2.4以上版本但是不包括python3以上版本的,此文档是介绍python3安装supervisor
报错内容
如果直接用pip3安装supervisor会提示:Supervisor requires Python 2.4 or later but does not work on any version of Python 3. You are using version 3.6.6 (default, Aug 24 2018, 05:04:18)
