When I build the dockerc-compose to pip install psycopg2 and has the issue.

The Dockerfile:

RUN sed -i "s@http://deb.debian.org@http://mirrors.aliyun.com@g" /etc/apt/sources.list
RUN cat /etc/apt/sources.list
RUN apt-get clean  && apt-get update

RUN apt-get install -y python3-dev \
    && apt-get install -y libevent-dev \
    && pip install --default-timeout=1000 --no-cache-dir -r requirements.txt

You are trying to build psycopg2 version 2.7.3.1: that version is not compatible with Python 3.8.

You must use psycopg2 version at least 2.8.4.
