使用 docker 构建 django cms 应用时,出现了以下的错误信息

$ git clone git@github.com:django-cms/django-cms-quickstart.git

$ cd django-cms-quickstart

$ docker compose build web

.....

关键错误信息,是 pip install 时报错: connection broken by ‘SSLError(SSLEOFError(8, ‘EOF occurred in violation of protocol (_ssl.c:1129)’))’

这样的错误信息,如果是在操作系统使用 pip install 时发生,我们通过配置修改 pip即可解决

> pip config set global.index-url https://mirrors.aliyun.com/pypi/simple/

对于上面 docker 编译出现问题我们通过直接修改 Dockerfile  中的 pip install 指令来进行换源

RUN pip install -r requirements.txt  -i https://mirrors.aliyun.com/pypi/simple/
