问题：

Docker：执行"RUN pip install--no-cache /wheels/*"命令时出错

仇高韵
2023-03-14

我试图通过上的教程将Django与Postgres、Gunicorn和Nginx对接

https://testdriven.io/blog/dockerizing-django-with-postgres-gunicorn-and-nginx/

docker在第7步时，我遇到了一个错误，即，

步骤7/23：运行pip-wheel-no-cache-dir-no-deps-wheel-dir/usr/src/app/wheels-r-requirements。txt文件

我能够更新Dockerfile。prod克服了这个错误，但我在步骤21中遇到了另一个错误

步骤21/26：运行pip安装--无缓存/轮子/*

这是我更新的Dockerfile。戳

多亏了@DawidGacek的建议，我为这两个容器都添加了依赖项，现在它工作得很好。这是最后一个工作Dockerfile。prod[注意：我刚刚注释了flake8 lint checker，如果您需要相同的，只需取消注释即可]
