我目前正在 Ubuntu 18.04 LTS 上构建一个使用 Python、Flask、Docker、Docker-compose 和 Postgres 的应用程序。以前，docker-compose 构建会成功，一切都按计划进行。但是，现在我切换到另一个 Dockerfile，并且不再使用先前 Dockerfile 的缓存版本，构建会中断并出现以下错误：

PermissionError: [Errno 13] Permission denied: '/usr/lib/python3.7/__pycache__/__future__.cpython-37.pyc.140409285875056'
dpkg: error processing package python3.7-minimal (--configure):
 installed python3.7-minimal package post-installation script subprocess returned error exit status 1
Errors were encountered while processing:
 python3.7-minimal

我尝试过以下（Stackoverflow）帖子：

• 安装 Django 时出现“PermissionError：[Errno 13] 权限被拒绝：'/usr/lib/python3.5/site-packages'”
• docker-compose ， PermissionError：[Errno 13] 权限被拒绝：'/manage.py'
• 如何一步更改文件夹及其子文件夹/文件的权限？
• pip 安装失败，并显示：OSError: [Errno 13] 目录权限被拒绝
• docker-compose up && docker-compose build：PostgreSQL 错误
• https://phoenixnap.com/kb/fix-sub-process-usr-bin-dpkg-returned-error-code-1

但可惜，无济于事。

我正在使用以下文件：

Dockerfile.prod

# pull official base image
