如何在 docker 上从 ascii postgresql 数据库切换到 utf8？

Question

我的 docker bash 出现问题，我正在尝试使用 docker-compose exec web python manage.py createsuperuser 在 django 上创建超级用户，但下面出现此错误。

Traceback (most recent call last):
  File "docker-compose", line 3, in <module>
  File "compose\cli\main.py", line 68, in main
  File "compose\cli\main.py", line 118, in perform_command
  File "compose\cli\main.py", line 431, in exec_command
  File "compose\cli\main.py", line 1236, in call_docker
  File "distutils\spawn.py", line 220, in find_executable
  File "ntpath.py", line 85, in join
UnicodeDecodeError: 'ascii' codec can't decode byte 0xe9 in position 8: ordinal not in range(128)
Failed to execute script docker-compose

我认为这是因为我的数据库 Postgresql 是用 'ascii' 而不是 utf-8 编码的，将我的 psql 数据库编码为utf-8 的命令是什么？

  db:

    container_name: PSQL

您的 docker-compose.yml 中有一个波浪号（“é”）

编辑。可能您在所涉及的路径中有重音，并且您可能在主机中遇到了一些 python 错误。您可以尝试在主机中更新python（docker-compose是用python制作的）。
