由于我是 python 新手，所以我无法收到此错误。 任何帮助都非常感谢

谢谢

Answer 1

这个错误基本上意味着你没有正确安装python。某些应用程序需要 python3.7 而您没有使用apk add python3 指定版本。因此，可能已安装最新版本 (3.8)。

这个article 处理如何为bitbucket 管道中的代理选择给定的python 版本。基本上可以归结为：

image: python:3.7
pipelines:
  default:
    - step:
        script:
          - python --version

您是否有理由必须使用 Alpine？否则我会选择上面的务实形象。
