python docker 抛出错误 : AttributeError: module 'six' has no attribute 'PY34'

Question

我正在编写一个脚本，它将构建 docker 镜像，然后将镜像推送到 ECR。我当前的 python 版本是

>python --version
Python 3.8.0

因此，出于某种原因，在本地运行 python 时的第一行，我遇到了以下错误。这意味着，它还没有构建推送到 ECR 的镜像。

导入 docker --> 抛出以下错误

已经安装了六个

Requirement already satisfied: six in c:\users\appdata\local\programs\python\python38-32\lib\site-packages (1.6.1)

它似乎适用于 python 34，所以对于 python 38，我该如何解决这个问题？

Answer 1

很可能是 6 版本不够高，参见https://github.com/docker/docker-py/issues/2294

首先查看六个版本:

import six
print(six.__version__)

如果六个版本不>=1.0.0，则在命令行上升级六个

python -m pip install -U six

使用最新的pip，您应该看到以下内容:

>>> import six
>>> six.__version__
'1.13.0'
>>> six.PY34
True
