python docker抛出错误：AttributeError:模块“six”没有属性“PY34”

Question

我正在写一个脚本，它将构建docker映像，然后将映像推送到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的第一行，我得到了以下错误。这意味着，它还没有建立形象，以推动进入ECR。你知道吗

import docker-->；抛出下面的错误

Traceback (most recent call last):

AttributeError: module 'six' has no attribute 'PY34'

已经安装了6个

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

它似乎是针对python34的，那么对于python38，我如何解决这个问题呢？你知道吗

很可能是six版本不够高，c.f.https://github.com/docker/docker-py/issues/2294

首先检查六个版本：

import six
print(six.__version__)

如果six version不是>；=1.0.0，则在命令行上升级six

python -m pip install -U six

使用最新的pip，您应该看到：

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