我有同样的问题:

>>> import six
>>> import xhtml2pdf.pisa
Traceback (most recent call last):

from six import with_metaclass, viewkeys, PY3
ImportError: cannot import name viewkeys
>>> exit()
我跑以下步骤:
sudo -H pip uninstall six
sudo -H pip install six==1.9.0
- 测试:错误仍然存在
sudo -H pip uninstall six==1.9.0
sudo -H pip install six==1.10.0
测试:

>>> from six import viewkeys
>>> import xhtml.pisa
Traceback (most recent call last):

ImportError: No module named xhtml.pisa
>>> import xhtml2pdf.pisa
Traceback (most recent call last):

import xhtml2pdf.parser
File "xhtml2pdf/parser.py", line 17, in <module>
from html5lib import treebuilders, inputstream
ImportError: cannot import name inputstream
>>> exit()
所以viewkeys错误没有回来。
问题进口的InputStream似乎是在xhtml2pdf了一个错误:
https://github.com/xhtml2pdf/xhtml2pdf/issues/318
对于我这个固定的问题:
sudo -H pip install html5lib==1.0b8
所以毕竟,我真的不知道,如果最后一个命令可以解决整体问题,但这种方式现在对我来说很有效:

你确定没有在你的工作目录中命名'six.py'或其他吗?你可以在你的模块中尝试一个简单的'import six',然后'print(six)',看看它是否是你期望的。 – ShadowRanger
不,没有。 – PythonEnthusiast
我在python shell中也尝试过它。我试图只导入'从六个导入视图',它返回一个错误。 – PythonEnthusiast
