我正在导入一个模块，该模块又导入了six，但出现了这个奇怪的错误。
Traceback (most recent call last):

from six import with_metaclass, viewkeys, PY3
ImportError: cannot import name viewkeys
我看一下six.py，它里面有
viewkeys。已安装最新的
six==1.10.0。 最佳答案
我有同样的问题:

我执行以下步骤:
sudo -H pip uninstall six sudo -H pip install six==1.9.0 sudo -H pip uninstall six==1.9.0 sudo -H pip install six==1.10.0 测试:

from html5lib import treebuilders, inputstream
ImportError: cannot import name inputstream
>>> exit()
因此，viewkeys-error并没有回来。
导入inputstream的问题似乎是xhtml2pdf中的错误:

对我来说，这解决了这个问题:
sudo -H pip install html5lib==1.0b8因此，毕竟，我真的不知道最后一个命令是否可以整体解决问题，但是这种方式现在对我有用:
