Python - 无法导入名称视图
我正在导入一个模块,它会导入six
,但我收到了这个奇怪的错误。Python - 无法导入名称视图
Traceback (most recent call last):

from six import with_metaclass, viewkeys, PY3
ImportError: cannot import name viewkeys
我在six.py倒是一看,它有它viewkeys
。
最新安装了six==1.10.0
。
我有同样的问题:

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:

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:

>>> import xhtml2pdf.pisa
>>>
我有同样的问题,并安装html5lib == 1.0b8给我相同的导入错误:/ – Matt
对我来说,PIP w因为不工作,所以我不能重新安装六个。
我所做的是:
下载最新的 “六个一” 包从这里: https://pypi.python.org/pypi/six
cd /tmp
wget [GET LATEST SIX URL]
tar xf six-1.10.0.tar.gz
cd six-1.10.0
python3 setup.py install
现在PIP工作在Python 3,如果你需要它的Python 2只是改变“python3”代表最后一个命令中的“python2”。
这是我的MacBook Pro,OS X Yosemite,10.10上的帮助。5
1)检查了六个版本的Python是使用
import six
print six.__version__
1.4.0
2)寻找您的系统
sudo find/-name 'six*'
/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/scipy/lib/six.py
/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/scipy/lib/six.pyc
/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/six.py
/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/six.pyc
3)所有六个Python包检查六个版本逐一
vi /System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/six.py
4)当文件打开时向下滚动以识别六个版本
5)手动删除所有包年长然后1.10.0
sudo rm /System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/six.py
sudo rm /System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/six.pyc
6)安装最新6包(例如1.11.0):
sudo pip install --ignore-installed six
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
