Python - cannot import names

I am importing a module that imports six imports, but I am getting this strange error.

 Traceback (most recent call last): File "/Users/praful/Desktop/got/modules/categories/tests.py", line 13, in <module> import microdata File "build/bdist.macosx-10.10-intel/egg/microdata.py", line 4, in <module> File "/Library/Python/2.7/site-packages/html5lib/__init__.py", line 16, in <module> from .html5parser import HTMLParser, parse, parseFragment File "/Library/Python/2.7/site-packages/html5lib/html5parser.py", line 2, in <module> from six import with_metaclass, viewkeys, PY3 ImportError: cannot import name viewkeys

I would look at six.py , it has viewkeys in it.

Installed last six==1.10.0 .

I had the same problem:

 > python Python 2.7.10 (default, Oct 23 2015, 19:19:21) [GCC 4.2.1 Compatible Apple LLVM 7.0.0 (clang-700.0.59.5)] on darwin Type "help", "copyright", "credits" or "license" for more information. >>> import six >>> import xhtml2pdf.pisa Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/Library/Python/2.7/site-packages/xhtml2pdf/pisa.py", line 3, in <module> from xhtml2pdf.document import pisaDocument File "/Library/Python/2.7/site-packages/xhtml2pdf/document.py", line 2, in <module> from xhtml2pdf.context import pisaContext File "/Library/Python/2.7/site-packages/xhtml2pdf/context.py", line 23, in <module> import xhtml2pdf.parser File "/Library/Python/2.7/site-packages/xhtml2pdf/parser.py", line 17, in <module> from html5lib import treebuilders, inputstream File "/Library/Python/2.7/site-packages/html5lib/__init__.py", line 16, in <module> from .html5parser import HTMLParser, parse, parseFragment File "/Library/Python/2.7/site-packages/html5lib/html5parser.py", line 2, in <module> from six import with_metaclass, viewkeys, PY3 ImportError: cannot import name viewkeys >>> exit()

I have completed the following steps:

  • sudo -H pip uninstall six
  • sudo -H pip install six==1.9.0
  • Test: error persists.
  • sudo -H pip uninstall six==1.9.0
  • sudo -H pip install six==1.10.0

Test:

 > python Python 2.7.10 (default, Oct 23 2015, 19:19:21) [GCC 4.2.1 Compatible Apple LLVM 7.0.0 (clang-700.0.59.5)] on darwin Type "help", "copyright", "credits" or "license" for more information. >>> from six import viewkeys >>> import xhtml.pisa Traceback (most recent call last): File "<stdin>", line 1, in <module> ImportError: No module named xhtml.pisa >>> import xhtml2pdf.pisa Traceback (most recent call last): File "<stdin>", line 1, in <module> File "xhtml2pdf/pisa.py", line 3, in <module> from xhtml2pdf.document import pisaDocument File "xhtml2pdf/document.py", line 2, in <module> from xhtml2pdf.context import pisaContext File "xhtml2pdf/context.py", line 23, in <module> import xhtml2pdf.parser File "xhtml2pdf/parser.py", line 17, in <module> from html5lib import treebuilders, inputstream ImportError: cannot import name inputstream >>> exit()

So the viewkeys error did not return.

The input import problem seems to be an error in xhtml2pdf:
https://github.com/xhtml2pdf/xhtml2pdf/issues/318

For me, this fixed the problem:
sudo -H pip install html5lib==1.0b8

So, I do not know if the last command really fixed the problem as a whole, but now it works for me now:

This is what helped me on MacBook Pro, OS X Yosemite 10.10.5

1) Check which of the six versions your Python uses

 import six print six.__version__ 1.4.0

2) Find all six Python packages on your system

 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) Check six versions one at a time

 vi /System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/six.py

4) When the file opens, scroll down to identify the six versions

5) Manually remove all packages older than 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) Install the last six packages (e.g. 1.11.0):

 sudo pip install --ignore-installed six

For me, PIP did not work, so I cannot reinstall six.

What I've done:

Download the latest “six” package from here: 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

Now PIP works in Python 3, if you need it for Python 2, just change "python3" to "python2" in the last command.
