'frozenset' object is not callable

问题

When I attempt to import hashlib in any context, it throws this error:

File "<stdin>", line 1, in <module>
  File "build/bdist.macosx-10.11-intel/egg/hashlib.py", line 115, in <module>
    """
TypeError: 'frozenset' object is not callable

Any idea how I can resolve this? I'm generating this error simply by opening up Terminal, running python and then typing import hashlib.

回答1:

I had the same problem yesterday, Hashlib wasn't installed and trying to install it using pip would give that error. I fixed it by installing it using easy_install instead.

Also I had to install Scipy and Microsoft Visual C++ Compiler for Python 2.7 on Windows, they were required for Hashlib

I had this problem installing hashlib on OSX (El Capitan), after a failed pip install of hashlib and re-attemp using easy_install. After the event, I had errors just calling pip, let alone loading hashlib.

Root cause was pip adding a bad egg directory path to my sys.path and PYTHONHOME:

>>> import sys
>>> print sys.path
['', '/Library/Python/2.7/site-packages/pip-8.1.2-py2.7.egg', '/Library/Python/2.7/site-packages/hashlib-20081119-py2.7-macosx-10.11-intel.egg', '/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python27.zip', '/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7', '/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-darwin', '/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-mac', '/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-mac/lib-scriptpackages', '/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python', '/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-tk', '/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-old', '/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-dynload', '/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/PyObjC', '/Library/Python/2.7/site-packages']

To fix, you can delete the file referenced directly, in my case:

rm /Library/Python/2.7/site-packages/hashlib-20081119-py2.7-macosx-10.11-intel.egg

I tried deleting just the directory reference, but after exploring here to identify the site.py and site_packages.py file belonging to my Current python version, which defines your paths, then looked at where site_packages.py was loading its paths from, it appears that the specific reference is added directly by pip? so the only workaround I could think of was to potentially hard code a line at the end of site.py to remove the reference, which I've seen on other threads.
