`cPickle.UnpicklingError` after 4.8.5 update #13

Closed pberkes closed 9 years ago

Here's what happened: 1) I ran enpkg and it asked to update. I did.

↳ enpkg -s engeo

I don't know why, but the enpkg you are using is not the updated one (and is instead from canopy application....).

Can you paste the content of /Users/pberkes/Library/Enthought/Canopy_64bit/User/bin/enpkg ?

hm, from your user env python, can you do the following:

$ python
import sys
print(sys.path)
import enstaller
print(enstaller.__file__)

cournape commented 9 years ago

So that's the problem. For some reasons, you have the canopy app ('/Applications/Canopy.app/appdata/canopy-1.5.1.2730.macosx-x86_64/Canopy.app/Contents/lib/python2.7`) in your sys.path before user environment.

This is an issue with your environment. There are also a lots of eggs/develop entries in your sys.path, I advise you to clean those, as it increases the likelihood of such issues.

pberkes commented 9 years ago

ok... but who is adding that?

dpinte commented 9 years ago

@pberkes Can you ping Robin about that? It would be good to understand how we can have the appdata path before the user path.

cournape commented 9 years ago

For the .egg entries, I would look into setuptools (e.g. the easy_install.pth files in your PYTHONPATH).

For the directories entries, look into your PYTHONPATH.
