运行dropbox.py时出错

Question

test@SERVER:~/source/dropbox/.dropbox-dist$ ./dropbox.py      
Traceback (most recent call last):
  File "./dropbox.py", line 39, in <module>
    import urllib
  File "/usr/lib/python2.6/urllib.py", line 30, in <module>
    from urlparse import urljoin as basejoin
  File "/usr/lib/python2.6/urlparse.py", line 84, in <module>
    from collections import namedtuple
ImportError: cannot import name namedtuple

dropbox.py has 755 perms. In system I have 2 , 2.6 versions of python. Running python2 dropbox.py or python2.6 dropbox.py spits the same error.

and here is dropbox.py file from Dropbox website

Update per comment:

test@SERVER:~/source/dropbox/.dropbox-dist$ python2.6
Python 2.6.5 (r265:79063, Apr 16 2010, 13:57:41)

Answer 1

Looks like there's another module in your Python path named collections (probably collections.py but could also be a folder named collections that has an __init__.py in it) that's preventing the Python 2.6 collections module from being imported. Could be something in the directory that's current when you invoke Python -- check there first. Otherwise try python26 -c 'import sys; print sys.path' python26 -c 'import sys; print sys.path' to see where Python's looking for modules.

Answer 2

@kindall was right. The .dropbox-dist folder contains collections.so which interferes with the dropbox.py script. Move the file to a different folder. Here is one way:

mkdir cli
mv dropbox.py cli/dropbox.py
cd cli
./dropbox.py --help

Answer 3

Can you try do to

python -c 'import collections; print collections.__file__'

And ensure that the path is /usr/lib/python2.6/collections.pyc . If not, then you have another modules in your PYTHONPATH that replace this one. If yes, then try again by doing:

python -c 'import collections; print dir(collections)'

And show us the result.

Normally, namedtuple have been introduced to 2.6 so...
