I get an error in python3 when importing mechanize

Question

I get an error in python3 when importing mechanize.

I've just installed mechanize into my virtualenv where python3 is installed.

$ which python3
/Users/myname/.virtualenvs/python3/bin/python3

$ pip freeze
mechanize==0.2.5

But, when I try to import mechanize in my python code, I get this error.

import mechanize

---------------------------------------------------------------------------
ImportError                               Traceback (most recent call last)
<ipython-input-1-6b82e40e2c8e> in <module>()
----> 1 import mechanize

/Users/myname/.virtualenvs/python3/lib/python3.3/site-packages/mechanize/__init__.py in <module>()
    117 import sys
    118 
--> 119 from _version import __version__
    120 
    121 # high-level stateful browser-style interface

ImportError: No module named '_version'

Does anyone know how to fix this problem?

I'm new to python and I've been studying how to program in python these days.

Thanks for your help in advance!

update

I've installed mechanize for python3. Now, I have an another error.

ImportError: cannot import name _sgmllib_copy

I checked what I've installed in my working virtualenv. I found some warnings.

$ pip freeze
cssselect==0.9.1
httplib2==0.8
ipython==1.1.0
lxml==3.2.4
## FIXME: could not find svn URL in dependency_links for this package:

pyquery==1.2.8
Warning: cannot find svn location for mechanize==0.2.6.dev-20140305

Answer 1

Alas, mechanize doesn't support Python 3. http://wwwsearch.sourceforge.net/mechanize/faq.html

Python 2.4, 2.5, 2.6, or 2.7. Python 3 is not yet supported.

Update: I wrote my own automating library MechanicalSoup. It's Python 3 compatible https://github.com/hickford/MechanicalSoup

Answer 2

The module MechanicalSoup merged Mechanical and BeautifulSoup in the same Library and can be used since Python 2.6 through 3.4.

in command prompt install MechanicalSoup:

pip install MechanicalSoup

Then import in python,

import mechanicalsoup # Don’t forget to import the new module
