Why does Python (with twill) not want to log me in

问题:

Can anyone, please, explain to me what's going on here. It seems that Python refuses to work (with twill) when I am trying to log in to my mailbox on Yahoo:

Python 2.5.4 (r254:67916, Dec 23 2008, 15:10:54) [MSC v.1310 32 bit (Intel)] on win32
Type "copyright", "credits" or "license()" for more information.

Update 1:

(this update is my answer to Robus)

Hello, Robus!!!

First of all, I assume it was a typo when You wrote:


Here's what I did: Went to C:\Python26\Lib\site-packages\twill-0.9-py2.6.egg\twill\other_packages\


I think You meant this path: "C:\Python26\Lib\site-packages\twill\other_packages". Otherwise, I can't see any such folder/directory there named "twill-0.9-py2.6.egg" - there is only a file with this name (the one that I think was downloaded during the installation of mechanize.) Please tell me if my assumption is wrong - I may well be not seeing something very obvious here as I am just a newbie.

So, following Your instructions, I did this:

  1. I found "C:\Python25\Lib\site-packages\twill\other_packages_mechanize_dist" on my computer (as You can see, I don't have python26, but rather python 25 installed - that might also be a problem)

  2. Changed its name to "_mechanize_dist_backup" (the full path now being "C:\Python25\Lib\site-packages\twill\other_packages_mechanize_dist_backup")

  3. Copied my downloaded and unzipped "mechanize-0.2.2" into "C:\Python25\Lib\site-packages\twill\other_packages" (the full path being "C:\Python25\Lib\site-packages\twill\other_packages\mechanize-0.2.2")

  4. Changed its name to "_mechanize_dist" (the full path being "C:\Python25\Lib\site-packages\twill\other_packages_mechanize_dist")

  5. Copied "ClientForm" file from "_mechanize_dist_backup" and pasted it in "_mechanize_dist" (in fact, I found two files there named "ClientForm": one is a python file, another one is a compiled python file - I copied and pasted both of them).

Having done that, I tried running all those commands and got stuck at the very beginning - I couldn't even import twill now:


IDLE 1.2.4      
>>> import twill

Traceback (most recent call last):
  File "<pyshell#0>", line 1, in <module>
    import twill
  File "C:\Python25\Lib\site-packages\twill\__init__.py", line 52, in <module>
    from shell import TwillCommandLoop
  File "C:\Python25\Lib\site-packages\twill\shell.py", line 9, in <module>
    from twill import commands, parse, __version__
  File "C:\Python25\Lib\site-packages\twill\commands.py", line 7, in <module>
    import _mechanize_dist as mechanize
ImportError: No module named _mechanize_dist

It seems that the system doesn't recognize the newly-created "_mechanize_dist".

Could it be because I have Python 25 instead of Python 26? Or, perhaps, there is some other reason?

回答1:

The problem lies in Mechanize. You need the newest version

su
git clone git://github.com/jjlee/mechanize.git
cd mechanize
python setup.py install
