任何人都可以，请向我解释这里发生了什么。当我尝试登录雅虎邮箱时，Python 似乎拒绝工作（使用斜纹布）：

更新 1：
（此更新是我对 Robus 的回答）
你好，罗布斯！！！
首先，我认为你写的时候是一个错字：
这是我所做的：去了 C:\Python26\Lib\site-packages\twill-0.9-py2.6.egg\twill\other_packages\
我认为您的意思是这条路径：“ C:\Python26\Lib\site-packages\twill\other_packages ”。否则，我看不到任何名为“ twill-0.9-py2.6.egg ”的文件夹/目录 - 只有一个具有此名称的文件（我认为是在安装 mechanize 期间下载的文件。）请告诉我我的假设是否错误 - 我可能在这里看不到非常明显的东西，因为我只是一个新手。
因此，按照您的指示，我这样做了：
我在我的电脑上找到了“ C:\Python25\Lib\site-packages\twill\other_packages_mechanize_dist ”（如您所见，我没有安装 python26，而是安装了 python 25 - 这也可能是一个问题）
将其名称更改为“ _mechanize_dist_backup ”（完整路径现在为“ C:\Python25\Lib\site-packages\twill\other_packages_mechanize_dist_backup ”）
将我下载并解压缩的“ mechanize-0.2.2 ”复制到“ C:\Python25\Lib\site-packages\twill\other_packages ”（完整路径为“ C:\Python25\Lib\site-packages\twill\other_packages\机械化-0.2.2 ")
将其名称更改为“ _mechanize_dist ”（完整路径为“ C:\Python25\Lib\site-packages\twill\other_packages_mechanize_dist ”）
从“ _mechanize_dist_backup ”复制“ ClientForm ”文件并将其粘贴到“ _mechanize_dist ”中（实际上，我在那里找到了两个名为“ ClientForm ”的文件：一个是python文件，另一个是编译的python文件 - 我复制并粘贴了两个他们）。
完成之后，我尝试运行所有这些命令，但一开始就卡住了——我现在什至无法导入斜纹：
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>

File "C:\Python25\Lib\site-packages\twill\commands.py", line 7, in <module>
import _mechanize_dist as mechanize
ImportError: No module named _mechanize_dist
系统似乎无法识别新创建的“ _mechanize_dist ”。
可能是因为我有 Python 25 而不是 Python 26？或者，也许，还有其他原因？
