I get an error in python3 when importing mechanize
提问by crzyonez777
I get an error in python3 when importing mechanize.
导入 mechanize 时，在 python3 中出现错误。
I've just installed mechanize into my virtualenv where python3 is installed.
我刚刚将机械化安装到安装了 python3 的 virtualenv 中。
$ 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.
但是，当我尝试在我的 python 代码中导入 mechanize 时，我收到了这个错误。
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 think you may have installed the Python 2 version of mechanize, and the new Python 3 import semantics are breaking the old Python 2 code. A quick search, and it seems like Python 3 support for mechanize is still a bit weak. However, I did find a Python 3 branch.
我想你可能已经安装了 Python 2 版本的 mechanize，新的 Python 3 导入语义正在打破旧的 Python 2 代码。快速搜索，似乎 Python 3 对机械化的支持仍然有点弱。但是，我确实找到了Python 3 分支。
You could try manually installing from the source code I linked to. Once you've downloaded the source, change your directory so that you're in the mechanize directory. Then enter $python3 setup.py installin the terminal.
您可以尝试从我链接到的源代码手动安装。下载源代码后，更改您的目录，使您位于 mechanize 目录中。然后$python3 setup.py install在终端输入。

Alas, mechanize doesn't support Python 3. http://wwwsearch.sourceforge.net/mechanize/faq.html
唉，机械化不支持 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.
Python 2.4、2.5、2.6 或 2.7。尚不支持 Python 3。

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

The module MechanicalSoup merged Mechanical and BeautifulSoup in the same Library and can be used since Python 2.6 through 3.4.
MechanicalSoup 模块将 Mechanical 和 BeautifulSoup 合并在同一个库中，并且可以从 Python 2.6 到 3.4 使用。
in command prompt install MechanicalSoup:
在命令提示符下安装 MechanicalSoup：
pip install MechanicalSoup
Then import in python,
然后在python中导入，
import mechanicalsoup # Don't forget to import the new module
