问题描述

我通过pip安装了mechanize并在导入模块时获得了错误：

I installed mechanize via pip and get an errer when I import the module:

$ python
Python 3.5.2 (default, Jun 28 2016, 08:46:01)
[GCC 6.1.1 20160602] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import mechanize
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python3.5/site-packages/mechanize/__init__.py", line 119, in <module>
    from _version import __version__
ImportError: No module named '_version'

site-packages目录中存在 -version.py 文件：

The file -version.py is present in the site-packages directory:

$ ls /usr/lib/python3.5/site-packages/mechanize
_auth.py               __init__.py           _response.py
_beautifulsoup.py      _lwpcookiejar.py      _rfc3986.py
_clientcookie.py       _markupbase.py        _sgmllib_copy.py

_http.py               _request.py           _version.py

我缺少什么？

推荐答案

如果你看看你会看到 mechanize 是 Python 2.x package：

If you look at setup.py you'll see mechanize is a Python 2.x package:

Programming Language :: Python
Programming Language :: Python :: 2
Programming Language :: Python :: 2.4
Programming Language :: Python :: 2.5
Programming Language :: Python :: 2.6
Programming Language :: Python :: 2.7

除此之外，您还可以在中看到mechanize / __ init __。py 所有进口都是相对的：

Apart from that, you can see in mechanize/__init__.py that all imports are relative:

from _version import __version__

而非显式：

from ._version import __version__

为 Py3 支持，它列出了一些你可以尝试的替代方案。那，或者说它： - ）。

There's an issue opened for Py3 support and it lists some alternatives you could try. That, or port it :-).
