lxml基本上没什么

Question

lxmlPython 的软件包似乎在我的系统上完全破碎了.我不确定这个问题,因为似乎所有文件都已到位.我怀疑是问题所在__init__.py,但我没有足够的练习系统来做出准确的诊断或解决问题.

以下是一些我认为有助于诊断问题的代码:

Python 2.6.4 (r264:75706, Dec  7 2009, 18:45:15) 
[GCC 4.4.1] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import lxml
>>> dir(lxml)
['__builtins__', '__doc__', '__file__', '__name__', '__package__', '__path__']
>>> print lxml.__path__
['/usr/lib/python2.6/dist-packages/lxml']
>>> c = open("/usr/lib/python2.6/dist-packages/lxml/__init__.py", "r")
>>> for line in c:
...     print line
... 
# this is a package



>>> c.close()
>>> import os
>>> os.system("ls /usr/lib/python2.6/dist-packages/lxml/")
builder.py      ElementInclude.py   __init__.py    sax.pyc
builder.pyc     ElementInclude.pyc  __init__.pyc       usedoctest.py
cssselect.py        _elementpath.py objectify.so       usedoctest.pyc
cssselect.pyc       _elementpath.pyc    pyclasslookup.py
doctestcompare.py   etree.so        pyclasslookup.pyc
doctestcompare.pyc  html        sax.py
0
>>> 

就像我说的,我的怀疑是__init__.py包含问题,但我不是百分百肯定.

另外,我使用的是Linux Mint 8 - 相当于Ubuntu 9.10.

提前致谢.

不,你只是做错了!试试,例如,from lxml import etree你应该能够etree完全使用. import lxml- 导入包!-并没有给你任何程序包的隐式接入模块 - !)
