>>> import libxml2dom
Traceback (most recent call last):
File "<stdin>", line 1, in <mole>
File "/Library/Python/2.7/site-packages/libxml2dom/__init__.py", line 24, in <mole>

from libxmlmods import libxml2mod
ImportError: No mole named libxmlmods
意思是缺乏libxmlmods库，使用pip安装之，提示找不到。。。。好吧，度娘问吧，找到一个类似libxml2dom的官方声明似的网站：
libxml2dom
Current release: libxml2dom 0.5 (requiring the low-level libxml2 Python bindings, typically provided by the python-libxml2 or libxml2-python packages for various GNU/Linux distributions: Ubuntu, Debian, Fedora, Red Hat, SuSE)
Introction
The libxml2dom package provides a traditional DOM wrapper around the Python bindings for libxml2. In contrast to the standard libxml2 bindings, libxml2dom provides an API reminiscent of minidom, pxdom and other Python-based and Python-related XML toolkits. Performance is fairly respectable since libxml2dom makes direct use of libxml2mod - the low-level wrapping of libxml2 for Python. Moreover, serialisation of documents is much faster than many other toolkits because libxml2dom can make direct use of libxml2 rather than employing Python-level mechanisms to visit and serialise nodes.
Copyright and Licence
libxml2dom is licensed under the LGPL version 3 (or later).
这里第一句话就是libxml2dom依赖libxml2库，可以通过查找python-libxml2或者libxml2-python下载，可是偶使用pip安装都提示找不到资源。。。。好吧，再次度娘，手动下载了这个包。这里贴出我分享出来的地址：libxml2下载（我的是mac
os系统，windows系统的自行下载吧，哈哈。。。）再说下mac os下如何安装：
1.先把下载的tar包放到自己python环境的site-packages,我的是：
/Library/Python/2.7/site-packages
2.解压：sudo tar -xvf libxml2-2.7.8.tar
3.进入解压后的文件夹,由于是源码包需要编译安装：
cd libxml2-2.7.8
sudo ./configure
sudo make
sudo make install
好了，如果没有报错就ok了，测试下把：
python
import libxml2
提示没有这个模块，说明没有导成功，郁闷。。。。
重新进入文件夹 ：
cd libxml2-2.7.8
发现这个文件夹中有个python文件夹，进入：
shandow@mac:/Library/Python/2.7/site-packages/libxml2-2.7.8 > cd python/
shandow@mac:/Library/Python/2.7/site-packages/libxml2-2.7.8/python > ll

参照网上说的python第三方包的安装方式：
sudo python setup.py build
sudo python setup.py install
这两句运行完后，重新进入site-packages文件夹，发现多了libxml2的egg-info文件：
再次测试：

>>> import libxml2
>>> import libxml2dom
>>>
libxml2安装成功了，libxml2dom也不会报错了，大功告成。。。。。网上百度，google都没有这个问题的解决办法，作者这里原创一个，哈哈。。。
