最近一個python項目需要用到libxml2dom這個包，然後就pip安裝之，之後驗證安裝是否成功：
shandow@mac:~ > python Python 2.7.5 (default, Mar 9 2014, 22:15:05) [GCC 4.2.1 Compatible Apple LLVM 5.0 (clang-500.0.68)] on darwin Type "help", "copyright", "credits" or "license" for more information. >>> import libxml2dom Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/Library/Python/2.7/site-packages/libxml2dom/__init__.py", line 24, in <module> from libxml2dom.macrolib import * File "/Library/Python/2.7/site-packages/libxml2dom/macrolib/__init__.py", line 26, in <module> from libxml2dom.macrolib.macrolib import * File "/Library/Python/2.7/site-packages/libxml2dom/macrolib/macrolib.py", line 30, in <module> from libxmlmods import libxml2mod ImportError: No module named libxmlmods
意思是缺乏libxmlmods庫，使用pip安裝之，提示找不到。。。。好吧，度娘問吧，找到一個類似libxml2dom的官方聲明似的網站：
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)
Introduction
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).
這裏第一句話就是libxml2dom依賴libxml2庫，可以通過查找python-libxml2或者libxml2-python下載，可是偶使用pip安裝都提示找不到資源。。。。好吧，再次度娘，手動下載了這個包。這裏貼出我分享出來的地址：libxml2下載（我的是mac os系統，windows系統的自行下載吧，哈哈。。。）再說下mac os下如何安裝：
1.先把下載的tar包放到自己python環境的site-packages,我的是：
/Library/Python/2.7/site-packages
2.解壓：sudo tar -xvf libxml2-2.7.8.tar
3.進入解壓後的文件夾,由於是源碼包需要編譯安裝：
cd libxml2-2.7.8
sudo ./configure
sudo make
sudo make install
好了，如果沒有報錯就ok了，測試下把：
python
import libxml2
提示沒有這個模塊，說明沒有導成功，鬱悶。。。。
重新進入文件夾 ：
cd libxml2-2.7.8
發現這個文件夾中有個python文件夾，進入：
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

shandow@mac:/Library/Python/2.7/site-packages/libxml2-2.7.8/python >
sudo python setup.py build
sudo python setup.py install
這兩句運行完後，重新進入site-packages文件夾，發現多了libxml2的egg-info文件：
再次測試：

>>> import libxml2
>>> import libxml2dom

libxml2安裝成功了，libxml2dom也不會報錯了，大功告成。。。。。網上百度，google都沒有這個問題的解決辦法，作者這裏原創一個，哈哈。。。
