lxml包引入错误

在使用第三方包lxml引入etree模块时报错：

>>> from lxml import etree
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
ImportError: dynamic module does not define init function (initetree)

   由于之前安装是直接使用源码包进行安装，报错之后决定卸载掉源码安装的版本（直接删除site-packages目录下面的lxml包文件），然后重新使用easy_insall命令安装，安装过程中报错信息如下：

ERROR: /bin/sh: xslt-config: command not found

** make sure the development packages of libxml2 and libxslt are installed **

    于是分别安装libxml2 and libxslt模块：

1027  yum install libxml2
1028  yum install libxslt

   检查xslt-config命令是否安装成功：

[root@oser623 mongodb]# whereis xslt-config
xslt-config:
[root@oser623 mongodb]#

   xslt-config命令还是不存在，在网上找了找资料，提示说需要安装 libxslt-devel

1033  yum install libxslt-devel

   现在再来尝试安装 lxml模块

[root@oser623 mongodb]# whereis xslt-config
xslt-config: /usr/bin/xslt-config
[root@oser623 mongodb]# easy_install lxml
