根据错误提示可知，导致安装出错的原因是libxml2和libxslt这两个库没有安装，而且找不到xslt-config这个可执行程序，解决方法如下：
# sudo yum install libxml2
# sudo yum install libxslt
# sudo yum install libxslt-devel
2、继续使用pip命令安装pyspider
# sudo pip install pyspider

根据错误提示可知，导致安装出错的原因是Python.h: No such file or directory，即找不到Python.h这个头文件，解决方法如下：
# sudo yum install python-devel
至此，再次执行sudo pip install pyspider就可以完成pyspider的安装。
3、启动pyspider，验证安装是否成功
# pyspider
Traceback (most recent call last):
File "/usr/bin/pyspider", line 5, in
from pkg_resources import load_entry_point
File "/usr/lib/python2.6/site-packages/pkg_resources.py", line 2655, in
working_set.require(__requires__)
File "/usr/lib/python2.6/site-packages/pkg_resources.py", line 648, in require
needed = self.resolve(parse_requirements(requirements))
File "/usr/lib/python2.6/site-packages/pkg_resources.py", line 546, in resolve
raise DistributionNotFound(req)
pkg_resources.DistributionNotFound: pyquery
根据错误提示可知，在执行pyspider时找不到pyquery，但实际上在安装pyspider时pyquery已经安装了，通过pip freeze也可以看到，导致该问题的原因不详，解决方法如下：
# sudo pip install -U setuptools
4、安装pyspider所需使用的驱动
通过单纯的pyspider命令来启动pyspider时，默认会在当前目录下创建data目录，其中存放了sqlite数据库文件，该情况下无需安装任务数据库connector。如果要以分布式集群的方式来运行pyspider的话，就需要使用mysql、mongodb或postgresql作为后台数据库，使用rabbitmq、redis、beanstalk或kombu作为消息队列。官方推荐的安装方式是采用pip install pyspider[all]命令来安装所有驱动，但该方法一方面会安装一些无用的驱动，另一方面极有可能导致安装失败。因此如果已经确定后台数据库软件和消息队列软件的话，那么选择安装需要的驱动即可。例如采用mongodb作为后台数据库，采用redis作为消息队列的话，就可以通过如下命令安装：
# sudo pip install pymongo
# sudo pip install redis
