关于lxml.cssselect

如下所示:

import lxml.cssselect

---------------------------------------------------------------------------
ImportError                               Traceback (most recent call last)
<ipython-input-4-6858f2f5b120> in <module>()
----> 1 import lxml.cssselect


/usr/lib/python2.7/dist-packages/lxml/cssselect.py in <module>()
     14 except ImportError:
     15     raise ImportError(
---> 16         'cssselect does not seem to be installed. '
     17         'See http://packages.python.org/cssselect/')
     18 

ImportError: cssselect does not seem to be installed. See http://packages.python.org/cssselect/

原因:没有安装cssslect包，lxml.cssselect的代码中使用cssselect包

解决方法：sudo pip install cssselect
