Pyquery的安装

无论Linux还是Mac, 要安装pyquery都不是一件容易的事儿

主要是lxml的依赖较多，且需要手动安装

cat /etc/redhat-release
CentOS release 6.6 (Final)

1>>python-dev

yum install gcc libffi-devel python-devel openssl-devel

2>>libxslt, libxml

curl -o libxslt-1.1.29.zip https://git.gnome.org/browse/libxslt/snapshot/libxslt-1.1.29.zip

  curl -o libxml-1.7.3.tar.gz http://xmlsoft.org/sources/old/libxml-1.7.3.tar.gz

但是为何安装完了还是各种错误呢！

搜索StackOverflow

yum instal libxslt-devel

然后也就安装成功了

ubuntu下就简单多了

sudo apt-get install python-lxml

Pyquery使用是特别方便的
