Question

无法导入libxml2和libxslt在Python 2.7和CentOS 7中。

但是系统说，这些软件包安装：

Package libxml2-2.9.1-5.el7_1.2.x86_64 already installed and latest version 
Package libxml2-devel-2.9.1-5.el7_1.2.x86_64 already installed and latest version 
Package libxslt-1.1.28-5.el7.x86_64 already installed and latest version 
Package libxslt-devel-1.1.28-5.el7.x86_64 already installed and latest version

libxml2的安装步骤

yum groupinstall "Development Tools" 

yum install python-devel.x86_64 

rpmbuild -ba /usr/src/redhat/SPECS/libxml2.spec (this might not be required.) 

##go to RPMS/x86_64/ 

rpm -Uvh libxml2-python-2.7.8-1.x86_64.rpm --nodeps

安装的libxslt一步

wget http://xmlsoft.org/sources/libxslt-1.1.28.tar.gz 

cd libxslt-1.1.28 

./configure --with-python=/usr/bin/python2.7 

make 

make install
