在Linux CentOS 6.6上安装Python 2.7.9
http://www.cnblogs.com/dudu/p/4294238.html
CentOS 6.6自带的是Python 2.6.6,而编译llvm需要Python 2.7以上。

checking for python… /usr/bin/python
checking for python >= 2.7… not found
configure: error: found python 2.6.6 (/usr/bin/python); required >= 2.7
yum中最新的也是Python 2.6.6,只能下载Python 2.7.9的源代码自己编译安装。

操作步骤如下:

1)安装devtoolset

yum groupinstall “Development tools”
2)安装编译Python需要的包包

yum install zlib-devel
yum install bzip2-devel
yum install openssl-devel
yum install ncurses-devel
yum install sqlite-devel
3)下载并解压Python 2.7.9的源代码

cd /opt
wget –no-check-certificate https://www.python.org/ftp/python/2.7.9/Python-2.7.9.tar.xz
tar xf Python-2.7.9.tar.xz
cd Python-2.7.9
4)编译与安装Python 2.7.9

./configure –prefix=/usr/local
make && make altinstall
5)将python命令指向Python 2.7.9

ln -s /usr/local/bin/python2.7 /usr/local/bin/python
6)检查Python版本

sh
sh-4.1# python -V
Python 2.7.9
