CentOS 6.5上安裝Python 2.7.9

標籤：

CentOS 6.6內建的是Python 2.6.6，而編譯llvm需要Python 2.7以上。

checking for python... /usr/bin/pythonchecking for python >= 2.7... not foundconfigure: error: found python 2.6.6 (/usr/bin/python); required >= 2.7

yum中最新的也是Python 2.6.6，只能下載Python 2.7.9的原始碼自己編譯安裝。

操作步驟如下：

1）安裝devtoolset

yum groupinstall "Development tools"

2）安裝編譯Python需要的包包

yum install zlib-develyum install bzip2-develyum install openssl-develyum install ncurses-develyum install sqlite-devel

3）下載並解壓Python 2.7.9的原始碼

cd /optwget --no-check-certificate https://www.python.org/ftp/python/2.7.9/Python-2.7.9.tar.xztar xf Python-2.7.9.tar.xzcd Python-2.7.9

4）編譯與安裝Python 2.7.9

./configure --prefix=/usr/localmake

make altinstall

5）將python命令指向Python 2.7.9

ln -s /usr/local/bin/python2.7 /usr/local/bin/python

6）檢查Python版本

shsh-4.1# python -VPython 2.7.9
