Linux安裝python2.7.9

官網地址： https://www.python.org/downloads/

一、Linux下安裝(其餘系統請自行前往官網安裝)

--- 安裝依賴包
# cd /usr/local
# yum install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gcc make -y
# wget https://www.python.org/ftp/python/2.7.9/Python-2.7.9.tgz
# tar -xzvf Python-2.7.9.tgz
# cd Python-2.7.9
# ./configure --prefix=/usr/local/Python2.7.9 --enable-shared -enable-unicode=ucs4
# make
# make install
# python -V

二、python解釋器指向python2.7.9

# which python
# cd /usr/bin
# rm python
# ln -s /usr/local/Python2.7.9/bin/python python
# python -V  --執行報錯

三、解決python -V執行報錯

# cd /etc/ld.so.conf.d/
# echo "/usr/local/Python2.7.9/lib" > python2.7.conf
# ldconfig
# python -V

四、因爲yum使用了原來python2.6的一些腳本，須要將yum從新導向原來的python2.6解釋器才能夠使用

# which yum
# vi /usr/bin/yum
----修改第一行路徑爲： #!/usr/bin/python2.6
