linux/centos6.5下编译安装python2.7和python3.5.2

python


解压python源码包

tar -xf Python-2.7.6.tar.xz

进入软件包目录

cd Python-2.7.6

添加配置项

./configure --prefix=/usr/local/python27

编译

make

报错

Python build finished, but the necessary bits to build these modules were not found:

_bsddb             _sqlite3           _ssl            

_tkinter           bsddb185           bz2             

dbm                dl                 gdbm            

imageop            sunaudiodev                        

To find the necessary bits, look in setup.py in detect_modules() for the module's name.


centos安装盘中有相关的依赖包安装即可(readline)

方法:

将centos6.5的光盘挂载在/mnt/cdrom目录下

mkdir /mnt/cdrom

mount /dev/cdrom /mnt/cdrom

cd /mnt/cdrom/Packages/

提示缺少readline-devel包,安装readline-devel包的时候提示依赖ncurses-devel

 rpm -ivh ncurses-devel-5.7-3.20090208.el6.x86_64.rpm

 rpm -ivh readline-devel-6.0-4.el6.x86_64.rpm

删除相关的目录重新配置并编译

rm -rf /usr/local/python27

./configure --prefix=/usr/local/python27

make

make install

后面继续报缺少依赖包直接忽略

②安装ipython1.2.1

tar -xf ipython-1.2.1.tar.gz

cd ipython-1.2.1

使用python27对ipython进行编译

/usr/local/python27/bin/python2.7 setup.py build

编译成功执行安装

/usr/local/python27/bin/python2.7 setup.py install


如果安装成功则在/usr/local/python27/bin目录下有一个ipython文件

ls /usr/local/python27/bin/


######################

将python和ipython链接到bin目录下,方便调用(直接输入python和ipython命令即可)

ln -sv /usr/local/python27/bin/python2.7 /usr/bin/python27


ln -sv /usr/local/python27/bin/ipython /usr/bin/

centos6.5环境python3.5的安装



安装相关依赖:

yum -y install xz wget gcc make gdbm-devel openssl-devel sqlite-devel zlib-devel bzip2-devel

安装python3:

wget http://mirrors.sohu.com/python/3.5.2/Python-3.5.2.tar.xz

tar -xf Python-3.5.2.tar.xz

cd Python-3.5.2

./configure --enable-shared --enable-loadable-sqlite-extensions --with-zlib

make && make install

添加python3命令:

ln -sv /usr/local/bin/python3.5 /usr/bin/python3

vim /etc/ld.so.conf

/usr/local/lib # 新增库文件路径

include ld.so.conf.d/*.conf

# 使配置库生效

/sbin/ldconfig

版本检测

# python3 -V

Python 3.5.2


以后直接运行python3就可以通过python3.5.2版本执行命令了
