python3 和python 2 共存
1.安装基础的系统包
(因为我是在docker下启动的Linux, p_w_picpath中很多包没有装)
yum install -y hostname wget tar passwd gcc lrzsz telnet passwd tar man vim make net-tools sudo vixie-cron crontabs gcc gcc-c++ autoconf
2.安装python的依赖包
yum install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-deve libffi libffi-devel -y
3.下载
#国外地址
wget https://www.python.org/ftp/python/3.4.3/Python-3.4.3.tgz
#国内地址
wget http://mirrors.sohu.com/python/3.4.3/Python-3.4.3.tgz
4.安装
tar -zxvf Python-3.4.3.tgz
cd Python-3.4.3
./configure --prefix=/usr/local/python3
make
make altinstall
echo /usr/local/lib >> /etc/ld.so.conf.d/local.conf
ldconfig
ln -s /usr/local/python3/bin/python3.4 /usr/bin/python3
5.安装后在
python程序的执行文件:/usr/local/bin/python3.4
python应用程序目录:/usr/local/lib/python3.4
pip的执行文件:/usr/local/bin/pip3.4
6.如果要安装其他包
