系統環境：CentOS 7.2
CentOS7安裝Python3.4 ，讓Python2和3共存
編譯需要的一些包：
yum -y groupinstall "Development tools" yum -y install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel
下載解壓並編譯
# 國內源 https://www.python.org/ftp/python/3.4.3/Python-3.4.3.tgz
# 下載 wget https://www.python.org/ftp/python/3.4.3/Python-3.4.3.tgz # 創建目錄 mkdir /usr/local/python34 -pv # 解壓並編譯 tar -zxvf Python-3.4.3.tgz cd Python-3.4.3 ./configure --prefix=/usr/local/python34 make && make install # 創建鏈接 ln -s /usr/local/python34/bin/python3 /usr/bin/python3 ln -s /usr/local/python34/bin/pip3.4 /usr/bin/pip3
可選! 刪除編譯過后的文件和所依賴的包
yum groupremove "Development tools" --remove-leaves yum remove zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-deve
