Centos7.7编译安装Python3.6.2
Python-3.6.4.tgz
提取码：aw09
首先安装Python依赖包
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 libffi-devel
1、新建文件夹下载Python3.6.2安装包
wget https://www.python.org/ftp/python/3.6.2/Python-3.6.2rc1.tgz
2、解压缩
tar -zxvf Python-3.6.2rc1.tgz
3、配置、检查依赖
cd Python-3.6.2rc1
./configure --prefix=/usr/local/python36
#--prefix后跟着的就是安装路径`
4、编译&安装
make && make install
5、错误分析
zipimport.ZipImportError: can't decompress data; zlib not available
make: *** [install] Error 1
根据错误信息分析，就是缺少了zlib的解压缩类库，安装即可
yum -y install zlib*
安装之后再执行make && make install编译，出现Successfully即为安装成功
6、创建软链接
使用ln -s创建软链接将python3、pip加入启动命令
①进入Python3安装目录
cd /usr/local/python36/bin
②创建软链接python3和pip3命令
# 使用绝对路径
ln -s /usr/local/python36/bin/python3.6 /usr/bin/python3
ln -s /usr/local/python36/bin/pip3.6 /usr/bin/pip3
7、测试安装是否成功
任意目录下输入
python3 --version
pip3 --version
安装成功
