Centos7.7编译安装Python3.6.2

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
