Linux之python版本升级

四、python3升级步骤

1、下载安装包

wget https://www.python.org/ftp/python/3.8.8/Python-3.8.8.tgz

2、解压软件包

tar -zxvf Python-3.8.8.tgz

3、预编译

注意在编译结束后会有提示"If you want a release build with all stable optimizations active (PGO, etc),please run ./configure –enable-optimizations"，加上–enable-optimizations预编译的话后续编译会报错“Could not import runpy module ”，原因是gcc版本太低，enable-optimizations参数要求gcc版本8.1.0以上。

cd Python-3.8.8

./configure

4、编译

make

if test `uname -s` = Darwin; then

cp python-config.py python-config;

fi

5、编译安装

make install

Collecting setuptools

Collecting pip
