python如何升级到指定版本_python如何升级?

如何升级到python3版本并且安装pip3准备：

Python-3.5.2.tar.xz

pip-8.1.2.tar.gz

setuptools-24.0.2.zip

接下来跟着我一起升级安装吧~~~~~~

步骤：

1、自定义编译安装python3.x版本

tar Jxf Python-3.5.2.tar.xz

cd Python-3.5.2

./configure --prefix=/usr/local/Python3

make && make install

2、安装pip3.x，安装会提示需要setuptools模块，所以需要先安装setuptools模块

tar zxf pip-8.1.2.tar.gz

tar zxf setuptools-24.0.2.zip

cd setuptools-24.0.2

ln -s /usr/local/Python/bin/python3 /usr/bin/python3

python3 setup.py install

cd ..

cd pip-8.1.2

python3 setup.py install

ln -s /usr/local/Python3/bin/pip3 /usr/bin/pip3

3、验证模块是否正常安装

python3 -m pip list

decorator (4.0.10)

ipython (4.2.1)

ipython-genutils (0.1.0)

pexpect (4.2.0)
