如何升级到python3版本并且安装pip3及ipython3

Posted 2023-03-16

参考技术A 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)
pickleshare (0.7.2)
pip (8.1.2)
ptyprocess (0.5.1)
setuptools (24.0.2)
simplegeneric (0.8.1)
traitlets (4.2.2)
4、安装ipython
