Ubuntu环境下对python版本进行升级

apt-get install software-properties-common add-apt-repository ppa:jonathonf/python-3.6 apt-get update apt-get install python3.6

 

cd /usr/bin/ rm python3 ln -s python3.6 python3

 

apt-get install python3-pip

 

如果 pip 出现 No module named apt_pkg 错误 sudo apt-get remove --purge python3-apt sudo apt-get install python3-apt 后面可能会出现pip unsupported local setting

export LC_ALL=C  

No module named 'setuptools'

sudo apt-get install python3-setuptools

 

如果提示ImportError: cannot import name 'main'

编辑 /usr/bin/pip 文件，修改代码

from pip._internal import main
