Posted 2020-12-25 lingfeng-sun

ubuntu16 默认python3.5，需要安装3.6版本


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

sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.5 1 

sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.6 2

sudo update-alternatives --config python3

sudo apt-get install python3-pip

sudo pip3 install --upgrade pip

如果报错：ModuleNotFoundError: No module named ‘gdbm‘

sudo apt-get install python3.6-gdbm

如果报错  _internal ，可以选择强制安装，命令如下
sudo curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
sudo python3 get-pip.py --force-reinstall
