Posted 2021-01-12 david2018098

按照本文升级到3.6,但pip无法运行了，问题没有解决

1.添加python3.6安装包,并且安装

sudo apt-get install software-properties-common

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

2.修改系统默认python版本为3.6

cd /user/bin
rm python
ln -s python3.6m python

 

重新安装pip成功

重新安装pip，命令格式：

python get-pip.py

另一问题的出现解决方案

更换python版本后出现 No module named "apt_pkg"

$ sudo apt-get remove --purge python-apt$ sudo apt-get install python-apt -f$ sudo find / -name "apt_pkg.cpython-35m-x86_64-linux-gnu.so"$ cd /usr/lib/python3/dist-packages/$ sudo cp apt_pkg.cpython-35m-x86_64-linux-gnu.so apt_pkg.cpython-36m-x86_64-linux-gnu.so
