Ubuntu20.04 installation evo (detailed tutorial) [pro-test effective]

---

Python version and pip version (versions after python3.0 correspond to pip3)

First, specify the python version of your computer. My Ubuntu 20.04 is installed with python3.8 (it is recommended to install a version after python3.0)

Check the current python and pip3 version:
command:

1.  cd /usr/bin          #进到python可执行目录
2.  ll -a|grep python3    #查看python3的版本
3.  ll -a|grep pip3    #查看pip3的版本

The results are as follows:

It can be seen that currently python3 points to python3.8
to delete the soft link of python3 and pip3, the command is as follows:

sudo rm -rf /usr/bin/python3
sudo rm -rf /usr/bin/pip3

Re-establish the soft links of python3 and pip3

sudo ln -s /usr/bin/python3.8 /usr/bin/python3
sudo ln -s /usr/bin/pip /usr/bin/pip3

Pay attention to the location of your own python and pip here, mine is in /usr/bin

Verify that the soft link is successful:

python3 -V
pip3 -V

The results are as follows:

So far, the problem of Python and pip has been solved.
