Yum command ModuleNotFoundError on centos 8

Question

I have a CentOS 8 server, and tried to install Mysql on it with following commands:

wget http://repo.mysql.com/mysql-community-release-el7-5.noarch.rpm
sudo rpm -ivh mysql-community-release-el7-5.noarch.rpm
yum update

when I enter yum update, it returns

Traceback (most recent call last):
  File "/usr/lib64/python3.6/site-packages/libdnf/common_types.py", line 14, in         swig_import_helper
    return importlib.import_module(mname)
  File "/usr/lib64/python3.6/importlib/__init__.py", line 126, in import_module

During handling of the above exception, another exception occurred:

ModuleNotFoundError: No module named '_common_types'

My python is installed via

wget https://www.python.org/ftp/python/3.8.3/Python-3.8.3.tgz
tar -zxvf Python-3.8.3.tgz
mkdir /usr/local/python3/
cd Python-3.8.3
./configure --prefix=/usr/local/python3
make
yum install zlib* -y
make install
ln -s /usr/local/python3/bin/python3.8 /usr/bin/python
ln -s /usr/local/python3/bin/pip3 /usr/bin/pip

It seems yum command is using the /usr/lib/python3.6/, which is different from the Python version I am using. How can I fix my yum command?
