Seems like you are missing a generic Python dependency:

dns.resolver

wido@wido-laptop:~$ python
Python 2.7.17 (default, Nov  7 2019, 10:07:09) 
[GCC 7.4.0] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import dns.resolver
>>> quit()
wido@wido-laptop:~$

You need to fix that.

Getting the exact same issues. followed the install exactly - why cant it just work?

[weizhouapache]

@CobbyJ workaround

pip install dnspython

[prashant2594]

@CobbyJ , I tried with the below two commands, which worked for me.

• yum install wget

• yum localinstall -y http://repo.mysql.com/yum/mysql-connectors-community/el/7/x86_64/mysql-connector-python-8.0.18-1.el7.x86_64.rpm

And i skipped below repo file and cmds:

• vi /etc/yum.repos.d/mysql-community.repo

• rpm --import http://repo.mysql.com/RPM-GPG-KEY-mysql

• yum install mysql-connector-python
