Fixes Python environments where mysql-connector-python is not installed. Use when import mysql.connector fails. Not for connection or auth errors.
TL;DR: The MySQL driver is not installed. Run python -m pip install mysql-connector-python (the maintained package; the old mysql-connector is abandoned).
ModuleNotFoundError: No module named 'mysql'
Fix it
Install the right package: python -m pip install mysql-connector-python. Expected: Successfully installed.
If the ancient mysql-connector is installed, remove it first: pip uninstall mysql-connector. Expected: gone.
Verify: python -c "import mysql.connector; print(mysql.connector.version)". Expected: a version.
Add mysql-connector-python to requirements.txt.
When this applies
import mysql.connector fails with ModuleNotFoundError.
When it doesn't
The import works but connect() fails: connection/auth problem, different skills.
You use PyMySQL or mysqlclient: those are different drivers with their own installs.
Compatibility
mysql-connector-python 8.x; Python 3.8+.
Why it happens
Two similarly named packages exist (mysql-connector abandoned, mysql-connector-python maintained). Tutorials mix them up, and fresh envs have neither.
Edge cases
Some distros ship python3-mysql.connector via apt; pip is still the safer route in venvs.
