When working on a Python project, you may encounter an error message that says “ImportError: No module named mysql.connector.”
Therefore, this article will explore this error and provide solutions to resolve it.
What is Importerror: no module named mysql.connector?
The ImportError: No module named mysql.connector is an error message that indicates that the mysql.connector module is not installed on your system.
You can install it using the pip command. If you are using Python 3, you can run pip3 install mysql-connector-python.
If you are using Python 2.X, you can use pip install mysql-connector-python
Common causes of the ImportError
The no module named mysql.connector’ import error can occur due to various reasons.
Some common causes include:
- Missing module installation: The ‘mysql.connector’ module might not be installed on your system, requiring you to install it manually.
- Incorrect module import statement: The import statement for the module might be incorrect, resulting in the ImportError.
- Incompatible module version: The installed version of the ‘mysql.connector’ module might not be compatible with your Python environment.
- Conflicting module versions: Other installed modules or packages might conflict with the ‘mysql.connector’ module, leading to import issues.
How to fix Importerror: no module named mysql.connector
To fix the ImportError: No module named mysql.connector error, you need to install the mysql-connector-python module.
In installing the module run the following command in the terminal.
pip install mysql-connector-pythonFor Python 3, use the command below.
pip3 install mysql-connector-pythonYou can also install the MySQL driver mysql-connector-python-rf to import mysql.connector in Python.
pip install mysql-connector-python-rfAfter installing the module, run the Python program again, and the ImportError must be solved now.

Best practices for module management
To avoid import errors and other module-related issues, it is important to follow best practices for module management.
Some recommendations include:
- Regularly update modules to the latest versions to leverage bug fixes and new features.
- Use virtual environments to isolate project-specific modules and prevent conflicts.
- Document module dependencies in a ‘requirements.txt’ file to ensure consistent installations across different environments.
- Be mindful of version compatibility between modules and Python versions.

Frequently Asked Questions
What is Python ImportError and what causes it?
ImportError is raised when an import fails for any reason. The most specific subtype is ModuleNotFoundError (no such module). Plain ImportError typically means the module exists but a name inside it can’t be imported, e.g. ‘cannot import name X from Y’ (X was renamed, removed, or moved between versions of Y). Common with library version mismatches.
How do I fix ‘cannot import name X from Y’?
Three steps: (1) Check the library version: pip show Y. (2) Check the changelog of Y, X may have been renamed or removed in a recent release. (3) Either pin to an older Y version (pip install Y==1.x.y) or update your code to the new import path. Common 2025-2026 examples: Werkzeug url_decode removed, Pillow ANTIALIAS renamed to LANCZOS.
Why does the import work in REPL but fail in script?
Two reasons. (1) Different Python interpreter: REPL uses one Python, your script uses another. Run python –version both times. (2) Different working directory: REPL is started where you have access to local modules, script is run from a different cwd. Add the project path to sys.path or use python -m to run as a module.
How do I avoid circular import errors?
Circular imports happen when module A imports B and B imports A at the top level. Three fixes: (1) Move one import inside the function that uses it (lazy import). (2) Restructure code so A and B both import from a third module C. (3) Use TYPE_CHECKING for type-hint-only imports: if TYPE_CHECKING: from a import X.
Where can I find more ImportError fixes?
