In this article, we’ll show you how to fix the Modulenotfounderror: no module named ‘sqlalchemy’ that you might encounter while running your Python script.

This error usually occurs when a required module is not installed in your system.

Aside from that, there are several reasons why this error occurs, and you will learn about them all in this article.

Continue reading to learn about the error’s causes and how to troubleshoot modulenotfounderror: no module named ‘sqlalchemy’.

What is ‘sqlalchemy’ module?

The SQLAlchemy is a well-known Python library for working with databases. It includes a set of tools for interacting with relational databases using Python code.

Additionally, SQLAlchemy can be used to create and modify database schemas, as well as execute SQL queries.

Furthermore, SQLAlchemy includes an object-relational mapper (ORM) that allows you to interact with the database using Python objects instead of writing raw SQL queries.

This enables developers to interact with databases in a more object-oriented manner, making it easier to create, read, update, and delete records.

Modulenotfounderror: no module named ‘sqlalchemy’

The error “ModuleNotFoundError: No module named’sqlalchemy’” indicates that the Python interpreter was unable to locate the “sqlalchemy” module, which is required by the code you are attempting to run.

This error can occur if the “sqlalchemy” module is not installed on your system, or if it is installed but not available in the current Python environment.

How to fix Modulenotfounderror: no module named ‘sqlalchemy’

To resolve this error, here are the following solutions you can try.

  1. Check python version

    Since we need to install sqlalchemy module, we must check their version first to have the correct version of module to install.

    Use the following command to check:

    python --version

    python version

  2. Install sqlalchemy module

    To install the sqlalchemy module, open your terminal and do the following command:

    pip install sqlalchemy

    install sqlalchemy

    When using virtual environment or using Python 2
    pip install SQLAlchemy Flask-SQLAlchemy

    For python 3
    pip3 install SQLAlchemy Flask-SQLAlchemy

    If you get a permissions error
    sudo pip3 install SQLAlchemy Flask-SQLAlchemy
    pip install SQLAlchemy Flask-SQLAlchemy --user

    If you don’t have pip in your PATH environment variable
    python -m pip install SQLAlchemy Flask-SQLAlchemy

    For python 3
    python3 -m pip install SQLAlchemy Flask-SQLAlchemy

    When sing py alias
    py -m pip install SQLAlchemy Flask-SQLAlchemy

    For Jupyter Notebook
    !pip install SQLAlchemy Flask-SQLAlchemy

  3. Import the module

    Another reason for the error is that you forget to import the sqlalchemy. To import the module use the following line:

    import dataclasses

    import sqlalchemy

    This is also to check if the installation is successful at the same time to see if the error is resolved.

Causes of no module named ‘sqlalchemy’ Error

This error is frequently caused by one of the following factors:

  • Missing or outdated installation: This error may occur if SQLAlchemy is not installed or if it is an outdated version. Using pip, you can install or upgrade SQLAlchemy.
  • Incorrect module name: This error may occur if you misspelled the module name in your code or imported the incorrect module name. Make sure you’re importing the correct module name.
  • Incorrect Python environment: This error may occur if you are using a virtual environment or a specific Python version that does not have SQLAlchemy installed. Make sure SQLAlchemy is installed in the correct environment.
  • Missing dependencies: SQLAlchemy may rely on other Python modules that are not installed.
