modulenotfounderror: no module named src [SOLVED]

In this post, you will learn the solutions to solve the error Modulenotfounderror: no module named ‘src’.

Actually, all programmers in python may encounter this error because the Python interpreter cannot find a module that your code is trying to import from a subdirectory named “src”

What is src in Python?

In Python, “src” is not a built-in keyword or function. It is mostly used as a shortcut of “source”, which refers to the source code of a program or module.

What are the possible reasons for this error no module named src?

The possible reasons for this error no module named src which are the following:

The module you are trying to import does not exist.
The module is located in a subdirectory named “src” and you forget to include the subdirectory in the import statement.
The module is located in a virtual environment or in a conda environment which is not currently activated.
The subdirectory named “src” does not exist in the directory where your Python script is located.
The subdirectory named “src” exists, but it is not on your Python path.
You misspelled the name of the module when you were trying to import it.
The module that you are trying to import is haven’t been installed on your system.
You are running your script from a different directory than the one where the script and “src” directory are located.

How to solve the error Modulenotfounderror: no module named ‘src’?

Time needed: 3 minutes

Here are the following solutions to solve the error Modulenotfounderror: no module named ‘src’

Step 1: Check the Import the module name correctly.
First, Double-check that the module you are trying to import exists and that you have spelled the module name correctly.
Step 2: Check if the ‘src’ is in the correct directory
Second, Check if the module is located in a subdirectory named “src” and include the subdirectory in the import statement.

Add the “src” directory to your Python path.
Step 3: Activate the correct virtual environment
Third, Activate the correct virtual environment or conda environment if the module is located in an environment.
Step 4: Module ‘src’ is installed in the correct environment.
Last but not the least, If you are using a package manager like pip or conda.

Make sure that the module is installed and that you have installed it in the correct environment.

Frequently Asked Questions

What is Python ModuleNotFoundError and what causes it?

ModuleNotFoundError (a subclass of ImportError) is raised when Python cannot find the module you tried to import. Common causes: the package isn’t installed (pip install missing), wrong virtual environment activated, typo in module name, or Python can’t find your local module on the import path. The error message names exactly which module is missing.

How do I fix ‘ModuleNotFoundError: No module named X’?

Run pip install X first. If that succeeds but you still get the error, check which Python you’re using (which python OR python –version) vs which pip (which pip OR pip –version), they must match. Common gotcha: pip points to system Python 3.9 but you’re running python3.11 in a venv. Inside the venv, use python -m pip install X to be sure pip matches the active Python.

Why does my code work in one environment but not another?

Different Python versions or different installed packages. To diagnose: pip freeze > requirements.txt on the working environment, then pip install -r requirements.txt on the broken one. Use virtualenv (python -m venv venv) or conda for every project to avoid system-wide package collisions.

Is ModuleNotFoundError the same as ImportError?

ModuleNotFoundError is a subclass of ImportError added in Python 3.6. It specifically means ‘no such module exists.’ Plain ImportError covers a wider set: module exists but a name inside it can’t be imported (e.g. ‘cannot import name X from Y’). except ImportError catches both; except ModuleNotFoundError catches only the missing-module case.
