Fixing 'No Module Named' Error in Python Scripts

The 'No Module Named' error in Python occurs when the interpreter cannot locate the specified module required for your script.

This typically happens due to missing installations, incorrect environment setups, or unresolved dependencies.

To address this, start by checking the Python version you're using with python --version or python3 --version, as mismatched versions can lead to this error.

Then, verify the module's installation using pip list.

If it's not listed, install it with pip install <module_name> or pip3 install <module_name> depending on your environment.

For virtual environments, ensure you're activating the correct one before running commands.

If the module is installed but still not found, the issue might stem from a misconfigured PYTHONPATH or installation directory.

In such cases, use tools like which python or pip show <module_name> to locate the correct paths.

This error can also occur when using IDEs like PyCharm, so confirm that the IDE's interpreter matches the project's configuration.

Managing dependencies with tools like Poetry or virtualenv ensures a cleaner setup, while consistent debugging helps identify and eliminate path-related issues.
