How to Fix Python ImportError: No module named XXX in PyCharm Projects

Problem

When running a Python project in PyCharm, you may encounter the error ImportError: No module named XXX . The IDE can navigate to the file, but execution fails because the module cannot be found.

Solution

1. At the top of the affected .py file, add the project’s root directory to the import path. For example:

import sys
import os
sys.path.append(os.path.abspath(os.path.join(os.path.dirname(__file__), '..')))

2. Verify and adjust the Working Directory of the run configuration. Ensure it points to the correct project folder.

3. Double‑check that PyCharm’s automatically generated file references are accurate; sometimes they may point to the wrong location.
