How to Resolve "Unable to Import" Errors in PyLint by Setting PYTHONPATH

When encountering the error "Unable to import X" while using PyLint, particularly for modules imported from a sub-directory, the root cause may lie within the Python path configuration.

Solution 1: Modifying the PYTHONPATH Environment Variable

One effective solution is to adjust the PYTHONPATH environment variable to incorporate the directory containing the import, ensuring that PyLint has visibility to the necessary modules.

Solution 2: Configuring ~/.pylintrc

Alternatively, you can modify the ~/.pylintrc file, which serves as PyLint's configuration. Append the line:

[MASTER]
init-hook='import sys; sys.path.append("/path/to/root")'

Ensure that the path specified is accurate and that you are utilizing the correct section identifier. In some PyLint versions, [MASTER] may need to be replaced with [General].

By implementing either of these solutions, PyLint will gain access to the required modules and resolve the "Unable to import" errors, enabling code analysis to proceed smoothly.
