How to Resolve PyLint \'Unable to Import\' Error by Modifying PYTHONPATH?

Resolving PyLint "Unable to Import" Error by Modifying PYTHONPATH

When utilizing PyLint within Wing IDE on Windows, importing modules from subdirectories within a project can trigger the error "Unable to import 'X'." This error occurs because PyLint's default Python path does not include the project's root directory, where the top-level module is located.

To rectify this issue, two options are available:

1. Adjusting PYTHONPATH Environment Variable

• Open the Control Panel and navigate to "System and Security."
• Select "System" and click on "Advanced system settings."
• In the "Advanced" tab, click on the "Environment Variables" button.
• Under "User variables," find or create a new variable named "PYTHONPATH."
• Set the variable value to the directory path that includes the project's root directory.

2. Modifying ~/.pylintrc File

• Navigate to the user's home directory (~) and open the file ".pylintrc."
• Add the following line to the [MASTER] section:

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

• Replace "/path/to/root" with your project's root directory path.

Either of these methods should successfully resolve the "Unable to import" error by adding the necessary directories to PyLint's Python path, ensuring that it can locate and import modules as expected.
