# ImportError: cannot import name 'Client' from 'twilio.rest' (unknown location)

## The problem

On Windows, installing twilio-python 6.36.0 via pip and then running `from twilio.rest import Client` fails with `ImportError: cannot import name 'Client' from 'twilio.rest' (unknown location)`. The import path reports as unknown location even though the package installed without a visible error. Python 3.8.2 was in use.

## The verified fix

This is caused by Windows' default 260-character MAX_PATH limit. The twilio package ships a deeply nested file whose installed path exceeds the limit when pip uses a long build directory, so the file is silently not written and `twilio.rest.Client` cannot be found. Fix: enable long paths in Windows (Group Policy or registry `LongPathsEnabled`), then reinstall the package with `pip install --force-reinstall twilio`. The install will then complete fully and the import works.
