Pillow install fails on Termux (libjpeg missing)

Description

pip install pillow fails on Termux with 'libjpeg not found' or similar compilation error.

Cause

Termux does not bundle libjpeg-turbo by default. Pillow compiles from source and requires the native library.

Fix

Install libjpeg-turbo via pkg before installing pip packages.

Code change

pip install pillow

pkg install libjpeg-turbo -y
pip install pillow
