Heroku: No matching distribution found for PIL==1.1.7

Question

I am trying to push on my Heroku app and getting error while installing PIL on server, I have tried by tweaking my requirements.txt as given below

Django==1.4.5
Fabric==1.4.3
--allow-all-external
--allow-unverified PIL
PIL==1.1.7
#Pillow==2.3.0

Also tried by adding parameters at start of requirements.txt as given below:

--allow-all-external
--allow-unverified PIL
Django==1.4.5
Fabric==1.4.3
PIL==1.1.7
#Pillow==2.3.0

this is failing with error:

Answer 1

Use Pillow instead of PIL. PIL is not maintained and has not had a new release since 2009. Pillow is a maintained fork.
