I am writing a python script that uses PIL library to resize an image.
Is it possible to see whether the user already has PIL installed on his machine, and if not, install it automatically (ask for admin password if needed)?

To see if its installed simply do the import inside a try except, if it throws the exception its not installed. – Paul Rooney Apr 08 '15 at 10:55

Install pip by running this setup script, then install Pillow a subset of PIL:
pip install Pillow

I ran the script and got the following exception: Installing collected packages: pip Exception: Traceback (most recent call last): File "/var/folders/vh/jcvrl0tx07b8klnvrbklmfmw0000gn/T/tmpq7Xmrd/pip.zip/pip/basecommand.py", line 246, in main status = self.run(options, args) File "/var/folders/vh/jcvrl0tx07b8klnvrbklmfmw0000gn/T/tmpq7Xmrd/pip.zip/pip/commands/install.py", line 352, in run root=options.root_path, File "/var/folders/vh/jcvrl0tx07b8klnvrbklmfmw0000gn/T/tmpq7Xmrd/pip.zip/pip/req/req_set.py", line 693, in install **kwargs – Nili Apr 08 '15 at 11:25

Im soure you know by now, but just for the record, you need to use sudo: `sudo pip install Pillow`. Also this should be marked as the correct answer since Pillow is a more modern fork of PIL. – Lucas Alonso Jan 28 '16 at 16:34

@MalikBrahimi running the script you suggested generated the errors I mentioned, so I can't mark it as an answer. – Nili Jan 31 '16 at 09:52

@Nili In the command line, enter `sudo apt-get install python-pip` – Malik Brahimi Jan 31 '16 at 16:43
