Question

* 1. Download the Windows installer from the PIL website.
* 2. Double click on the installer to start the installation process.
* 3. Choose the correct directory for PIL install.
* 4. Finish the installation and test out our sample application locally.

These are instructions from google website.
but what is the “Choose the correct directory for PIL install.” correct directory?
is in the python lib? in the google app engine? or somewhere else?

I can’t get to work with images locally:

my code:

def upload(input):

items = input['items']

for item in items:
    img = images.resize(item['image'], 300, 300)


return img

I’ve installed the PIL in the c:\python dir and then I copyed the folder in my project root. still doesnt work! :s

the error I got is:

“D:\Totty\webDevelopment\TottysWorld\src\app\services\images\upload.py”, line 11, in upload
img = images.resize(item[‘image’], 300, 300)

Answer 1

PIL must be installed into the Python installation path. Let’s say you’ve installed Python 2.5 to C:\Python, then installation path for PIL should be ‘C:\Python\Lib\site-packages\’.

Also you don’t have to copy PIL directory to project root when you install it right into the python directory.
