I am a programmer with more than two years of python programming experience, often the debugging process may led me to the details of some details of python implementation, this is exciting : ) Now i face a problem, that is i want to install PIL on windows, but failed, the error messages tells that the python installation cannot find python information in the windows register, lol, this is true, since i got a zipped python and extract it the a directory, not using a msi file to install python. So how should i do in order to install PIL for my python environment? I find that PIL installation file is a zipped file with execution capability (is it of 7z format?) Now i can open this exe file using 7z, and there are lots of .py files there, with directory somewhat as follows: PLATLIB PIL\*.py PIL.pth (a plaintext file with content "PIL") SCRIPTS *.py so can i just extrat the py files to my python installation directory? then will PIL work correctly? (should i extract PIL\*.py to python_24\Lib\site-packages, and extract *.py to python_24\Scripts?) Will this work? since this have something to do with the implementation of Python, i come to this maillist and ask for help..... Hope i can receive some suggestions, Thank you :)
