Is there a way of forcing Calibre to use "system" Python?

AlPe · 07-31-2013, 11:14 AM

Hi all,

in view of this problem, I am trying to understand whether there is a way of making Calibre to use the "system" installation of Python (in my case, Windows 32bit + Python 2.7.5) instead of the bundled Python libs (in my case, Windows 32bit + Python 2.7.4).

From my tests, it seems not possible, but I would like a confirmation from the experts. Alternatively, I would appreciate if the next Calibre for Windows will ship Python 2.7.5, since Python 2.7.4 is full of regression bugs at key libraries, like zipfile.

Thanks.

Use calibre.utils.zipfile instead of zipfile.

The python stdlib zipfile is badly broken and has always been badly broken.

Thanks for the quick reply.

From a quick test, your suggestion seems to work perfectly, and I appreciate the fact that I just need to change the import lines
