When I run the Django server, I see this problem !!
OSError: no library called "cairo" was found
no library called "libcairo-2" was found
cannot load library 'libcairo.so': error 0x7e
cannot load library 'libcairo.2.dylib': error 0x
cannot load library 'libcairo-2.dll': error 0x7e
Installing GTK+ didn't work for me. I solved this problem using UniConverter2.0. My environments is
C:\Program Files\UniConvertor-2.0rc4\dlls
