Python: OSError: cannot load library libcairo.so.2

I'm having some trouble running a python script on my Windows 7 platform. I've installed Python and also cairo, last one using "pip". I'm running the script using this command:

C:\Python34>python.exe label/make_label.py

and I get the following error message:

Traceback (most recent call last):
  File "label/make_label.py", line 6, in <module>
    import cairocffi as cairo

OSError: cannot load library libcairo.so.2: error 0x7e

What I've already done is the following:

• Added the PATH to GTK/bin in the environmental variable
• I check the folder GTK/bin and found "libcairo-2.dll" so I renamed it to libcairo.so

I don't know what other information could be useful in solving this but please let me know and I'll try to add it.

It seems cairo depends a shared library which is not in standard search library, however, the python is calling dlopen to dynamic load the library, so you could try to put the libcairo.so.2(if it's a link, then make sure the reference locates at the same folder) in the working directory. You can also try pkg-config to set the environment. see here http://people.freedesktop.org/~dbn/pkg-config-guide.html
