Windows: cannot find pythonxx.dll about nimpy

[yglukhov]

Nimpy tries to find a suitable python dll among those already linked to current process. Insert an echo "Candidate: ", fn here: https://github.com/yglukhov/nimpy/blob/master/nimpy.nim#L572, and see how your python.dll is actually named.

I got

<344 lines in total - mostly python36.exe>

which has python36.dll - so what's not working?

[yglukhov]

Ah i see, try replace find with rfind here: https://github.com/yglukhov/nimpy/blob/master/nimpy.nim#L573

[raghur]

I think it's because the path has python earlier; replacing find with rfind in L573 seems to find the right dll.

EDIT: you beat me to the comment
