@vineet4may thanks for the report! The message at the top says Package libffi was not found in the pkg-config search path. - can you check that you have libffi headers installed? If you are on ubuntu, this is libffi-dev package. Can you also check that installing cffi python module works?

[vineet4may]

@lopuhin Sir Thank you so much Sir. It works for me.
