Re: [Quantlib-users] Failed to import QuantLib library in python

[Luigi B. <lui...@gm...>]

I don't think there is.  You'll probably have to remove the
*build/bdist.macosx-10.15-x86_64/egg/
*directory.  To be sure you're not missing anything, you might also run
"pip uninstall QuantLib-Python" first, then look for anything related to
QuantLib in /usr/local/lib and its Python subdirectories.  Once you clean
them (but be careful to only clean stuff with "quantlib" in its name), you
can run "pip install" again.
