Re: [Quantlib-users] Failure to install QuantLib on macOS 11.0

[Ngonidzashe F. <ngo...@gm...>]

Hi Luigi,

Yes, I am using Python 3.8.

I ultimately managed to run the valuation in PyCharm but the valuation is
giving me an error when I run it in Spyder. Spyder updated to version 4.1.5
and I am not sure if this updated version has issues. It’s weird that
Quantlib is working in PyCharm and not Spyder.

I guess I now need to work with PyCharm.

Thanks for your help Luigi!

Kind regards,

Ngoni
