Hi Luigi,

I have tried installing as per your instructions and it indicates that it
installed successfully as shown below;

ngonifungura@Ngonis-MBP ~ % pip3 install QuantLib

Collecting QuantLib

  Using cached QuantLib-1.20-cp38-cp38-macosx_10_9_x86_64.whl (14.7 MB)

Installing collected packages: QuantLib

Successfully installed QuantLib-1.20

ngonifungura@Ngonis-MBP ~ % pip3 install QuantLib-Python

Collecting QuantLib-Python

  Using cached QuantLib_Python-1.18-py2.py3-none-any.whl (1.4 kB)

Requirement already satisfied: QuantLib in
/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/site-packages
(from QuantLib-Python) (1.20)

Installing collected packages: QuantLib-Python

Successfully installed QuantLib-Python-1.18

However, I am still getting the error message that "No module named
'QuantLib'" when I try to run a valuation in Python

Kind regards,

Ngoni
