My script stasrts as follows:

from smartcard.Exceptions import NoCardException
from smartcard.System import readers
from smartcard.util import toHexString

I have been developing using spyder and the script runs fine.

When I attempt to run at hyper command line, I get the following:

smart.py", line 16, in <module>
    from smartcard.Exceptions import NoCardException        
ModuleNotFoundError: No module named 'smartcard'

When I check to see if pyscard is installed, I get the following:

$ pip install pyscard
Requirement already satisfied: pyscard in c:python311libsite-packages (2.0.10)

How can pyscard be installed and not be installed on execution?
