Hi team I have created deb package of my code where I am using all dependency but still I am getting this error

Previewing update (pulumi-test):

If I go and check my python env then I am not getting any import error

root@b43ba04ea07e:/# /opt/ns/python-apps/resourcecreation/app-env/bin/python

>>> import pulumi
>>>

In this I am not getting this error but I have created API which will call the CLI so I am executing my code on my machine

/opt/ns/python-apps/resourcecreation/app-env/bin/python /opt/ns/python-apps/resourcecreation/app-env/lib/python3.7/site-packages/resourcecreation/app.py

Then I am getting error So Can any one tell me is it any way that while calling pulumi commands I point my python binary instead of taking machine default binary?
