I guess I don't completely understand the concept after all. If I setup a virtual environment for 3.9.6, how would it "know" that modules are installed in the 3.8 directory? As I wrote in my original post, without a virtual environment, in 3.9.6 I get:
>>> import scapy Traceback (most recent call last): File "<stdin>", line 1, in <module> ModuleNotFoundError: No module named 'scapy' but the module does exist in 3.8: sudo pip3 install scapy Requirement already satisfied: scapy in /usr/local/lib/python3.8/dist-packages (2.4.4) So how do I tell the 3.9.6 environment to look for modules in the 3.8 directory?
