Why doesn't Canopy Code Editor import packages installed via Canopy Command Prompt?

Question

Python

I feel in my gut that the question is absolutely basic and I do not exclude that the answer to it is contained right here , but even if so, this answer does not reach me.
The problem is this: I
installed Canopy as a virtual environment (i.e. without modifying PATH):
I install packages in the Canopy Command Prompt via easy_install and pip install;
when trying to import a package in the Canopy Code Editor, an error like this is generated:
import packagename
-------------------------------------------------- ----------------------------------------
ImportError Traceback (most recent call last)
in ( )
----> 1 import packagename
ImportError: No module named packagename
the installed package does not appear in the Package Manager list either.
Windows 8, Canopy 1.1.1 64 (free version).
