You should 'install' into the venv using pip after activating the venv. The weewx venv needs only the modules needed for your weewx setup to work, 'not' all the modules you might have installed at the os level. Everybody's answer might differ based on what extensions/skins etc. they have added to weewx itself.
But just as an example, for my weewx v5 setup here running 5.0.0b12.....
