Concerning this "venv":

I am not programming anything at all using python....
I cannot understand that language.

But I am using utilities that are downloaded/installed on my Linux machine using
whatever install mechanism the utility suggests. Many of these seem to be
written using python, but taht is not very much advertised when getting the
utility.
Of course pip suggests tyhat we are dealing with a python utility, but apt does
not.

In the case of streamlink it turns out that the version one gets when using apt
to install it (apt being my first source for utility installs) is WAY lower than
the version when using pip to install it. Like going from major version 3 to
major version 6!

When it is installed I am assuming it is available for general use as long as
the executable is on path. So it should not depend on in which direcvtory one
issues the command.

Reading the replies here makes me believe that the venv thing makes a utility
only work if it is launched inside a specific directory on the disk, and that is
not what I want.

I launch my utilities from 'cron' or 'at' or from whatever user dir I happen to
be inside with a terminal and I expect it to work the same everywhere...
