Virtualenvwrapper.sh functions not available in bash shell

Question

I'm doing a new install of virtualenvwrapper, and for some reason after running virtualenvwrapper.sh it's functions aren't available.

$ virtualenvwrapper.sh
creating.....
$ workon
workon: command not found

I know that it's running, aside from the successful creation of all the VE files, I've wrapped some of the function definitions in echo "please get here" statements and they all get hit.

So: what?

Answer 1

Oh I see, the correct thing to do is:

$ source virtualenvwrapper.sh

it was on my PATH, and getting run in a subshell, I guess.
