When creating new project (== installing first dependency), I’m getting a FileNotFound exception:

$ pipenv install pelican

Pipenv was installed with pipsi (as per documentation), and this happen on versions 3.3.0, 3.3.1 and latest master commit in the time of writing (7e6affc).

By my estimation, this problem lies in pipsi not installing/linking the pew CLI script.
