When i start up new project, I sent command $ pipenv install for initializing default structure.
But no specific pypi-package-name passed, it raised above error.

However, when I pass pypi-package-name on start up, it works well:
$ pip env install requests.

how to deal with it ?

Is $ pipenv install (blank) bad request?
