Cannot install with pipenv

[nam-vu-360f-com]

I tried install using pipenv but failed

pipenv install -e git://github.com/better/irr#egg=irr

The error

ValueError: pipenv requires an #egg fragment for version controlled dependencies. Please install remote dependency in the form git://github.com/better/irr#egg=.

What is the work around for this?

From pipenv homepage in advance usage section here they list an example

The missing part is git+https:// instead of git://

pipenv install -e git+https://github.com/better/irr#egg=irr
