python3's pipenv, is only creating python3 shell,even though the parameter --two is passed. .Do we need to install pipenv for both python?

campaign_response sidvis$ pipenv --two shell
:
✔ Successfully created virtual environment! 
:
(campaign_response) bash-3.2$

Now the pipenv campaign_response is setup! But it fails because of python3.6 dependencies.

(campaign_response) bash-3.2$ pipenv install x

    from typing import TYPE_CHECKING
  File "/anaconda3/lib/python3.6/site-packages/typing.py", line 133
    def __new__(cls, name, bases, namespace, *, _root=False):

And python3 comes as defaulty python:

(campaign_response) bash-3.2$ python
Python 3.6.4 |Anaconda, Inc.| (default, Jan 16 2018, 12:04:33)

Solution

The reason it was happening was because pipenv was picking python3 pipenv.oops! you need to use a lib in python2 pipenv by passing it as: python2 -m pipenv install x
