Pipenv with Conda?

Question

I'm using Anaconda for my virtualenvs in win 10. I'm using git-bash .I've been reading about pipenv recently and decided to give it a try. I installed pipenv on my base conda python which is a version of python 2.7 using :

pip install pipenv

I can easily create a python environment using

conda create --name py3 python=3.6

but I tried:

$ pipenv install --three

which gave:

Warning: Python 3 was not found on your system…
You can specify specific versions of Python with:
  $ pipenv --python path\to\python
....\miniconda2\lib\site-packages\pipenv\_compat.py:86: ResourceWarning: Implicitly cleaning up <TemporaryDirectory 'c:\\users\\......\\appdata\\local\\temp\\pipenv-4_fzvq-requi
rements'>
  warnings.warn(warn_message, ResourceWarning)

Is it possible to use the 2 packages together?

Answer 1

You can setup Pipenv to use Conda's Python executable and site packages directory (ref).

pipenv --python=$(conda run which python) --site-packages

You can check if you are indeed using your Conda environment in Pipenv:

pipenv run python
>>> import sys
>>> sys.executable, sys.path
# <directories under your Conda environment>

With NumPy installed through Conda, but not Pipenv, you can see that Pipenv will still find NumPy.

conda install numpy
pipenv run python
>>> import numpy as np
>>> np.__file__
# <path under your Conda environment>

When you install NumPy through Pipenv, it will shadow Conda's installation of the the package.

pipenv install numpy
pipenv run python
>>> import numpy as np
>>> np.__file__
# <path under your Pipenv environment>

Answer 2

You can install pipenv within a conda environment initialized with python 3.

$ conda create -n pipenv-test python=3
$ source activate pipenv-test
(pipenv-test)$ pipenv install --python=/home/.../miniconda3/envs/pipenv-test/bin/python

To activate this project's virtualenv, run the following:
 $ pipenv shell

This seems to work for me but I haven't tested it extensively. Also, my base conda python is 3.6 and I'm using Ubuntu 16.04. I'm curious to hear whether this still gives you trouble.
