pipenv fails to install Jupyter in a Python3 environment when Python2 is present

[nsecord]

Describe the issue briefly here.

pipenv fails to install jupyter in a newly created Python 3 environment when Python 2 is also present

Environment

OS Type : macOS Sierra 10.12.6
Python version: both Python2 and Python3 (installed and updated via homebrew)

Python 2

$ which python 
/usr/local/bin/python
$ python --version
Python 2.7.14

Python 3

$ which python3
/usr/local/bin/python3
$ python --version
Python 3.6.3

Pip2

$ which pip
/usr/local/bin/pip
$ pip --version
pip 9.0.1 from /usr/local/lib/python2.7/site-packages (python 2.7)

Pip3

$ which pip3
/usr/local/bin/pip3
$ pip3 --version
pip 9.0.1 from /usr/local/lib/python3.6/site-packages (python 3.6)

Pipenv

$ which pipenv
/usr/local/bin/pipenv
$ pipenv --version
pipenv, version 8.2.7

Expected result

It seems that if you want to install Jupyter for a Python3 environment, it wants to be installed using pip3 explicitly (at least that is what they say in the installation instructions).

If I understand correctly, pipenv will invoke pip to do the package installation but if you have a legacy Python2 installation, pip will point to pip2. So what do you do in this case when you want to create a Python3 environment?

My expectation was that when I create a new environment with pipenv --three, it should invoke pip3 each time I install a package via pipenv install package. It doesn't seem to be the case or am I doing something wrong?

Actual result

See failure message below.

If I run pip install --three jupyter, it removes the existing Python3 environment, creates a new Python3 environment and then I get the same error message again.

If I remove the Pipfile, delete the environment and redo using Python 2, everything runs smoothly and installs.

@nsecord your assumptions are correct, and actually pipenv does this correctly. Note that in the first instance you saw:

The issue is with how pip-tools, the package we use for resolving Pipfile.lock, handles its resolution. Specifically with python 2 based installs of pipenv, pip-tools has trouble managing dependency resolution when installing python 3 based virtualenvs. This is a known issue and can be resolved by uninstalling pipenv and reinstalling it with pip3 install pipenv3 or pip3 install pipenv --user

[nsecord]

@techalchemy thank you for your response, I'll try what you have suggested. One question, by installing pipenv using pip3, will I run into problems in the opposite sense if I should need to create a Python 2 environment?

[techalchemy]

@nsecord you shouldn't encounter this problem going in the other direction, so this should be a simple temporary fix.

[erinxocon]

In my experience Python 3 doing stuff to python 2 stuff is a lot easier than python 2 doing stuff to python 3 stuff. A very well put together sentence I know, but ya'll get the point!

@techalchemy

I have the same old issue with jupyter and ipython: https://github.com/wemake-services/wemake-django-template/issues/4

When trying your fix:

» pip3 install pipenv3
Collecting pipenv3
  Could not find a version that satisfies the requirement pipenv3 (from versions: )
No matching distribution found for pipenv3

Are you sure that this distribution exists? Or should I add an external PyPI for that?

[sobolevn]

After installing pipenv with pip3 instead of pipsi I was able to install ipython! Wow!

@sobolevn there is no pipenv3 but if you use pip3 to install pipenv as you seem to have figured out it should provide some resolution. I'm going to go ahead and close this out since we have a resolution for now and the underlying issue is being tracked in #857

Installing pipenv with pip3 did the trick. Thanks.

This is a known issue and can be resolved by uninstalling pipenv and reinstalling it with pip3 install pipenv3 or pip3 install pipenv --user

I'm having the same problem but I'm a novice. How do you reinstall it with 'pip3 install pipenv3'?
