QUESTION: pipenv "-e ." --dev works same way on pip and pip3?

This looks like a blog post or something but it’s a question, sorry for the verbose…

So I just started the development of a library in order to learn python, coming from a Java/JS envs and used to dependency managers I “discover” pipenv.

Before using pipenv I was making use of:

• python 2.7
• virtualenv, virtualenvwrapper
• pip

So I have this project structure (basically):

my_project
    |------->my_project (src code)
                      |-------> cli.py
    |-------> setup.py

my setup.py

from setuptools import setup

setup(
    name='my_project',
    version='0.1',
    py_modules=['my_project'],
    install_requires=['Click'],
    entry_points='''
    [console_scripts]
    my_project=my_project.cli:runnable
    '''
)

With this setup if I ran pip install --editable .

it installed my package under dev mode in the site-package directory from my virtualenv, so I was able to run my_project from terminal as a command.

If I follow the same process for pip3 and py3 it works the same way…

Now I’m trying to make use of pipenv so I removed my virtualenv, and create a new one with pipenv --three, so now I have a new virtualenv with py3, then I executed pipenv shell to get into that virtualenv created by pipenv.

To make sure all is good I ran python --version which outputs Python 3.6.2 which is the one declared on my Pipfile. So all good.

So here’s the thing… Following the instructions from pipenv (Editable Dependencies) I executed pipenv install '-e .' --dev

It appends this to my Pipfile

[dev-packages]
"-e ." = "*"

It installed everything and looks like all is good, but at the time of trying to execute my_project from terminal I got some errors:

Traceback (most recent call last):
  File "/Users/atrevino/.virtualenvs/my_project-rf5gIlFJ/bin/my_project", line 11, in <module>
    load_entry_point('my_project==0.1', 'console_scripts', 'my_project')()
  File "/Users/atrevino/.virtualenvs/my_project-rf5gIlFJ/lib/python3.6/site-packages/pkg_resources/__init__.py", line 570, in load_entry_point
    return get_distribution(dist).load_entry_point(group, name)
  File "/Users/atrevino/.virtualenvs/my_project-rf5gIlFJ/lib/python3.6/site-packages/pkg_resources/__init__.py", line 2751, in load_entry_point
    return ep.load()

    return self.resolve()
  File "/Users/atrevino/.virtualenvs/my_project-rf5gIlFJ/lib/python3.6/site-packages/pkg_resources/__init__.py", line 2411, in resolve
    module = __import__(self.module_name, fromlist=['__name__'], level=0)
ModuleNotFoundError: No module named 'my_project'

so is there a difference using py3 or py2 with pipenv install '-e .' --dev or maybe am I missing some configuration on my setup.py?

Again, sorry for the long post and have a great day!

Make sure you’re using the latest version! We fixed the syntax in the pipfile recently.
