src/{{cookiecutter-package}} layout breaks CLI module

[egberts]

• Date you used Cookiecutter PyPackage: Dec 10-12, 2018
• Cookiecutter version used, if any: 1.60
• Python version, if any: Python3.5 (and Python 3.7)
• Operating System: MacOSX (and Linux/Debian 9/Stretch)

Description

This is my attempt to use the Python project template with the following characteristics:

• tests directory is outside of package
• package name is under src subdirectory

As outline in this commonly read Python article on directory layouts in https://blog.ionelmc.ro/2014/05/25/python-packaging/.

But I cannot get the {{cookiecutter-package}}.cli module to be import-able into python CLI session (or from any Python script having such said import statement.

Strangely, all other packages modules under src/reconfigure were import-able, just not CLI.

What I Did

Error looks like:

$ cd ~/work/python/junk
$ python3 -m venv env3
$ cd env3
$ source bin/activate
$ git clone https://github.com/audreyr/cookiecutter.git
$ cd cookiecutter
$ python3 setup.py build
$ python3 setup.py install
$ hash -r
$ cookiecutter --version
1.6.0
$ cookiecutter https://github.com/audreyr/cookiecutter-pypackage.git

(env3) ~/work/python/junk/env3$

This is the part where I push the package subdirectory down the newly created src directory.

(env3) ~/work/python/junk/env3$ cd reconfigure
(env3) ~/work/python/junk/env3/reconfigure$ mkdir src
(env3) ~/work/python/junk/env3/reconfigure$ mv reconfigure src/

Final directory layout now looks like:

reconfigure
  |
  +-- docs
  +-- .github
  +-- .eggs
  +-- reconfigure.egg-info
  +-- src
  |    |
  |    +-- reconfigure.  # Python Installable Package
  +-- tests

Then build a basic CLI

(env3) ~/work/python/junk/env3/reconfigure3$ make distclean
(env3) ~/work/python/junk/env3/reconfigure$ python3 setup.py build
(env3) ~/work/python/junk/env3/reconfigure$ pip install -e .

Then onward to see if the CLI module is importable:
