poetry install micc fails

[etijskens]

I discovered that
poetry install fails on micc. filed bug report #1492. The issue is there
for both poetry v0.12.17 and v1.0.0b1.

nobody reacted to the issue - gotta do it myself...
or abandon poetry...
which may be the right thing to do in view of the many open issues.

on the other hand, poetry has a very simple mechanism for custom builds, see issue 1351 and investing time in setuptools is perhaps wasted.

fixing the bug in poetry install micc is meaningless if it is not accepted by poetry. maybe I better look for a workaround, like archiving the templates directory and unarchiving it as an custom install step.

But then poetry still lacks an editable install...

We could use shutil.make_archive and shutil.unpack_archive for the workaround.
Is there a post-install hook in poetry?
There isn't. Moreover, it is unlikely to come ... See Support for custom commands and functions
I don't want to go down the road of manual post-install scripts
Probably got to stick to setuptools at least for some time.

The reason why poetry install fails on installing micc, is that poetry considered the templates directory as a Python package instead of a data directory, because it contains .py files. We can avoid this by replacing the py extension in these filenames with a cookiecutter variable {{cookiecutter.py}} and set the variable to "py".
Works as a charm! now poetry install no longer fails.
