install [–no-dev] [–dry-run] [-E|–extras EXTRAS] [–develop DEVELOP]

poetry complains that the file ‘micc/templates/package-base/{{cookiecutter/project_name}}/tests’ does not exist, which is correct, but this should be ‘micc/templates/package-base/{{cookiecutter.project_name}}/tests’ instead of ‘micc/templates/package-base/{{cookiecutter/project_name}}/tests’

I have no clue where the file name is going wrong. The file is part of a cookiecutter template and is part of the package. somewhere the dot between {{cookiecutter and project_name}} is replaced with a slash.

I had this happen to me in docker containers. Updating pip and trying again worked for me.

pip install -U pip
poetry install

poetry install fails on installing micc because it recognises the directory micc/templates(containing the cookiecutter templates) as a sub-package of micc rather than as a data directory. This is because micc/templates contains .pyfiles, This can be avoided by replacing the"py"extension in these filenames with a cookiecutter variable{{cookiecutter.py}}` and set the variable to “py”. Now the directory is no longer recognised as a sub-package.
