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.

The issue is also present in poetry 1.0.0b1

[etijskens]

the issue happens both on macOS Catalina and ubuntu 19.10

[etijskens]

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.

[anandkamat05]

I am having the same issue installing packages such as scipy (version 1.4.1). Any suggestions?

@anandkamat05 The root cause of the issue from the original ticket has been clearly identified. It is a solved issue. Are you really having the same issue? Are you having an issue with micc? It seems like you are seeing a different issue, if any. Please post the full command and error message.
