poetry: FileNotFound error when installing packages when console script same name as package for Python 2.7

• I am on the latest Poetry version.
• I have searched the issues of this repo and believe that this is not a duplicate.
• If an exception occurs when executing a command, I executed it again in debug mode (-vvv option).

• OS version and name: Ubuntu 20.04
• Poetry version: 1.1.3
• Link of a Gist with the contents of your pyproject.toml file:

Issue

If I have a console script with the same name as the package, I get a FileNotFound error when I do poetry install in a python 2.7 virtualenv:

$ poetry init mytest
# Put the pyproject.toml from my gist in the root directory of the package
# Put the main.py from my gist in the mytest directory
$ poetry update
$ poetry env use 2.7
$ poetry install -vvv
