poetry env doesn't work on Windows after install-poetry.py

• 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).

Issue

After installing poetry, creating a fresh project and running poetry env list the following error occurs:

EnvCommandError

Command python -W ignore - errored with the following return code 1, and output:
'python' is not recognized as an internal or external command,
operable program or batch file.
input was : import sys

if hasattr(sys, "real_prefix"):
    print(sys.real_prefix)
elif hasattr(sys, "base_prefix"):
    print(sys.base_prefix)
else:
    print(sys.prefix)

    1181│                 )

    1186│
    1187│     def execute(self, bin, *args, **kwargs):

This appears to be due to the following at lines 1233-1236 in https://github.com/python-poetry/poetry/blob/1.1/poetry/utils/env.py:

            if not bin.endswith(".exe"):
                bin_path = self._bin_dir / (bin + ".exe")
            else:
                bin_path = self._path / bin

I believe in the first case self._path should be used instead of self._bin_dir.

This problem doesn't appear to happen (the function is never called) when poetry is installed with get-poetry.py instead of install-poetry.py. I don't know why that is, but it's a good workaround. I think the above code is wrong nonetheless.

FWIW this problem appears to have begun in 1.1.9.

@tom-bowles great research. Poetry 1.1.8 works for me too, the latest version still seems to be broken.

With apologies, I'm pinging the 4 members of the python-poetry project since the "@python-poetry/triage" as mentioned in the docs doesn't work: @sdispater @abn @finswimmer @stephsamson

This issue has been present since 1.1.9 and renders poetry unusable on Windows. It's a simple typo with a one-line fix.

Any timeline on when this will be resolved?

Have you tried installing poetry with pipx at all, does that get around this issue?

tried and the answer is no...
i think this is also related to issue #2117

Closing as duplicate of #2117.
