Poetry: `poetry run` behaves incorrectly

[sobolevn]

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

• OS version and name: macos 10.14.1
• Poetry version: 0.12.8

Issue

poetry behaves incorrectly when I try to run poetry run whatever_command. There are different usecases I want to show.

Just getting the help

» poetry run --help

[FileNotFoundError]
[Errno 2] No such file or directory: '/Users/sobolev/Documents/github/wemake-djang
o-template/.venv/bin/--help': '/Users/sobolev/Documents/github/wemake-django-templ
ate/.venv/bin/--help'

run <args> (<args>)...

The same with debug mode:

» poetry run --help -vvv

[FileNotFoundError]
[Errno 2] No such file or directory: '/Users/sobolev/Documents/github/wemake-djang
o-template/.venv/bin/--help': '/Users/sobolev/Documents/github/wemake-django-templ
ate/.venv/bin/--help'

run <args> (<args>)...

Getting python location

Now let's move to shell commands:

» poetry run which python

[FileNotFoundError]
[Errno 2] No such file or directory: '/Users/sobolev/Documents/github/wemake-djang
o-template/.venv/bin/which': '/Users/sobolev/Documents/github/wemake-django-templa
te/.venv/bin/which'

run <args> (<args>)...

Executing python binaries

This is working fine:

» poetry run python --version
Python 3.6.6

» poetry run pytest --version
This is pytest version 4.0.0, imported from /Users/sobolev/Documents/github/wemake-django-template/.venv/lib/python3.6/site-packages/pytest.py

Installation details

[sdispater]

There was a regression in 0.12.8. This is already fixed on master and I will make a new bugfix release on Monday.
