Issue

This is related to #1377 but for this issue it's running on bare metal or developer machines.

Steps to Reproduce:

1. Use Python 3.8.0 as local system version using pyenv.
2. Run curl -sSL https://raw.githubusercontent.com/sdispater/poetry/master/get-poetry.py | python
3. Run poetry or any poetry command and see:

Traceback (most recent call last):
  File "/Users/USERNAME/.poetry/bin/poetry", line 12, in <module>
    from poetry.console import main
  File "/Users/USERNAME/.poetry/lib/poetry/console/__init__.py", line 1, in <module>
    from .application import Application
  File "/Users/USERNAME/.poetry/lib/poetry/console/application.py", line 6, in <module>
    from cleo import Application as BaseApplication
ModuleNotFoundError: No module named 'cleo'

Hello @lassiter,

can you please try to install the latest preview version by

curl -sSL https://raw.githubusercontent.com/sdispater/poetry/master/get-poetry.py | python - --preview

I just tried installing poetry on a new machine with Python 3.8.0 and I get the same error. Will try the preview command above and report back with result.

Edit/Update: Tried installing with --preview and now it seems to work, or at least to the point where I can run the poetry command.

I have the same issue. The problem appears to simply be that the latest release tarball does not have a py3.8 directory under poetry/_vendor.

When I install the missing dependencies manually in the local environment, the release Poetry runs fine under Python 3.8, but this obviously defeats the purpose of vendorizing them.

I was able to run that command then source it, then run poetry which allowed me to see all of the commands.

Thanks for coming back and reporting.

So I (or you) can close this issue?

[lassiter]

@finswimmer Do you know when the preview is expected to be released?

Happy to close.

@lassiter Unfortunately I couldn't tell you date for this. There are still a few things to fix before the 1.0 release. See current state here: https://github.com/sdispater/poetry/projects/1

We hope we can release "soon" ;)
