Does not install on mac with homebrew python

[winni2k]

When I follow the installation instructions on my mac OS 10.13.4 using the following command:

pushd /usr/local/bin 
ln -s pip3 pip
popd
curl -sSL https://raw.githubusercontent.com/sdispater/poetry/master/get-poetry.py | python3

then I get the following error message:

I tried installing the package via pip3 directly, but that does not install a poetry executable. If instead I try to run the package`s main function then I get this error message:

$ python3 -mpoetry
/usr/local/opt/python/bin/python3.6: No module named poetry.__main__; 'poetry' is a package and cannot be directly executed

Any ideas on how to get this to work?

Which pip version do you have?

[winni2k]

$ pip --version
pip 9.0.3 from /usr/local/lib/python3.6/site-packages (python 3.6)

[sdispater]

Could you download the get-poetry.py and execute it directly? To see if that changes things.

[winni2k]

$ python3 get-poetry.py

I just updated the get-poetry.py script to get more detail about the error.

Could you reexecute it to see what the pip error actually is?

Apparently this is a known problem with Homberew Python. See: https://stackoverflow.com/a/24357384

I recommend using pyenv to manage your python versions.

[winni2k]

Ok, as I don't have this problem with pipenv, I'll just stick with that for now.

I'll give poetry another shot when this issue gets resolved.

[sdispater]

@winni2k I won't be able to resolve this issue since it is not caused by poetry but by how homebrew install Python versions.

[winni2k]

Fair enough. The more I read about homebrew python, the more it looks like pyenv is probably a saner solution.
