Issue

First of all, thank you for the great tool! 👏

I have an issue when trying to pip install a package I published in a private PyPI repository using poetry.

Below are the steps I've used to publish the library

$ poetry build

To reproduce the issue, I created a new virtual environment through pyenv, activated it, and finally tried to install the library via pip.

$ pyenv virtualenv myenv
$ pyenv activate myenv
$ python -V
Python 3.7.5
$ pip install -i https://pypi.prod.mypypi.us/simple/ bidding

I've tried this a bunch of times and the error message is the same, although the dependencies might change from time to time ― e.g., pandas, numpy, pystan.

@sdispater Can you see anything in the way I've built and published my library?

For the sake of completeness, I've also tried to install the dependency from a Python 3.6.5 environment and encountered the same exact issue.

Hello @IamGianluca
I am also using a private repository.
I have not tried publishing to it through poetry yet, but I install from it without any issue.

One difference I see is that I specify it in my pyproject.toml (doc for reference):

[[tool.poetry.source]]
name = "foo"
url = "https://foo.bar/simple/"

How does this behave in your case?

[pwoolvett]

What libraries does your private index have? I think the message you're getting is because pip cannot find the dependencies (pystan) of your library in the index you told it to use.

Have you tried running something like this?
pip install --index-url https://pypi.prod.mypypi.us/simple/ --extra-index-url https://pypi.org/ bidding

This way, pip can also look into the public pypi for all other packages.

If I'm right, another option would be to also upload your libary deps to your private repo...

@romaingz would not have this issue because the the command poetry runs internally already does this:

Command ['...pip', 'install', '--no-deps', '--index-url', 'https://pypi.prod.mypypi.us/simple', '--extra-index-url', 'https://pypi.org/', 'bidding==...'

[IamGianluca]

Thank you for your reply @pwoolvett !

As you pointed out, the issue was that my private repository did have a copy of the dependencies needed by my library. I had to make a minor change to the command you suggested, but now it works!

$ pip install --index-url https://pypi.prod.mypypi.us/simple/ --extra-index-url https://pypi.org/simple bidding
