poetry: Package zipp (3.1.0) not found.

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).

OS version and name: 10.14.6+macOS Mojave
Poetry version: 1.0.5

Issue

I tried to install the my pyproject.toml, but it fails. The following error occurs.

[PackageNotFound]
Package zipp (3.1.0) not found.

I checked the zipp can be installed via pip by pip install zipp==3.1.0.

How can I install it?

The result in debug mode

Shouldn’t poetry check if a mirror is down, give some specific error rather than “package not found?”

Same issue on Alpine linux, Poetry 1.0.5 with Python 3.8.2 Many packages not found, and the request to pypi.org/pypi return status code 503. pip install successfully, but pip search will follows: “get pip._vendor.requests.exceptions.HTTPError: 503 Server Error: Backend is unhealthy for url: https://pypi.org/pypi”

It seems that it’s not the search issue that is affecting Poetry but rather the PyPI JSON API releases endpoints that are currently not working (For instance, while https://pypi.org/pypi/poetry/json works, https://pypi.org/pypi/poetry/1.0.5/json does not) which is why Poetry triggers the PackageNotFound error since the endpoint returns a 404 error.

sdispater on Mar 26, 2020

It seems that it’s now fixed on PyPI’s end.

sdispater on Mar 26, 2020

curl -I https://pypi.org/pypi returns 503 and sometimes 301, so I’d say this is a PyPI issue that affects poetry. Clearing the cache does not help; tested with poetry add pytd. However, it’s probably a good idea to do so once PyPI is up again.

jnik-aarhus on Mar 26, 2020

I can confirm pypi is back. Maybe poetry can throw a more explicit error, when pypi endpoints are down?

simion on Mar 26, 2020

This is really annoying, is there any workaround?

$ pip install --user devpi-server
$ devpi-init
$ devpi-server

# second terminal
$ PIP_INDEX_URL=http://127.0.0.1:3141/root/pypi/+simple poetry add asyncio

That’s simplified version of https://devpi.net/docs/devpi/devpi/stable/+d/quickstart-pypimirror.html

infotim on Mar 26, 2020

Yes, it is caused by a PyPI error but:

The error is very confusing
Using pip or pipenv to manage library still works, and we’re being stuck because we use Poetry.

I’m not familiar with the code base but why does Poetry need to use pip search?

nbarraille on Mar 26, 2020

This is what PyPI is at the moment. So poetry is not at fault here.

The latest versions shows up correctly on poetry show--outdated.

This is a serious bug, it’s blocking us from upgrading our project 😦
