Requested (package) has different version in metadata · Issue #9203 · pypa/pip · GitHub

Describe the bug

In Airflow, we are experiencing problems when we are trying to use the PIP released 2 days ago which has the new resolver on by default.

ERROR: Requested oauthlib[signedtoken]>=1.0.0 from https://files.pythonhosted.org/packages/e5/54/4f96c51b171cf3a64a04b8c5167268803205bc5943b5cdf70bd770727b88/oauthlib-1.1.0-1.tar.gz#sha256=0f786c5573248a38efa86c48c59c0c93140ac836ab2a246aeefd8f9039e999ba (from jira->apache-airflow==1.10.13) has different version in metadata: '1.1.0'

How to reproduce

Setup an empty virtualenv for Python 3.6
Upgrade to latest pip: pip install --upgrade pip
pip --version should return 20.3
Run this command:

pip install "https://github.com/apache/airflow/archive/v1-10-test.tar.gz#egg=apache-airflow[all]" --constraint https://raw.githubusercontent.com/apache/airflow/constraints-1-10/constraints-3.6.txt

Observe the output. It will keep on finding good dependencies until

Apparently, metadata in published oauthlib 1.1.0-1 is wrong snd points to 1.1.0.

The same command with the legacy resolver works fine:

pip install --use-deprecated legacy-resolver "https://github.com/apache/airflow/archive/v1-10-test.tar.gz#egg=apache-airflow[all]" --constraint https://raw.githubusercontent.com/apache/airflow/constraints-1-10/constraints-3.6.txt

Expected behavior

I expect the resolver does not get broken by broken metadata.

I've opened similar issue oauthlib as I am not sure who can fix it: oauthlib/oauthlib#744
