• Package Name: azure-identity
• Package Version: 1.4.0b6
• Operating System: Ubuntu 20.04
• Python Version: 3.8

Describe the bug
When using Poetry to manage a python project. Installing the current pre-release version of azure-identity fails with a max recursion depth error.

To Reproduce
Steps to reproduce the behavior:

1. Install poetry

   pip install poetry

2. Set up a new poetry project in an empty directory

   mkdir azure-identity-test
   poetry init -n # -n specifies non-interactive and uses defaults

3. Install the prerelease of azure-identity

   poetry add azure-identity --allow-prereleases

4. Observe the following output

   Creating virtualenv azure-identity-test-ZMyS48q3-py3.8 in /home/nzsmartie/.cache/pypoetry/virtualenvs
   Using version ^1.4.0-beta.6 for azure-identity
   
   Updating dependencies
   Resolving dependencies... (8.4s)
   
   [RecursionError]
   maximum recursion depth exceeded while calling a Python object
   

Expected behavior
The package would install without issues along with its dependencies.

Additional context
Poetry has difficulty with multiple same name dependencies with different version requirements: python-poetry/poetry#1238

When enabling verbosity as the package is installed. there's an almost never ending loop of the following issue being produced.

Different requirements found for portalocker (>=1.0,<2.0) and portalocker (>=1.6,<2.0).

as produced by:

poetry add azure-identity --allow-prereleases -vvv
