Python / pandas - Replit Boilerplate Error

The boilerplate for the Demographic Data Analyzer project is not running on Replit. It appears to fail while attempting to install a version of pandas (1.3.0) that was released yesterday (July 2).

Python 3.8.2 (default, Feb 26 2020, 02:56:10)

Challenge: Demographic Data Analyzer

Link to the challenge:

This was reported at poetry’s repository - RuntimeError - Unable to find installation candidates for pandas (1.3.0) · Issue #4250 · python-poetry/poetry · GitHub.

Problem can be bypassed by explicitly installing different version of pandas using shell, i.e.
poetry add pandas@1.2.5

There was a similar question.
Check the recently reported problem in StackOverflow:

Just try to make the installation through the source.

Making pandas from source is really impractical on repl, IMHO

This issue has been resolved. I made no changes to the boilerplate; just waited a couple of days.
