Poetry 1.3 dies when run with a TTY reporting size 0/0

• Poetry version: 1.3.1
• Python version: 3.10
• OS version and name: Ubuntu 20.04
• pyproject.toml: pyproject.toml

• I am on the latest stable Poetry version, installed using a recommended method.
• I have searched the issues of this repo and believe that this is not a duplicate.
• I have consulted the FAQ and blog for any relevant entries or release notes.
• If an exception occurs when executing a command, I executed it again in debug mode (-vvv option) and have included the output below.

Issue

Running as part of a circle ci workflow. Steps below. The command poetry install identifies the Package Operations and then exits with code 1. (output below) SSH into the box and running poetry install produces the normal expected behavior.

FYI a workaround is to run with --no-ansi as I stumbled upon this error and then while debugging used that option to clear up some of the output and things ran succesfully.

@rlgomes you’ve fixed our work deployment pipeline! Thanks. --no-ansi makes poetry install work as intended, on the cimg/python:3.8 docker image at least.
