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

When I try to install this project on this certain machine, nothing happens. Verbose option does not show anything useful. Is there another way to debug this issue?

Can you run Poetry with -vvv --no-ansi and see what output you get?

I followed the recommendations in here: https://github.com/python-poetry/poetry/issues/7184 to use --no-ansi and it solved our issue.

I finally upgraded to 1.3.2 but still had the same issue. While digging around a little bit, I finally found a workaround.

I removed the bullet characters in https://github.com/python-poetry/poetry/blob/master/src/poetry/installation/executor.py#L245 and the following lines and poetry works again on this machine.

sorry for the delay, was not in the office for a few days.

Same thing happens for us, when running poetry install -vvv; echo $? from CodeFresh. We get the following:

1 being the exit code.
