Poetry config - command: poetry not found, but path added to bashrc and shrc files. export path command caused directory error running script - python-poetry

Question

I am a new linux/python user trying to get poetry set up. Basically I can make the poetry command work by using the export path statement, but that only causes a directory issue when executing script. Ive downloaded poetry using the command:
curl -sSL https://raw.githubusercontent.com/python-poetry/poetry/master/get-poetry.py | python -
I know that it's installed because if I try and run that again, it says it already downloaded. I run into the error:
command: poetry not found
I used
nano ./bashrc
nano ./shrc
in terminal and I've edited both of those with
export PATH="$HOME/.poetry/bin:$PATH"
then, I'm following instructions to run a set of scripts under directory "thermalproc" that I've been given, and the path is ~/Desktop/VideoProcessing/thermalproc-20220625/thermalproc . I'm to use the command
poetry run thermalproc
the only thing that I have done to make the command work is to use that export line directly in the terminal, and that does allow the command to work, but if i run just the command as so:
joshua#Andrea-G750JZA:~$ poetry run thermalproc
it returns
RuntimeError
Poetry could not find a pyproject.toml file in /home/joshua or its parents

→ 369│ raise RuntimeError(
370│ "Poetry could not find a pyproject.toml file in {} or its parents".format(
371│ cwd
372│ )
373│ )
and if I run in the directory of the script as I originally thought I should:
joshua#Andrea-G750JZA:~/Desktop/VideoProcessing/thermalproc-20220625/thermalproc$ poetry run thermalproc.
FileNotFoundError

Thanks for sticking it out this long, any advice would be greatly appreciated!
