Github Action/Ubuntu: add to PYTHONPATH

Question

On Github Action workflow main.yml, I did the following to add to PYTHONPATH

PWD=$(pwd)
export PYTHONPATH=$PWD/src:$PWD/tests:$PYTHONPATH

I verified the PYTHONPATH using the following command

echo "PYTHONPATH=$PYTHONPATH"

and the output is PYTHONPATH=/home/runner/work/my_api/my_api/src:/home/runner/work/my_api/my_api/tests

I have a module called my_api live under /home/runner/work/my_api/my_api/src

But now I'm getting ModuleNotFoundError: No module named 'my_api' It seems export PYTHONPATH has no impact on the system. Below is the complete workfile YML file.

          ls src/

          echo "----PYTHONPATH------"
          PWD=$(pwd)
          export PYTHONPATH=$PWD/src:$PWD/tests:$PYTHONPATH
          echo "PYTHONPATH=$PYTHONPATH"

          echo "-----HISTORIC PATH----"
          export HISTORIC_DATA_FOLDER=/home/runner/work/my_api/my_api/my_api_historic_data_test
          echo "HISTORIC_DATA_FOLDER=$HISTORIC_DATA_FOLDER"

As already said in comments, each step runs in it's own shell. You need to make sure your variable is exported properly, so that it's available in all subsequent steps.

echo "PYTHONPATH=$PYTHONPATH" >> $GITHUB_ENV

See docs for more details.
