   Not to ignore the above discussion, but for the benefit of anyone else using poetry on top of airflow in a workflow similar to the following who is experiencing issues with flask-openid:
   1. Use the official Airflow docker image
   2. Export requirements from poetry so we can use the Airflow constraints file
   3. Globally install on top of the base Airflow dependencies using the airflow constraints file to ensure we get what the Airflow team deems 'golden'
   
   I had to add `python3-openid` to our `poetry.toml` as above, but I _also_ had to remove `python-openid` from the output `requirements.txt`, otherwise we still had it floating around and causing issues. As the poetry issues (https://github.com/python-poetry/poetry/issues/1287) says, this is a problem with `flask-openid`, not poetry :
   
   ```dockerfile
   RUN export PYTHON_MAJOR_MINOR_VERSION=$(python -c 'import sys; print("%s.%s"% (sys.version_info.major, sys.version_info.minor))') \
     && AIRFLOW_MINOR_VERSION=$(echo "$AIRFLOW_VERSION" | cut -d "." -f 1)-$(echo "$AIRFLOW_VERSION" | cut -d "." -f 2) \
     && curl -sSL "https://raw.githubusercontent.com/apache/airflow/constraints-$AIRFLOW_MINOR_VERSION/constraints-$PYTHON_MAJOR_MINOR_VERSION.txt" > ./airflow-constraints.txt \
     && poetry export --without-hashes -f requirements.txt -o ./requirements.txt \
     # flask-openid does not correctly specify version constraints https://github.com/python-poetry/poetry/issues/1287
     && echo "remove python-openid from poetry packages as it's pulled in incorrectly by flask-openid" \
     && sed -i '/^python-openid==/d' ./requirements.txt \
     && pip install --user --no-cache-dir --upgrade pip==${PIP_VERSION} \
     && pip install --user --no-cache-dir --no-warn-script-location -r ./requirements.txt --constraint ./airflow-constraints.txt \
     && rm -rf ~/.cache ./requirements.txt ./airflow-constraints.txt
   ```
