回答1:

To run pip for python3 use pip3, not pip.

Another solution.

You can add this line (after apt-get install). It will upgrade pip to the version you need, for instance:

RUN pip3 install --upgrade pip==20.0.1

and you can then use pip install from requirements file (for instance):

RUN pip install -r requirements.txt
