I am trying to run a simple flask application with python3.5 but getting below error.
SyntaxError: future feature annotations is not defined
i have installed the latest version of flask using below command.
RUN pip3 --trusted-host=pypi.python.org --trusted-host=pypi.org --trusted-host=files.pythonhosted.org install Flask gunicorn wheel
Please suggest how to fix this issue.
