What's the problem this feature will solve?

I try to run pip install -r requirements.txt but I'd like one of the packages to be installed without dependencies.

Describe the solution you'd like

Make --no-deps flag work inside requirements.txt

I use AWS Elastic Beanstalk's Python platform. It installs all the packages from requirements.txt during deployment of user's code. One of the packages I use is aiopg and I don't want it to install psycopg2-binary since it is not recommended for use in production. I have the original psycopg2 package in requirements.txt along with another aiopg's dependency async-timeout and that should be enough for aiopg to work smoothly.

Alternative Solutions

I can't find any workaround for this problem.
