            AWS Elastic Beanstalk Python (3.8) platform: run additional pip command for a Python package with `--no-deps` flag aside from using `requirements.txt`
            Asked 2021-May-05 at 14:54

            There's this Python package called aiopg for working with the PostgreSQL database asynchronously. It has two dependencies - async-timeout and psycopg2-binary. I don't want it to install psycopg2-binary when using pip because I use the regular psycopg2 package. This is because the authors of psycopg2-binary do not recommend using it in production.

            This all does not create any problems working locally because I can add the desired dependency of aiopg to requirements.txt leaving out the undesired one, and then run two separate commands:

            1. pip install -r requirements.txt
            2. pip install aiopg --no-deps

            But when I push my project to Elastic Beanstalk it uses requirements.txt to install Python packages and I don't know how to run the additional pip command.

            I tried adding pip3 install aiopg --no-deps and also different variations of this command to eb.config (both to commands and container_commands sections) but to no avail.

            Right now my eb.config looks like so:

            I had spent a whole day trying to solve this problem before posting this question. But some time after posting this I googled for some more time, tried a couple other approaches and found a working solution.

            I changed the last line in my eb.config file shown in the question into command: /var/app/venv/.../bin/python -m pip install aiopg==1.2.1 --no-deps where ... should be replaced by the name of the directory sitting inside /var/app/venv/ in your Beanstalk's EC2 instance. ssh into one of your instances to find this directory or search for pip command in your eb-engine.log if you set up exporting logs into CloudWatch (you'll see the full path to your pip's env there).

            aiopg.Pool[1] expects the positional arguments

            dsn, minsize, maxsize, timeout

            You have given 5 positional arguments

            None, 1, 10, None, 5

            That's one argument too much.
