Upgrade setuptools before installation in .readthedocs.yml

[jofmi]

Using a configuration file .readthedocs.yml, I want to upgrade setuptools to a higher version than the default before installing my package. However, the pip command of .readthedocs.yml only takes path as an argument, so how can I call pip to upgrade setuptools?

Here is what I would put into .readthedocs.yml, but I am missing a command where it says ????:

version: 2
formats: all
python:
  version: 3.7
  install:
    - method: pip
      ????: setuptools >= 46.4.0
    - method: pip
      path: .

@JoelForamitti you can use a requirements file https://docs.readthedocs.io/en/stable/config-file/v2.html#requirements-file. This should be more easy once #7289 is merged.

Also, we are planning to do this automatically #7290
