Add "install-reqs" command to CLI
This extends the CLI, and provides a command wrapper for an additional public function, install_requirements(). This will skip installing the user's code, but will still install all required dependencies. This is particularly useful for preparing building images or containers by enabling users to pre-install dependencies, without installing the source code directly.
This enables installation of dependencies without the need for separate requirements.txt files
flit install-reqs
The following command can be used instead of pip install -r requirements.test.txt or pip install .[test]
flit install-reqs --deps test
Open Issues The following issues are present, because they are required for normal package installation, but are unnecessarily when installing the dependencies.
- User is required to have "README.md"
- User is required to have package directory
I have been working with @brettcannon on a template for Python Projects using pyproject.toml. When converting, I removed my requirements.txt and requirements.test.txt, which would previously be parsed in my setup.py. This leaves me a bit stuck on how to install just my dependencies. Before I went and created some crazy TOML parser, i discovered all the needed code was already located in a public method within 'flit', but had not been exposed.
Hi, sorry it's taken me so long to look at this - life has been getting in the way. :slightly_smiling_face:
I'm happy with the idea of exposing this, but I think I'd prefer to do so as an option for flit install rather than a separate subcommand. How about --only-deps, to mirror pip's --no-deps option?
Poetry has the same thing as --no-root, which I understand - your local project is the root of the dependency ~~tree~~ graph it's dealing with - but I don't find it a particularly clear name.
