Hey friends, is it possible to export a new virtualenv with just a subset of dependencies from a lockfile?

Also, is it possible to use `-r requirements.txt` inside another `requirements.txt` file to combine subset of requirements using pants? I tried, but differently from what happens using pip, it only installed dependencies from the "child" `requirements.txt` file and it ignored everything that should be imported from the "root" file.

Just a quick reply, so other people can check it in the future:

YES, you can create resolves based on other resolves. I was being dumb because I got confused by the `python_requirements` and `python_requirement` docs, hehe.

If you have a small set of dependencies and want to build a few resolves with some additions and create venvs from them, just this doc: <https://www.pantsbuild.org/docs/reference-python_requirement>

You can set a target as a dependency and add your new dependencies to create a new resolve. It's pretty cool! :slightly_smiling_face:

also, if you want to leverage multiple `requirements.txt` files, you can simply have multiple `python_requirements` targets (one for each file) using the same `resolve` for them.
