Support channel prefix in environment.yaml #7202
Description
I'm submitting a...
- bug report
- feature request
It'd be nice if conda env create supported the channel::package syntax in the dependencies list.
Current Behavior
Unclear, but I think that any channels detected as a prefix are pre-pended to the list of channels, and the install proceeds.
Steps to Reproduce
Given this environment.yaml file,
name: test-env
dependencies:
- python=3.6
- flask
- conda-forge::requests
Expected Behavior
I'd expect python and flask to come from the highest priority channel (defaults), and requests to come from conda-forge. It looks like conda-forge was added as the highest priority. I'd further expect that the prefix applies only to requests (and its dependencies?). If I listed another dependency with no channel prefix that's found in conda-forge but not requests, it should error (I think).
