is `conda install` used for installing dependencies if a Conda environment is activated?

• I have searched the issues of this repo and believe that this is not a duplicate.

Issue

As of 1.0.0 Conda environments are supported. When I install the dependencies of a project with poetry install, and say numpy is in the dependencies, will it use the numpy I get with conda install numpy or the numpy I get with pip install numpy?

@finswimmer Is there any progress/plan in supporting packages from conda channels in addition to pypi?

Conda is great for creating isolated python environments on Windows. On the other hand, in my experience, the tech behind conda packages is great in principle, but fails in practice. I used to install packages mainly from conda repositories, and pip for whatever wasn’t available, but updating mixed environments was a big headache. Mixing the two complicates things greatly. There are serious discrepancies between conda repositories and pypi: the same module is sometimes packaged with different names, dependencies can be different for the same module, and conda tends to lag behind making new versions available. Also, Pypi is simply better known and supported. I can imagine that it would be a very complex task for poetry developers to make the two systems work together; perhaps not a good idea altogether.
