now PyEnvironment only accepts conda packages. pypi packages should also be supported.

see https://github.com/conda/rattler/blob/main/py-rattler/src/lock/mod.rs#L149

Indeed! Would you be able to open a Pr?

@baszalmstra sorry, i'm not familiar with the python api and python binds.

ps, the PyEnvironment seems also lack the api for pypi indexes.

could this be somewhat related to #1044 ?

[baszalmstra]

That totally depends on the API we want here. We can also modify the constructor to accept LockedPackage and allow constructing those types from python as well.
