what if you only need the lockfile? Would you need create to a temporary environment first just to delete it later? Fortunately, there's a way: you can invoke conda in JSON mode and then process the output environment conda create --clone ENVNAME -n NEWENV rename environment conda rename -n ENVNAME NEWENVNAME delete environment by name conda remove -n ENVNAME --all list revisions made to environment conda list Arguments --all Remove all packages, i.e., the entire environment. --keep-env Used with --all, delete all packages but keep the environment. --dev Use sys.executable -m conda in wrapper scripts instead
