python – Cannot create virtual environment with Mamba/Conda

I have tried running

mamba create -n my_env

to which it returns

usage: mamba [-h] [--version] [--slow SLOW] [--enable-coverage] [--coverage-file COVERAGE_FILE] [--format FORMAT] [--no-color]
             [--tags TAGS]
             [specs ...]
mamba: error: unrecognized arguments: -n my_env

I recently deleted all of my anaconda installations and restarted from a fresh miniconda installation. I’m guessing there may be an error in my .bash_profile, but I am unsure what exactly I am looking for in those files.
