Fermipy installation

[fcasabur]

Hello, I'm trying to install fermipy on my laptop (windows 11 )
According to https://fermipy.readthedocs.io/en/latest/install.html I installed miniforge then I run the Miniforge prompt but

1. If I try
   C:\fermipy>mamba create --name fermipy -c conda-forge -c fermi python=3.9 "fermitools>=2.2.0" healpy gammapy

I get the error

_Looking for: ['python=3.9', "fermitools[version='>=2.2.0']", 'healpy', 'gammapy']

error libmamba Could not open lockfile 'C:\ProgramData\miniforge3\pkgs\cache\cache.lock'_

2. If I try the installation from source

(base) C:\fermipy>git clone https://github.com/fermiPy/fermipy.git

when I try to install I get same error

_base) C:\fermipy>mamba create --name fermipy -f environment.yml

Looking for: ['environment.yml']

error libmamba Could not open lockfile 'C:\ProgramData\miniforge3\pkgs\cache\cache.lock'_

I even tried to clean lock files
mamba clean --locks
