[y/N]:

Could anyone help me solve this problem ? Thanks !

Does it need network connection for activating the mfix-19.1 environment ?

The command
conda env create -n mfix-19.1 mfix/mfix-19.1-win64
requires a network connection; check your connection and try again.

Thanks , that’s it . The problem has been solved.
