In order to install the module dolfin for Python one has to install Fenics. I'm working with Anaconda on Windows.
I tried to install Fenics writing on the Anaconda Prompt : conda create -n fenicsproject -c conda-forge fenics
And this error appears :
All I see is a spelling mistake and using cond-forge instead of conda-forge. But other than that fenics is only available for Mac and Linux versions of Anaconda. So perhaps you should use Docker.
