That didn’t help but it seems that I homebrew was outdated, so I updated it and fixed all the warnings it caused. The firedrake installation then went a bit further, but still got the following error:

Installing virtualenv.

Dear all,

I tried to update firedrake on my Macbook using the firedrake-install script for the first time, but I got the error below. I can update successfully using the standard steps.

Best, Anna.

Hi Anna,

Does everything work if you do:

brew tap homebrew/science

and then try firedrake-install again.

Lawrence
