Hello Sara,

Did you follow all the instructions on the “Environment Setup” page to install the aA dotfiles? The installation process there should get your system set up with all necessary permissions so that you can avoid errors such as these. It might be worth it to look over those instructions and make sure you followed each step. If after you’ve followed the environment setup instructions you are still getting this error, please let us know.
