I ran into this issue, too. I can confirm that running on the fork resolved it for me: bridgetown new btwf --use-sass -a https://github.com/zalom/bulmatown/tree/fix-27-no-method-error

Stack Overflow suggests the issue occurs starting with ruby 3.2: https://stackoverflow.com/questions/14351272/undefined-method-exists-for-fileclass-nomethoderror
