i have been using brunch more 1 year in application, yesterday has been observed has stopped functioning. getting error in return attempt run command "brunch watch"

no command 'brunch' found, did mean:  command 'crunch' package 'crunch' (universe)  command 'branch' package 'rheolef' (universe) brunch: command not found

so, tried install brunch again command sudo npm install -g brunch resulted in error:
