Похоже эти optionalDependencies почему-то не установились.
Гугл советует попробовать установить их или переустановить imagemin.
gulp-imagemin: Couldn't load default plugin xxx - Stack Overflow
npm install imagemin-mozjpeg imagemin-svgo imagemin-gifsicle imagemin-optipng --save
А зачем этот imagemin понадобился вообще?
Если это просто несколько картинок проекта типа лого и т.д., то лучше сразу самому их в нужном качестве/размере сделать. Тем более что если оно обещает lossless, то наверняка в большинстве случаев (если картинка создана нормальным ПО) оно сожмет максимум на несколько десятков байт. Как в примере в их ридми и есть )
При вставке кода/вывода консоли надо нажимать кнопку Код.
