Я пытаюсь создать собственную стратегию загрузки в доморощенном стиле, но тап не работает.
Ошибка ниже отображается после того, как я попытался выполнить команду brew tap ericofusco / test
Я следовал инструкциям от: http://lessthanhero.io/post/homebrew-with-private-repo-releases/.
Кажется, он ожидает, что у меня есть имя класса с именем моего имени файла.
Error: Invalid formula: /usr/local/Homebrew/Library/Taps/ericofusco/homebrew-test/custom_download_strategy.rb
