Я создал приложение rails и попытался запустить сервер rails. Я получил следующую ошибку:
/home/ritesh/.rvm/gems/ruby-1.9.3-p429/gems/execjs-2.0.1/lib/execjs/runtimes.rb:51:in `autodetect': Could not find a JavaScript runtime. See https://github.com/sstephenson/execjs for a list of available runtimes. (ExecJS::RuntimeUnavailable)

хотя я смог исправить это, удалив комментарий перед строкой gem 'therubyracer', platforms: :ruby из Gemfile.
Почему этот жемчуг прокомментирован, когда мы требуем его на первом месте при запуске приложения rails?
