Почему предварительная компиляция актива capistrano выдает ошибку ci/reporter/rake/rspec?

Развертывание Capistrano выдает следующую ошибку на этапе предварительной компиляции ресурсов.

Я выполнил следующую команду,

шапка промежуточного развертывания

Итак, я попытался запустить ~/.rvm/bin/rvm default do bundle exec rake assets:precompile в папке выпуска, чтобы проверить, не пропустил ли я что-то в своем файле развертывания. Но и там не получилось.

Но когда я запустил ту же команду, ~/.rvm/bin/rvm default do bundle exec rake assets:precompile из моего каталога развертывания (место, из которого я запускаю команду cap deploy), она выполняется успешно.

Ниже приведены настройки среды,
