Я хочу протестировать с Selenium, но я получаю сообщение об ошибке Webdrivers :: BrowserNotFound

В настоящее время я пишу тесты с использованием Rails5, Rspec, Selenium и webdrivers gems.
Однако я получаю сообщение об ошибке Webdrivers :: BrowserNotFound и не могу его запустить.

Я думаю, что это связано сСелену не удалось найти ChromeDriver.
Тем не менее, эта проблема должна была быть решена с помощью гема webdrivers, но, похоже, он не работает должным образом.
Подробности будут написаны ниже.

Я также включил ведение журнала отладки Webdrivers. Вот журнал в то время.

Решено.
Это потому, что не был установлен Google Chrome.
Извините.
