Я экспериментирую с NodeJS версией API данных YouTube. Я только что сделал следующее руководство здесь: https://developers.google.com/youtube/v3/quickstart/nodejs. Но с приведенным ниже кодом, как в руководстве, я получаю сообщение об ошибке, в котором говорится, что в моем домашнем каталоге нет папки с именем и именем пользователя.

PS D:\Development\NodeJS_YoutubeBrowser>
Я действительно не вижу папку в моем домашнем каталоге с именем .credential. 1. Так, может кто-нибудь сказать мне, когда это фактически создано? Я проверил с настройкой «Показать скрытые файлы». 2. Я на Windows. Я также вижу, что сама папка может быть неточной: mkdir '\ Users \ Pavan Dittakavi / .credentials /' 3. Я также не смог найти ссылки на youtube- nodejs -quickstart. json где-либо.
Пожалуйста, дайте мне знать, где искать эти файлы.
Спасибо, Паван.
