【问题描述】：

我无法让这个脚本工作。我将 DEVELOPER_KEY 替换为从 Google API 创建的 API 密钥。如果有人可以帮助我，我将不胜感激。脚本来自这个页面：https://developers.google.com/youtube/v3/code_samples/python#search_by_keyword

#!/usr/bin/python

from apiclient.discovery import build
from apiclient.errors import HttpError
from oauth2client.tools import argparser


# Set DEVELOPER_KEY to the API key value from the APIs & auth > Registered apps
# tab of
#   https://cloud.google.com/console
# Please ensure that you have enabled the YouTube Data API for your project.
DEVELOPER_KEY = "REPLACE_ME"
YOUTUBE_API_SERVICE_NAME = "youtube"
YOUTUBE_API_VERSION = "v3"

youtube = build(YOUTUBE_API_SERVICE_NAME, YOUTUBE_API_VERSION, developerKey=DEVELOPER_KEY)

我收到以下错误消息。

【问题讨论】：

你去推荐页面看了吗？您是否设置了适当的环境变量？
是的，但问题是我不想使用 OAuth 2.0 访问 Google API，我只想使用 API 密钥。这个脚本实际上在几周前运行良好。
现在可以使用了，谢谢。我意识到我误解了说明。
@alicankargin ，我面临同样的问题。该脚本在几周前运行良好。你是怎么解决的。你能发布你的解决方案并接受它作为答案吗

【解决方案1】：

如果您想使用 google-api-python-client 1.6 版，请执行以下操作。转到https://console.developers.google.com/apis/credentials。选择创建凭据，选择服务帐户密钥，选择 App Engine 默认服务帐户，下载 JSON 文件并将其放入您的项目文件夹中。然后将它设置为环境变量GOOGLE_APPLICATION_CREDENTIALS。

os.environ["GOOGLE_APPLICATION_CREDENTIALS"] = "./google_application_credentials.json"

【解决方案2】：

这是 1.6 版 google-api-python-client 的问题。使用以前的版本（1.5.5）应该可以解决问题。
