python - 模块未找到错误 : No module named 'google.appengine'

Question

我想在 Windows 上用 python3 进行谷歌搜索。谷歌说明说他们支持 python3 并键入“gcloud topic init”以获取详细信息 - 但没有说 python2.7 没有解释器。我是否必须安装 python2.7 才能了解如何让它在 python3 上运行？

在 python3 上，我收到如下错误消息。我已经设置了一个 API key 和一个自定义搜索引擎。我做了“pip install google-api-python-client”。我下载并运行了 GoogleCloudSDKInstaller。这是错误:

from googleapiclient.discovery import build
service = build("customsearch", "v1", developerKey="xxxxxx")

我得到:

创建服务时需要参数cache_discovery=False，如下:

service = discovery.build('customsearch', 'v1', credentials=<...>, cache_discovery=False)
