谷歌雲函數在函數視圖日志中導入錯誤

Question

我在 python 運行時環境中創建了一個由谷歌雲 pubsub 觸發的谷歌雲函數，我還添加了需求依賴項，但是當我運行該函數時它工作正常但它記錄了一些導入錯誤所以我該如何解決這個問題。

您可以抑制日志消息：

import logging

logging.getLogger('googleapicliet.discovery_cache').setLevel(logging.ERROR)`

或者在使用discovery.build()時設置cache_discovery=False ：

self.client = discovery.build(
    service_name,
    api_version,
    discoveryServiceUrl=discovery_url,
    credentials=scoped_credentials,
    cache_discovery=False,
)
