python - MacOS 高 OSierra 10.13.6，Python3.7，GeocoderServiceError : [SSL: CERTIFICATE_VERIFY_FAILED]

Question

我最近在 macOS High OSierra 上安装了 python 3.7，并花了很长时间试图让它工作。那个问题是here .目前我在使用以下代码时遇到问题，想知道是否有人可以提供帮助。

import geopy
geocoder = geopy.geocoders.GoogleV3(domain = "maps.google.co.uk")
geocoder.geocode("Cambridge", exactly_one = False)

导致以下错误:
