首先，我对 Ubuntu 还很陌生，我使用它才 20 个小时
from yahoo_finance import Share
yahoo = Share('YHOO')
但每当我运行它时终端都会显示：

我尝试寻找可以修复此问题的方法，但一无所获。

我遇到了同样的错误。我阅读了代码并在以下文件中找到了罪魁祸首（损坏的 URL）：
https://github.com/lukaszbanasiak/yahoo-finance/blob/master/yahoo_finance/yql.py
不幸的是，雅虎似乎停止了这项服务。由于雅虎停止了其 API，雅虎金融 Python 包已损坏。您必须找到另一个包……这是一个潜在的替代方案：https://rapidapi.com/blog/yahoo-finance-api-python/
