为什么从 Yahoo 财务模块下载数据时出现 JSONDecodeError

Question

我是 Python 的新手，我写了一段简单的代码来从 yfinance 模块下载给定股票代码的历史数据。该代码已运行数周，最近，它开始抛出以下异常。这是代码：

data = yf.download("ibm", start="1/1/2017", end="1/6/2021")

这里是错误：

这是一个已知问题，根据 GitHub 存储库的 Issue #777。

，最新版本的 yfinance 模块 (0.1.63) 已修复

将您的 yfinance 模块更新到 0.1.63 或更高版本。
