从雅虎财经下载数据时出现“regularMarketOpen”错误

Question

我正在尝试使用 yfinance 包从 Yahoo Finance 下载数据。我使用下面的代码：

import yfinance as yf
import pandas as pd

fang = ['FB','AMZN','NFLX','GOOG']
tickers = [yf.Ticker(ticker) for ticker in fang]
dfs = [] # list for each ticker's dataframe
for ticker in fang:
    # get each financial statement
    pnl = ticker.financials
    bs = ticker.balancesheet
    cf = ticker.cashflow

    # concatenate into one dataframe
    fs = pd.concat([pnl, bs, cf])

    # make dataframe format nicer
    # Swap dates and columns
    data = fs.T
    # reset index (date) into a column
    data = data.reset_index()
    # Rename old index from '' to Date
    data.columns = ['Date', *data.columns[1:]]
    # Add ticker to dataframe
    data['Ticker'] = ticker.ticker
    dfs.append(data)
data.iloc[:,:3]# for display purposes

但是我有一个错误：

KeyError                                  Traceback (most recent call last)
Input In [5], in <cell line: 8>()
      7 dfs = [] # list for each ticker's dataframe
      8 for ticker in tickers:
      9     # get each financial statement
---> 10     pnl = ticker.financials
     11     bs = ticker.balancesheet
     12     cf = ticker.cashflow
KeyError: 'regularMarketOpen'

我也尝试解决这个问题，如 Yfinance KeyError: 'regularMarketOpen' post 但我没有在 yfinance/base.py

 中找到原始

"data = utils.get_json(url+'/financials', proxy)"
