当我运行此代码时，出现错误

到目前为止，这里报告的解决方案都不适合我。根据讨论here雅虎对其 API 进行了更改，破坏了与以前的 pandas datareader 版本的兼容性。
在同一个 Github 线程中报告了一个修复，该修复是在 Github 用户 raphi6 的拉取请求中实现的。我确认拉取请求工作正常。可以使用以下 3 行安装拉取请求中的版本：
conda install pycryptodome pycryptodomex
conda uninstall pandas-datareader
pip install git+https://github.com/raphi6/pandas-datareader.git@ea66d6b981554f9d0262038aef2106dda7138316
pycrypto*Yahoo!_Issue#952这也可以使用 pip 代替 conda 来完成所有命令（请参阅下面的更新 1）。
更新1
要在 Google Colab 上尝试此操作（如此处所示）：
! pip install pycryptodome pycryptodomex
! pip uninstall --yes pandas-datareader
! pip install git+https://github.com/raphi6/pandas-datareader.git@ea66d6b981554f9d0262038aef2106dda7138316
更新2（2022年12月27日）
虽然上周我无法使其工作，但我再次尝试了，并且我可以确认 Nikhil Mulley 下面提到的
pdr_override()原始答案（有效，但代码行更多）
在同一个 Github 线程中报告了一个修复，该修复是在 Github 用户 raphi6 的拉取请求中实现的。我确认拉取请求工作正常。拉取请求的详细安装说明可以在here找到，为了完整起见，复制如下：
git clone https://github.com/raphi6/pandas-datareader.git
cd pandas-datareader
conda uninstall pandas-datareader
conda install pycryptodome pycryptodomex
git checkout 'Yahoo!_Issue#952'
python setup.py install --record installed_files.txt
安装命令中的
--recordpycrypto*这不是答案，但我认为问题与从雅虎本身获取的 pdr 数据读取器有关

和短期修复可能是使用 yfinance 覆盖，看看这是否有帮助，直到雅虎财经恢复其数据功能？

我的解决方案很简单，我只需将 pandas_datareader.get_data_yahoo 替换为 yf.download 即可。不用担心结果，因为 yf.download 还会给你一个数据框。我将语法简化如下：
import yfinance as yf
df = yf.download(your_ticks_or_a_tick_list, start=start_date, end=end_date)
但是请记住清除所有单元格的输出，然后重新启动，否则会出现错误。
改用雅虎财经，它对我有用：
import datetime as dt
import yfinance as yf
company = 'TATAELXSI.NS'
# Define a start date and End Date
start = dt.datetime(2020,1,1)
end = dt.datetime(2022,1,1)
# Read Stock Price Data
data = yf.download(company, start , end)
data.tail(10)
2023 年 9 月 25 日对我有用的解决方案
我替换
import pandas_datareader as web
web.DataReader('AMZN', 'yahoo', start, end)
与
import yfinance
yfinance.download('AMZN', start, end)
更新 yfinance 它对我有用。
