【问题描述】：

今天我尝试使用 yahoo-finance 库而不是代码出现一些问题。我提供代码并发生错误。这是图书馆链接https://pypi.org/project/yahoo-finance/

代码：-

from yahoo_finance import Share
yahoo = Share('YHOO')
print(yahoo.get_open())

错误是

Traceback (most recent call last):
  File "/usr/lib/python3.6/urllib/request.py", line 1318, in do_open
    encode_chunked=req.has_header('Transfer-encoding'))
  File "/usr/lib/python3.6/http/client.py", line 1254, in request
    self._send_request(method, url, body, headers, encode_chunked)
  File "/usr/lib/python3.6/http/client.py", line 1300, in _send_request
    self.endheaders(body, encode_chunked=encode_chunked)
  File "/usr/lib/python3.6/http/client.py", line 1249, in endheaders
    self._send_output(message_body, encode_chunked=encode_chunked)

    self.send(msg)
  File "/usr/lib/python3.6/http/client.py", line 974, in send
    self.connect()
  File "/usr/lib/python3.6/http/client.py", line 1407, in connect
    super().connect()
  File "/usr/lib/python3.6/http/client.py", line 946, in connect

    for res in _socket.getaddrinfo(host, port, family, type, proto, flags):
socket.gaierror: [Errno -2] Name or service not known

During handling of the above exception, another exception occurred:

    raise URLError(err)

我不知道这个错误，请帮我解决这个问题。谢谢……

【问题讨论】：

该错误表明python无法解析进行API调用的服务的DNS地址。这可能是您的系统或服务本身的问题。
看起来这个库已经死了，this github issue 指向后端不再运行......猜你需要寻找替代方案：/
你可以试试yahooquery。似乎正在积极维护并提供类似的功能。

包裹坏了。例如，请参阅 GitHub 上的此问题：https://github.com/lukaszbanasiak/yahoo-finance/issues/148

最好的办法是在 GitHub 上指出该包不起作用，也许作者可以进一步帮助您。
