python csv罗比尼奥

我正试图使用Python3.6在Windows 10系统上运行此链接中的代码: https://github.com/joshfraser/robinhood-to-csv 但我总是遇到以下错误:

Traceback (most recent call last):
  File "csv-export.py", line 46, in <module>
    logged_in = robinhood.login(username=username, password=password)
  File "C:\Users\rebel\Desktop\Robinhood\robinhood-to-csv-master\Robinhood.py", line 81, in login
    res = res.json()
  File "C:\Users\rebel\AppData\Local\Programs\Python\Python36-32\lib\site-packages\requests\models.py", line 897, in json
    return complexjson.loads(self.text, **kwargs)
  File "C:\Users\rebel\AppData\Local\Programs\Python\Python36-32\lib\json\__init__.py", line 354, in loads
    return _default_decoder.decode(s)
  File "C:\Users\rebel\AppData\Local\Programs\Python\Python36-32\lib\json\decoder.py", line 339, in decode
    obj, end = self.raw_decode(s, idx=_w(s, 0).end())
  File "C:\Users\rebel\AppData\Local\Programs\Python\Python36-32\lib\json\decoder.py", line 357, in raw_decode
    raise JSONDecodeError("Expecting value", s, err.value) from None
json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)

我真的不知道这里会出什么问题。如有任何帮助,我们将不胜感激。谢谢。
