gspread加注ResponseNotReady

Question

当我尝试使用gspread访问谷歌电子表格时，它总是返回“提升ResponseNotReady（）”，我只是按照Github中的用户指南，我不熟悉httplib和gspread，有人可以告诉我如何做对了，谢谢你的帮助

源代码：

import gspread
from oauth2client.service_account import ServiceAccountCredentials

scope = ['https://spreadsheets.google.com/feeds',
         'https://www.googleapis.com/auth/drive']

creds = ServiceAccountCredentials.from_json_keyfile_name('Orait-2018-06-09-200299f40c5e.json', scope)
client = gspread.authorize(creds)
wks = gc.open("sheet1").sheet1
