Google驱动器API扩展未找到错误（Python）

我正在尝试将GoogleDrive和GoogleSheetsAPI与Python结合使用，以访问我设置的测试GoogleSheet。在在线教程之后，当我运行代码时，会出现以下错误：

  File "C:\...\Roaming\Python\Python37\site-packages\cryptography\x509\extensions.py", line 131, in get_extension_for_class
    "No {} extension was found".format(extclass), extclass.oid

ExtensionNotFound: No <class 'cryptography.x509.extensions.SubjectAlternativeName'> extension was found

到目前为止我所尝试的：

#import library
import gspread

#Service client credential from oauth2client
from oauth2client.service_account import ServiceAccountCredentials

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

#create some credential using that scope and content of startup_funding.json
creds = ServiceAccountCredentials.from_json_keyfile_name('client_secret.json',scope)
#create gspread authorize using that credential
client = gspread.authorize(creds)

wks = client.open('api_tester').sheet1

• 使用pip安装加密软件包，但它说一切都在那里
• 删除

  .sheet1

  ，这样可以消除错误，但显然不能帮助我实现目标

可能是

.sheet1

方法中的某些东西导致了这种情况吗

我使用的是Python3.7，我有正确的工作表标题，而且据我所知，我对API凭据拥有所有正确的权限（我还为JSON文件中的client_电子邮件授予了工作表编辑权限）

我以前从未见过这样的错误，非常感谢您提供的任何帮助

您安装了哪些版本的Python？可能有解释器混淆。@th0nk-刚刚用cmd行检查过，我正在运行3.7.3。我正在使用Spyder，它在工具栏上方显示“（Python3.7）”。我一直在运行其他Python程序（有些程序调用其他非Google API），但没有问题。你能显示完整的回溯吗？@th0nk-用完整的回溯更新了这个问题。为了便于使用，我建议使用POYMER或pipenv，但在虚拟环境中运行该程序，这样你就可以确保所有源都是最新的。
