【问题描述】:
我正在使用 gspread 将我的应用程序连接到电子表格,为此我使用以下代码
import json
import gspread
from oauth2client.client import SignedJwtAssertionCredentials
json_key = json.load(open('service_account.json'))
scope = ['https://spreadsheets.google.com/feeds']
credentials = SignedJwtAssertionCredentials(json_key['client_email'], json_key['private_key'], scope)
gc = gspread.authorize(credentials)
sheet = gc.open('Order Database').sheet1
当我在空闲时使用它来访问电子表格时,同样的代码运行良好。但是当我在我使用 Google App Engine 的应用程序的代码中使用它时,当我运行应用程序并尝试访问该页面我收到此错误

CryptoUnavailableError: No crypto library available
我什至成功安装了项目目录中的库:
pip install -t lib PyOpenSSL
pip install -t lib gspread
pip install -t lib oauth2client
pip install -t lib cryptography
我什至尝试将--upgrade 添加到每个文件中,并且所有文件都已成功安装,但出现相同的错误
如果我做错了什么,请告诉我,我该如何解决这个问题?
提前致谢。
【问题讨论】:
-
错误是来自本地应用服务器,还是来自生产环境?或两者?从日志中我猜它是本地的
-
如果你做一个测试脚本,你可以手动
import这个库吗? -
@TimCastelijns 我正在使用 google app engine 应用程序在本地运行它......以及通过库你在谈论哪些?
-
找不到的那个,crypto
-
如果你告诉我添加这个:
from OpenSSL import crypto我得到一个ImportError: No module named cryptography.hazmat.bindings._openssl
