python - "TypeError: cannot instantiate ctype ' EVP_MD_CTX ' of unknown size"尝试构建谷歌预测 api

Question

下面是代码

import httplib2, argparse, os, sys, json
from oauth2client import tools, file, client
from oauth2client.service_account import ServiceAccountCredentials
from googleapiclient import discovery
from googleapiclient.errors import HttpError

scope = ['https://www.googleapis.com/auth/prediction','https://www.googleapis.com/auth/devstorage.read_only']

def get_api(api, scope, service_account=True):
     storage = file.Storage('oAuth2.json')
     creds = storage.get()

     if creds is None or creds.invalid:
        creds = ServiceAccountCredentials.from_json_keyfile_name('service_account.json',
                                                             scopes=scope)
        storage.put(creds)

     http = creds.authorize(httplib2.Http())
     return discovery.build(api, 'v1.6', http=http)

api = get_prediction_api('prediction')

错误如下

TypeError: cannot instantiate ctype 'EVP_MD_CTX' of unknown size

基于此blog
