Why does this python code give "TypeError: the JSON object must be str, not 'bytes'" on one machine but not another

Question

我有一个 small public repo 具有以下 python 代码：

#!/usr/bin/python
# -*- coding: utf-8 -*-
import urllib.request, urllib.parse, urllib.error
import json
from urllib.request import urlopen, Request
import os

def get_json_from_url(url):
    config = json.loads(open(os.path.dirname(os.path.abspath(__file__))+'/config.json').read())
    token = config['token']
    request = Request(url)
    request.add_header('Authorization', 'token %s' % token)
    request.add_header('Accept', "application/vnd.github.inertia-preview+json" )
    response = urlopen(request)
    return json.loads(response.read())

def process_cards(pri,url, tag=""):
   cards= get_json_from_url(url)
   for card in cards: 
       payload=""
       if card['note']:
            payload="map project:"+ card['note']
       else:
            payload="Work on: "+ card['content_url']
       print("({}) {} {}".format(pri,payload,tag))


def process_project_board(url,tag=""):
   board= get_json_from_url(url)
   columns_url= board["columns_url"]
   columns= get_json_from_url(columns_url)
   priorities=['*', 'A', 'B', 'C', 'D','E']
   for x in columns:
      process_cards(priorities.pop(0),x['cards_url'],tag)

if __name__ == "__main__":
   process_project_board("https://api.github.com/projects/1613733","+EQT")
   process_project_board("https://api.github.com/projects/1659667","+PersonalProjects")

当我运行使用

时，它在我的桌面上运行完美

python3 vision.py

但是当我在服务器上克隆它时，出现以下错误：

Traceback (most recent call last):
  File "vision.py", line 37, in <module>
    process_project_board("https://api.github.com/projects/1613733","+EQT")
  File "vision.py", line 29, in process_project_board
    board= get_json_from_url(url)
  File "vision.py", line 15, in get_json_from_url
    return json.loads(response.read())
  File "/usr/lib/python3.4/json/__init__.py", line 312, in loads
    s.__class__.__name__))
TypeError: the JSON object must be str, not 'bytes'

导致行为差异的原因是什么？没有丢失库错误 - config.json 文件（我的 Github 令牌所在的位置）是相同的，而且我从未遇到类似的问题将东西移到服务器......

您必须在您的服务器上使用低于 3.6 的 Python 版本，并且 JSON 未按预期运行。升级您的 Python 版本或使用 virualenv，以便您可以在桌面和服务器上使用相同的代码
