python - python文件显示AttributeError：模块'http'没有属性'client'

Question

我有以下 Python 脚本：

import http
import requests
from bs4 import BeautifulSoup
import urllib3
import pyrebase
import numpy as np
import yagmail
import time
from datetime import datetime, timedelta
import sys
import logging
import colorama
import csv
from random import randint
from numpy import genfromtxt
import sched, time
import threading
import http.client

import firebase_admin
from firebase_admin import credentials
from firebase_admin import db


# Fetch the service account key JSON file contents
cred = credentials.Certificate('service-account-credentials.json')
# Initialize the app with a service account, granting admin privileges
firebase_admin.initialize_app(cred, {
    'databaseURL': 'https://werrwrrw-catalogue.firebaseio.com'
})


config = {
    "apiKey": "BiXzaSdwhjwrhwjjrhwr",
    "authDomain": "whjwrhwjjrhwr.firebaseapp.com",
    "databaseURL": "https://whjwrhwjjrhwr.firebaseio.com",
    "projectId": "whjwrhwjjrhwr",
    "storageBucket": "rewrrrrr.appspot.com",
    "messagingSenderId": "606543434441"
}



firebaseuser = pyrebase.initialize_app(config)

auth = firebaseuser.auth()
dbuser = firebaseuser.database()

subref = db.reference('Subcribers').get()

for key, val in subref.items():
    subcriber_email = val['Email']
    print(key,subcriber_email)

python 文件之前运行良好，但现在当我尝试运行它时，它显示以下错误：

我无法确定错误。如何根据上面的回溯阅读修复错误？

Answer 1

这里：

File "/Users/name/anaconda/lib/python3.6/http/client.py", line 71, in <module>
    import email.parser
File "/Users/name/Desktop/Google Drive/FEBB/serverless/crwlr/email.py"
    from bs4 import BeautifulSoup

email.py/Users/name/Desktop/Google Drive/FEBB/serverless/crwlr/ 中的本地会影响 stdlib 的本地化。现在在您的本地 email.py 模块中，您正在导入 bs4，它会导入 html5lib，它会导入 xml.sax.saxutils，它会导入 urllib.request，它要导入http.

IOW 你最终会得到一个（意外的）循环依赖。此时，http 模块仅部分导入，尚未定义“客户端”，因此出现错误。

简单的解决方案是将您的“email.py”模块重命名为其他名称，或者（如果它只是一个脚本而不是模块）将它移出您的 pythonpath。

编辑：我刚刚注意到你的代码是从 importing 开始的http，所以 http 模块应该已经完全加载，所以即使你的email.py脚本/模块的问题需要修复，这也不应该导致这个问题。因此，您可能有另一个http.py模块或http包在您sys.path的 stdlib 的影子中。要对此进行调试，请在这一行之后添加这一行import http：

 print(http)

这应该打印如下内容：

<module 'http' from '/some/path/to/a/python/file.pyc`>

如果路径不是您的 python 安装 stdlib 的“http/ init .pyc”的路径，那么您找到了违规者。如果它是您自己的脚本/模块之一，则修复与 for 相同email.py。
