我已成功运行Python2 Google Example Youtube upload code.现在,我想尝试将此代码转换为Python3。当我用2to3工具转换它时,结果如下。如果我尝试用Python3运行它,我会收到如下错误。我使用Rasbian OS。我必须导入哪些Python3库而不是google.oauth2.credentialsgoogle_auth_oauthlib.flowgoogle_auth_oauthlib.flow

转换后的Python3代码:

import argparse
import http.client
import httplib2
import os
import random
import time

import google.oauth2.credentials
import google_auth_oauthlib.flow
from googleapiclient.discovery import build
from googleapiclient.errors import HttpError
from googleapiclient.http import MediaFileUpload
from google_auth_oauthlib.flow import InstalledAppFlow


# Explicitly tell the underlying HTTP transport library not to retry, since
# we are handling retry logic ourselves.
httplib2.RETRIES = 1

# Maximum number of times to retry before giving up.
MAX_RETRIES = 10

# Always retry when these exceptions are raised.
RETRIABLE_EXCEPTIONS = (httplib2.HttpLib2Error, IOError, http.client.NotConnected,
  http.client.IncompleteRead, http.client.ImproperConnectionState,
  http.client.CannotSendRequest, http.client.CannotSendHeader,
  http.client.ResponseNotReady, http.client.BadStatusLine)

# codes is raised.
RETRIABLE_STATUS_CODES = [500, 502, 503, 504]

# The CLIENT_SECRETS_FILE variable specifies the name of a file that contains
# the OAuth 2.0 information for this application, including its client_id and
# client_secret. You can acquire an OAuth 2.0 client ID and client secret from
# the {{ Google Cloud Console }} at
# {{ https://cloud.google.com/console }}.
# Please ensure that you have enabled the YouTube Data API for your project.
# For more information about using OAuth2 to access the YouTube Data API, see:

    #
    # Setting 'chunksize' equal to -1 in the code below means that the entire
    # file will be uploaded in a single HTTP request. (If the upload fails,

    # practice, but if you're using Python older than 2.6 or if you're

看起来您的程序返回了ImportError!这通常发生在您没有从Python下载模块时。执行此操作的方法是在安装pip后运行pip install [module]。对于您的情况,在安装pip run pip install google之后找不到模块google

希望我帮助你解决这个问题。祝你有个美好的一天!
