使用pytube下载youtube视频时出现属性错误

问题描述

我已经使用Python一段时间了，我决定使用pytube从Youtube下载视频，但是当我尝试下载视频时，出现属性错误。

import pytube
from pytube import *


def run():
try:
    down_dir = "C:/Users/ASUS/Desktop/python projects/youtube_video_installer"
    video_link = input("enter video url")
    res_selected = input("enter required res")
    youtube = YouTube(video_link)
    title = youtube.title
    print("Now downloading," + str(title))

    video = youtube.streams.get_by_resolution(res_selected)
    # file_size = "FileSize : " + str(round(video.filesize / (1024 * 1024))) + "MB"

    print(title)

    if down_dir is not None:
        video.download(output_path=down_dir,filename=str(title))
    else:
        video.download()
    print("Download complete," + str(title))

except Exception as e:
    print("ErrorDownloadVideo  |  " + str(video_link))


run()

当我设置视频= youtube.streams.first（）时 它可以工作，但是每当我使用.get_by_itag或.get_by_resolution指定视频时，都会出现此错误

   File "C:/Users/ASUS/Desktop/python projects/youtube_video_installer/console.py",line 31,in          <module>
     run()
   File "C:/Users/ASUS/Desktop/python projects/youtube_video_installer/console.py",line 22,in run
     video.download(output_path=down_dir,filename=str(title))
   AttributeError: 'NoneType' object has no attribute 'download'
