why I get error-runtime with this python youtubedownloader code

问题

以下是代码的翻译部分：

from pytube import YouTube

# 从用户获取视频链接
link = input("输入要下载的YouTube视频链接: ")
yt = YouTube(link)

# 显示视频详情
print("标题: ", yt.title)
print("观看次数: ", yt.views)
print("视频长度: ", yt.length)
print("视频评分: ", yt.rating)

# 获取最高分辨率的视频流
ys = yt.streams.get_highest_resolution()

# 开始下载
print("下载中...")
ys.download()
print("下载完成!!")

请注意，你的错误似乎与YouTube的一些更改或限制有关，可能需要检查你的网络连接或确保你的代码库（pytube）是最新的。此外，你的代码中存在一些HTML实体字符（"），你可以将它们替换为普通的引号字符（"）以避免问题。

这是我的代码来下载视频或播放列表：

from pytube import YouTube, Playlist

# 下载单个视频的函数
def download_video(url):
    try:
        yt = YouTube(url)
        stream = yt.streams.get_highest_resolution()
        print(f"下载视频: {yt.title}")
        stream.download()
        print("下载完成！")
    except Exception as e:
        print(f"错误: {str(e)}")

# 下载播放列表的函数
def download_playlist(url):
    try:
        playlist = Playlist(url)
        print(f"播放列表中的总视频数: {len(playlist.video_urls)}")
        for video_url in playlist.video_urls:
            download_video(video_url)
    except Exception as e:
        print(f"错误: {str(e)}")

# 主程序
user_input = input("输入 YouTube 视频 URL 或播放列表 URL: ")
if "youtube.com/playlist" in user_input:

这似乎是pytube中的一个BUG。在存储库中已经提出了一个问题（RegexMatchError: get_throttling_function_name: 无法找到多个#1707的匹配项1）。查看这个评论以获取一种解决方法。

英文:

This seems to be a BUG in pytube. A issue has already raised RegexMatchError: get_throttling_function_name: could not find match for multiple #1707) in the repository. See this comment for a workaround soultion.

解决方案：

  1. 前往pytube库（使用pip show pytube查找位置）
  2. 更改cipher.py -> get_throttling_function_name -> function_patterns为以下内容：
function_patterns = [
    # https://github.com/ytdl-org/youtube-dl/issues/29326#issuecomment-865985377
    # https://github.com/yt-dlp/yt-dlp/commit/48416bc4a8f1d5ff07d5977659cb8ece7640dcd8
    # var Bpa = [iha];
    # ...
    # a.C && (b = a.get("n")) && (b = Bpa[0](b), a.set("n", b),
    # Bpa.length || iha("")) }};
    # 在上述情况中，`iha`是相关的函数名称
    r'a\.[a-zA-Z]\s*&&\s*\([a-z]\s*=\s*a\.get\("n"\)\)\s*&&.*?\|\|\s*([a-z]+)',
    r'\([a-z]\s*=\s*([a-zA-Z0-9$]+)(\[\d+\])?\([a-z]\)',
]

在我的情况下，这是第264行
4. 运行py脚本
这对我有用

英文:

Solution:

  1. go to the pytube library (you find the location using pip show pytube )
    为什么我在使用这个Python的YouTube下载器代码时会收到运行时错误？

  2. change cipher.py -> get_throttling_function_name -> function_patterns to

function_patterns = [
    # https://github.com/ytdl-org/youtube-dl/issues/29326#issuecomment-865985377
    # https://github.com/yt-dlp/yt-dlp/commit/48416bc4a8f1d5ff07d5977659cb8ece7640dcd8
    # var Bpa = [iha];
    # ...
    # a.C && (b = a.get("n")) && (b = Bpa[0](b), a.set("n", b),
    # Bpa.length || iha("")) }};
    # In the above case, `iha` is the relevant function name
    r'a\.[a-zA-Z]\s*&&\s*\([a-z]\s*=\s*a\.get\("n"\)\)\s*&&.*?\|\|\s*([a-z]+)',
    r'\([a-z]\s*=\s*([a-zA-Z0-9$]+)(\[\d+\])?\([a-z]\)', ]

in my case it is 264 line
为什么我在使用这个Python的YouTube下载器代码时会收到运行时错误？
4. run the py script<br/>
this worked for me
