why I get error-runtime with this python youtubedownloader code

问题

以下是代码的翻译部分：

  1. from pytube import YouTube
  3. # 从用户获取视频链接
  4. link = input("输入要下载的YouTube视频链接: ")
  5. yt = YouTube(link)
  7. # 显示视频详情
  8. print("标题: ", yt.title)
  9. print("观看次数: ", yt.views)
  10. print("视频长度: ", yt.length)
  11. print("视频评分: ", yt.rating)
  13. # 获取最高分辨率的视频流
  14. ys = yt.streams.get_highest_resolution()
  16. # 开始下载
  17. print("下载中...")
  18. ys.download()
  19. 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：
  1. function_patterns = [
  2.     # https://github.com/ytdl-org/youtube-dl/issues/29326#issuecomment-865985377
  3.     # https://github.com/yt-dlp/yt-dlp/commit/48416bc4a8f1d5ff07d5977659cb8ece7640dcd8
  4.     # var Bpa = [iha];
  5.     # ...
  6.     # a.C && (b = a.get("n")) && (b = Bpa[0](b), a.set("n", b),
  7.     # Bpa.length || iha("")) }};
  8.     # 在上述情况中，`iha`是相关的函数名称
  9.     r'a\.[a-zA-Z]\s*&&\s*\([a-z]\s*=\s*a\.get\("n"\)\)\s*&&.*?\|\|\s*([a-z]+)',
  10.     r'\([a-z]\s*=\s*([a-zA-Z0-9$]+)(\[\d+\])?\([a-z]\)',
  11. ]

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

  1. function_patterns = [
  2.     # https://github.com/ytdl-org/youtube-dl/issues/29326#issuecomment-865985377
  3.     # https://github.com/yt-dlp/yt-dlp/commit/48416bc4a8f1d5ff07d5977659cb8ece7640dcd8
  4.     # var Bpa = [iha];
  5.     # ...
  6.     # a.C && (b = a.get("n")) && (b = Bpa[0](b), a.set("n", b),
  7.     # Bpa.length || iha("")) }};
  8.     # In the above case, `iha` is the relevant function name
  9.     r'a\.[a-zA-Z]\s*&&\s*\([a-z]\s*=\s*a\.get\("n"\)\)\s*&&.*?\|\|\s*([a-z]+)',
  10.     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
