问题

I am getting the following error in colab notebook while trying to use pytube for downloading youtube video as mp3 file. I cannot find any solution that works for Colab. Please help me out.

RegexMatchError: __init__: could not find match for ^\w+\W

Here is my code:

for url in url_list:
  print(url)
  # try:
  yt = YouTube(url)
  title = yt.title
  print("processing " + title)
  if os.path.exists(os.path.join(destination, title + ".mp3")):
      print("file exists")
      continue  
  video = yt.streams.filter(only_audio=True).first()
  print(video)    
  out_file = video.download(output_path=destination)
  base, ext = os.path.splitext(out_file)
  new_file = base + '.mp3'
  os.rename(out_file, new_file)

I solved the above issue in the following manner.

1. 我以以下方式解决了上述问题。
2. Then in a new branch, I made the following edits to cipher.py file of pytube package - In line 30, I replaced var_regex = re.compile(r"^\w+\W") with var_regex = re.compile(r"^\$*\w+\W")
3. 然后在一个新分支中，我对pytube包的cipher.py文件进行了以下编辑 - 在第30行，我将var_regex = re.compile(r"^\w+\W")替换为var_regex = re.compile(r"^\$*\w+\W")
4. Finally installed the package in colab from my github branch
5. 最后，从我的GitHub分支在Colab中安装了该包

!pip install pytube@git+https://github.com/priyankaj1311/pytube.git@master_copy
