pytube.exceptions.RegexMatchError Issue

유투브에서 영상이나 음악을 받을 수 있는 Python 패키지중 오픈소스인 pytube가 있다. 손쉽게 Video 또는 Playlist를 다운받을 수 있는데, 최근, 아래와 같은 에러가 발생해서 구글링을 통해 이슈를 해결했다.

    raise RegexMatchError(
pytube.exceptions.RegexMatchError: __init__: could not find match for ^\w+\W

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/Users/jieunchon/opt/anaconda3/lib/python3.8/site-packages/pytube/__main__.py", line 292, in streams

    raise RegexMatchError(
pytube.exceptions.RegexMatchError: __init__: could not find match for ^\w+\W

cipher.py라는 파일에서 일어나는 이슈였다. Regex때문에 발생하는것으로 보였다.

 

여러가지 방법이 있었고, 버전을 낮춰라, 다시 설치해라등의 조언이 있었는데, 해결되지 않았고, 내 경우에는 ciper.py 파일을 수정해주는 것으로 해결했다. (source)

맥을 사용하고있는데, 아래 경로로 가면 pytube 가 있는 위치로 갈 수 있다. 

> cd ~/opt/anaconda3/lib/python3.8/site-packages/pytube

윈도우는 아래 위치라고 한다.

C:\Users<Your Username>\AppData\Local\Programs\Python\Python38\Lib\site-packages\pytube

 

해법은 간단하다. 라인 30번째에 가서 (vim 을 이용했는데, 어떤 에디터를 쓰던지 상관 없다) 아래와 같이 고쳐주었다. (해법 github)

# Before:
var_regex = re.compile(r"^\w+\W")

# After:
var_regex = re.compile(r"^\$*\w+\W")

 

 

수정후에 다시 시도해보자
