使用的命令：
youtube-dl --max-filesize 30m -f m4a -o "/home/dc3014b3c6a1a23bba88b2a1fbcc1447.m4a" "https://www.youtube.com/watch?v=_Xa0ydtx8PM"
youtube-dl对我来说根本无法工作。发生这样的错误：
ERROR: Unable to download webpage: <urlopen error EOF occurred in violation of protocol (_ssl.c:618)> (caused by URLError(SSLEOFError(8, u'EOF occurred in violation of protocol (_ssl.c:618)'),))
OR
ERROR: Unable to download webpage: HTTP Error 429: Too Many Requests (caused by HTTPError()); please report this issue on https://yt-dl.org/bug . Make sure you are using the latest version; type youtube-dl -U to update. Be sure to call youtube-dl with the --verbose flag and include its complete output.
但是当我使用curl命令获取URL内容时，就可以了。
curl -v https://www.youtube.com/watch?v=_Xa0ydtx8PM
我该如何解决？
有效，请尝试将youtube-dl降级。
