当我运行 youtube-dl 时,我收到以下消息(很长)。这是什么问题?我该如何解决?它告诉我更新 youtube-dl,但我正在使用 youtube-dl 执行命令在终端中运行它 - 我认为它实际上并未安装在我的 PC 上。

答案1
该youtube-dl
项目已非正式地停止运营。自 6 月以来,该项目一直没有更新,尽管之前非常活跃。项目维护人员没有发布任何回应,而且该项目从几个月前开始在许多网站上出现严重问题。
许多人已经移居到yt-dlp
,它有几个安装选项,包括 PIP。

您必须等待下一个版本。
或者,如果您很着急并且等不及下一个版本,您可以手动编辑安装中的“youtube.py”文件。
在我的安装中,该文件位于:
/usr/local/lib/python3.8/dist-packages/youtube_dl/extractor/youtube.py
我手动进行了替换,然后再次下载。
答案3
我刚刚创建了一个拉取请求来修补它。简而言之,youtube 将其双字符函数更改为三字符函数:它破坏了 youtube-dl 的正则表达式。
如果您将项目拉到本地,则在终端中运行它:
python -m youtube_dl -x --audio-format mp3 https://youtu.be/lhXFIz0pVv4
它应该下载到项目文件夹中。
