- html - 出于某种原因,IE8 对我的 Sass 文件中继承的 html5 CSS 不友好?

我昨天开始自学Python,因此对任何礼节错误都提前致歉。我的挑战是获取一个.csv歌曲名称列表,在YouTube上搜索每个视频,然后使用youtube-dl下载音频。我的代码似乎可以用于一个输出文件,但是由于我无法解决的原因,循环结束了。主要错误是DownloadError: [0;31mERROR:[0m ffprobe or avprobe not found. Please install one.
,但据我所知,我已经安装了它们。我已经尝试并尝试解决此问题,但是没有任何基础知识,我淹没了。我正在使用python 2.7.13。有什么建议吗?抱歉,代码丑陋!

最佳答案
您希望音频为mp3。 YouTube仅提供其他格式的音频,例如m4a。因此,youtube-dl下载m4a文件并将其转换为mp3。 youtube-dl不包含自定义mp3转换器。它使用ffmpeg或avconv进行音频转换。
因此,如果要转换音频,则需要安装ffmpeg或avconv。如何在macOS上is documented in detail at our sister site superuser。
您收到的其他警告是由于Beautifulsoup配置错误。与其尝试自己解析搜索结果,不如让youtube-dl完成,而是使用'ytsearch1:flying bunny'
开头的URL可以解决问题。
