安装使用
To install it right away for all UNIX users (Linux, OS X, etc.), type:

sudo curl -L https://yt-dl.org/downloads/latest/youtube-dl -o /usr/local/bin/youtube-dl

sudo chmod a+rx /usr/local/bin/youtube-dl

windows.exe地址
https://yt-dl.org/downloads/2021.12.17/youtube-dl.exe

Windows users can download an .exe file and place it in any location on their PATH except for %SYSTEMROOT%System32 (e.g. do not put in C:WindowsSystem32).

If you do not have curl, you can alternatively use a recent wget:

sudo wget https://yt-dl.org/downloads/latest/youtube-dl -O /usr/local/bin/youtube-dl

sudo chmod a+rx /usr/local/bin/youtube-dl

You can also use pip:

sudo pip install --upgrade youtube_dl

sudo wget https://yt-dl.org/downloads/latest/youtube-dl.sig -O youtube-dl.sig
gpg --verify youtube-dl.sig /usr/local/bin/youtube-dl

youtube-dl 下载需要登录的资源

安装GetCookie插件（https://chrome.google.com/webstore/detail/get-cookiestxt/bgaddhkoddajcdgocldbbfleckgcbcid）

I then visited YouTube.com, while I was logged in, and clicked on the Get
Cookies icon. Then I clicked on the “Export” button to download my YouTube cookies as a text file.

This created a youtube.com_cookies.txt file that I then copied into the YouTube-DL directory on my laptop.
Finally I ran the following command in YouTube-DL to pass the cookie to YouTube and download the video:

youtube-dl -f bestvideo+bestaudio --merge-output-format mkv --all-subs --cookies youtube.com_cookies.txt [YouTube URL]

使用 youtube-dl 只下载音频
如果你只想从 YouTube 视频中下载音频，你可以使用 youtube-dl 的 -x 选项。这个提取音频的选项将视频文件转换为纯音频文件。

youtube-dl -x video_URL

该文件被保存在你运行 youtube-dl 命令的同一目录下。

如你想提取 MP3 格式的音频。你可以像这样使用它：

youtube-dl -x --audio-format mp3 video_URL
