1.安装pip
我的服务器上已经有了python3，但是看了下，没有pip3，安装它。
// 下面命令下载get-pip.py
curl -sSL https://bootstrap.pypa.io/get-pip.py -o get-pip.py
// 下面命令安装pip
python3 get-pip.py
安装的时候报错了：
~/python$ python3 get-pip.py
Traceback (most recent call last):
File "get-pip.py", line 27077, in <module>
main()
File "get-pip.py", line 135, in main

ModuleNotFoundError: No module named 'distutils.cmd'
于是，根据错误提示，还需要安装distutils.cmd
sudo apt install python3-distutils
装好后，即可安装。
2.安装you-get
使用下面命令安装：
pip install you-get
安装好后，有下面的警告，添加到环境变量即可。
WARNING: The script you-get is installed in '/home/xxx/.local/bin' which is not on PATH.
添加到环境变量
// 添加到.bashrc中
echo "export PATH=/home/xxx/.local/bin:$PATH" >> ~/.bashrc
// 使.bashrc生效
source ~/.bashrc
3.下载视频
you-get -I https:xxx能看到视频列表。
you-get -i https://www.youtube.com/watch?v=Qq0V09-s6LI
