踩坑

网上很多教程上使用you-get -i 'https://www.youtube.com/watch?v=6E-jLv1oHCE'

C:\Users\kljxn>you-get -i 'https://www.youtube.com/watch?v=6E-jLv1oHCE'
you-get: [error] oops, something went wrong.
you-get: don't panic, c'est la vie. please try the following steps:

you-get:         https://github.com/soimort/you-get/issues

后面带上--debug，可以查看报错信息。

400状态码是bad requests的意思。
