I’m having a dependency issue on the newest version of yt_dlp (see Verbose Output). I tried purging the pip3 cache and uninstalling yt_dlp and it’s dependencies then reinstalling:

Error remains. Reverting to yt_dlp 2023.01.06 makes error go away.

Provide verbose output that clearly demonstrates the problem

I am also getting this issue, but only when using pyinstaller. Installing cffi does not do anything.

My issue is resolved as well now. As I was starting to gather the information that @pukkandan asked for, it looks like the following two commands completely fixed my problem (use pip to downgrade yt-dlp to 2023.1.6, and then upgrade it back to 2023.02.17): pip install yt-dlp==2023.1.6 pip install yt-dlp==2023.02.17

This seemed to properly install yt-dlp together will all needed dependencies, including pycryptodomex and mutagen.

The way I was using yt-dlp previously was not through pip, but from the release binaries. And then I was running yt-dlp -U to keep upgrading it to the latest version. I guess at some point something went wrong and then this issue showed up. But now, reinstalling yt-dlp through pip has resolved the issue.

In the end I did not have to resort to using @pukkandan’s diff solution workaround.

"Me too"s without additional details isn’t helping anyone. I have yet to be able to reproduce the issue.

If you are having the issue, run the following and post their outputs:

yt-dlp -v ~~on both the new and old versions (use pip install yt-dlp==2023.1.6 to install old version)~~
If on PIP (change py to python/python3 if needed):
- py -c "from Cryptodome.Cipher import AES; print(AES)"
- py -c "from Crypto.Cipher import AES; print(AES)"
- pip install cffi
- Repeat the first 2
- (pip freeze may also help)
If compiled yourself (pyinstaller etc)
- Everything from PIP section
- Post exact steps of how you compiled it

My guess is that cryptodome install is somehow broken in your systems and previous versions of yt-dlp were silently ignoring the error[^1]. If I am right, it’s an easy fix to make yt-dlp ignore the error again. But first I need to be sure

If you can, also test if this works around the problem

Does pip install cffi fix the issue?

pukkandan on Feb 17, 2023

I tried downgrading and then upgrading, doing the fix here. this runs fine locally, but when i deploy it to AWS lambda now it fails with the following error. Any suggestions?
