Description of your issue, suggested solution and other information

I just freshly installed homebrew by issuing

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

and then installed youtube dl

brew install youtube-dl

running youtube-dl -v https://www.youtube.com/watch?v=Js3WIRF595U

it gave me the CERTIFICATE_VERIFY_FAILED error, so I did brew uninstall youtube-dl an tried installing it via curl

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

Same thing, I found 2 other closed issues related to reinstalling SSL, I tried that, but it still doesnt work.

$ openssl version
OpenSSL 1.0.2k  26 Jan 2017

I'm running macOS Sierra 10.12

This is not a standard Homebrew Python path. Could you check if you have other package managers installed? (MacPorts, Fink, ...)

I can reproduce the certificate verification failure issue on Windows 10 (youtube-dl installed through Chocolatey)

@milleniumbug: How SSL works on Windows is different. Check #7309 (comment)

As there are no more responses from the original poster, I'm closing this issue.

[jschwalbe]

@yan12125 Can I reopen it? I'm still having a similar problem (if not the same). macOS, installed via pip3.

@jschwalbe: Most likely you are bitten by a Mac issue. Check out #11943 (comment)

[jschwalbe]

Thanks @yan12125.
Since SSL isn't important to me, I've just updated my script to use the workaround:
--no-check-certificate Suppress HTTPS certificate validation

[ezerbib]

For me it was the date of the device which was set later than the certificate expiration date. So double check the date of the device you run youtube-dl

[dezza]

Make sure you have
pip install certifi
Installs Mozilla CA-bundle, apparently it's not included with Python3 installations. But it fixed a similar issue for me.
