Unable to install youtube-dl

I tried sudo pip install --upgrade youtube-dl and got back

Requirement already up-to-date: youtube-dl in /Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages

but then youtube-dl --version tells me

-bash: youtube-dl: command not found

I tried without sudo but it still tells me

I can't figure out how to install this. I'm pretty new to python but I've gotten a few other python programs installed with pip and haven't gotten this error before.

Edit: I thought I'd try setuptools, easy_install youtube-dl worked and now youtube-dl --version returns 2016.08.01. I would still like to know why pip wouldn't install it :/

Could you uninstall existing versions with pip uninstall youtube-dl, reinstall it and show installed files via pip show -f youtube-dl?

And, which Mac version are you using? Since El Capitan (10.11), installing youtube-dl globally does not work due to a Mac bug. See #7139 for alternative installation approaches.

I seem to have fixed it? I sudo uninstalled pip and then reinstalled python 2.7 and pip and pip install youtube-dl worked and downloading videos works. It's installed to /Library/Frameworks/Python.framework/Versions/2.7/bin/youtube-dl according to which youtube-dl

Good for you.

FYI for anyone else, if you install Python via Macports you probably want to add something like /opt/local/Library/Frameworks/Python.framework/Versions/2.7/bin to your PATH environment variable.
