Was this for an existing install (thus the -U)? Can you try with pip via sudo pip install --upgrade streamlink? I've run into weird issues like this with easy install before but using pip solves it.

Hey thanks for your answer,
I'm a total noob with the terminal / python. Is pip a tool i need to install ? I tried but "command not fund"

Edit : Installed pip and worked =D thanks a lot !

@Romain1999 Awesome glad to hear it! I'm going to close this out for now since you're all set.
