difficulty compiling TikZ code - unknown key "breakable" [closed]

Question

In attempting to compile some TikZ related code by Gonzalo Medina, I am running into difficulties. The code is accessible here:

Creation of a new poster template

Specifically, I am encountering the following error:

! Package pgfkeys Error: I do not know the key '/tcb/library/breakable' and I a
m going to ignore it. Perhaps you misspelled it.

See the pgfkeys package documentation for explanation.
Type  H <return>  for immediate help.
 ...                                              

l.13 \tcbuselibrary{skins,theorems,breakable}

?

Could you suggest how I might approach this problem?

EDIT: I have added the code I'm using below:
