Error when using animation.py on Julia 1.5.2

Question

I use the first example of this link to make a videos. On my previous Julia version before I changed computer, which was I think version 1.2, this worked fine. Now, everything works fine, until the last line

myanim[:save]("testvid.mp4",writer=mywriter) 

To which I get the error message:

ERROR: PyError ($(Expr(:escape, :(ccall(#= /Users/XX/.julia/packages/PyCall/BcTLp/src/pyfncall.jl:43 =# @pysym(:PyObject_Call), PyPtr, (PyPtr, PyPtr, PyPtr), o, pyargsptr, kw))))) <class 'FileNotFoundError'>

Does anyone know what is going on?

The exact same code ran perfectly in the former Julia version.
