Easier UVM Scoreboard not working

[Mario Gómez Pozo]

Hi, I am trying to test the easier uvm example with a syosil scoreboard (https://www.edaplayground.com/x/5ps) but when I run the simulation I get the following error:

Error-[SV-LCM-PND] Package not defined
../tb/top/sv/top_env.sv, 21
top_pkg, "pk_syoscb::"
Package scope resolution failed. Token 'pk_syoscb' is not a package.
Originating module 'top_pkg'.
Move package definition before the use of the package.

Error-[SE] Syntax error
Following verilog source has syntax error :
token 'cl_syoscb' should be a valid type. Please declare it virtual
if it is an Interface.
"../tb/top/sv/top_env.sv", 41: token is ';'
cl_syoscb m_reference_scoreboard;
^

Does anyone know what could be the cause?

I'm sorry if this is a silly question but I'm quite inexperienced in uvm and in system verilog in general.

When I upgraded the versions of everything on EDA Playground earlier this year, I could not get the Syosil scoreboard to work anymore. So, I am sorry, it is not supported anymore. So, it is not in any way a stupid question. Sorry for wasting your time.

Okay, thank you very much for your quick response.
