How can i install sourcemod

Can you give a gmod can install sourcemod version?
Very thank

Your looking to get a source mods content in Garry’s mod?
You could copy the mods folder into the addons folder so it acts like a addon

Nope ,i can’t do that
Because if my server inatall new sourcemod plugins
My server often crashes
Cannot open server

SourceMod doesnt work all that great with GMod.

All of the stuff SouceMod can do GMod LUA can do better. I would advise you to look into alternatives that are written in GMod LUA (check out Evolve, its pretty nice and in my opinion better than other GMod admin mods like ULX).
