Autocomplete not working

[s3rgeym]

• I installed extension;
• I insalled luacheck;
• I added "lua.luacheckPath": "/usr/bin/luacheck" in my settings.json ;
• I setup environment variables LUA_PATH and LUA_CPATH;
• I created file test.lua:

local q = 'Qwerty'
-- Then i typed «q:lo» and and auto-completion didn't work

@trixnz Similar question how do I get autocomplete to work and have it reference a third party library for the definitions?
