Problem solved. The reason is a mistaken sequence I made, which cause LuaJIT choosing lua_package_path not as desire `/apisix-3.2.0/apisix/plugins/prometheus.lua:39: attempt to index local 'exporter' (a number value)` The reason of the error log above is that I add a `lua_extra_path` config to my `conf/config.yaml` file, which is: `extra_lua_path: "/chj/apisix-3.2.0/apisix/plugins/?.lua"` then when APISIX running, the `lua_package_path` becomes: `/chj/apisix-3.2.0/apisix/plugins/?.lua;/chj/apisix-3.2.0//deps/share/lua/5.1/?.lua;/chj/apisix-3.2.0//deps/share/lua/5.1/?/init.lua;...` so as the error stack shows, `apisix/plugins/prometheus/exporter.lua:20` tries to find the `prometheus` module. The lua-land will firstly try to find it in `/chj/apisix-3.2.0/apisix/plugins/?.lua`(the left head of `lua_package_path`), then `/chj/apisix-3.2.0//deps/share/lua/5.1/?.lua`. lua-land will hit `/chj/apisix-3.2.0/apisix/plugins/prometheus.lua` then use it. But the real file the `exporter.lua` wanna to find is `/chj/apisix-3.2.0//deps/share/lua/5.1/prometheus.lua`(The behind but the RIGHT module)... -- This is an automated message from the Apache Git Service.
