报错： loop or previous error loading module 'lrucache'

Start with the lua_package_path configuration and the require call in http_access.lua, then reproduce the reported error using the listed nginx and ngx_lua_module versions. Done means the resty.lrucache module loads successfully and the cache operations run without the reported loop or previous-error message.
