在文件中

package.path = '/usr/local/share/lua/5.1/?.lua;/usr/local/openresty/lualib/resty/?.lua;' package.cpath = '/usr/local/lib/lua/5.1/?.so;'

執行
local mysql = require "mysql" --正確
local mysql = require "resty.mysql" --報錯

去掉 package.path = '/usr/local/share/lua/5.1/?.lua;/usr/local/openresty/lualib/resty/?.lua;' package.cpath = '/usr/local/lib/lua/5.1/?.so;'

local mysql = require "mysql" --報錯
local mysql = require "resty.mysql" --正確

package.path 的默認路徑指向哪的呢？

去掉?package.path，在頁面中 隨便引用一個不存在的模塊 比如 require 'aa'

查看nginx錯誤日志返回

no field package.preload['aa']no file '/usr/local/openresty/lualib/aa.lua'no file '/usr/local/openresty/lualib/aa/init.lua'no file './aa.lua'no file '/usr/local/openresty/luajit/share/luajit-2.1.0-alpha/aa.lua'no file '/usr/local/share/lua/5.1/aa.lua'no file '/usr/local/share/lua/5.1/aa/init.lua'no file '/usr/local/openresty/luajit/share/lua/5.1/aa.lua'no file '/usr/local/openresty/luajit/share/lua/5.1/aa/init.lua'no file '/usr/local/openresty/lualib/aa.so'no file './aa.so'no file '/usr/local/lib/lua/5.1/aa.so'no file '/usr/local/openresty/luajit/lib/lua/5.1/aa.so'no file '/usr/local/lib/lua/5.1/loadall.so'

發現 ?/usr/local/openresty/lualib/aa.lua 難道默認的路徑是?/usr/local/openresty/lualib 于是在頁面中加入

package.path = '/usr/local/share/lua/5.1/?.lua;/usr/local/openresty/lualib/resty/?.lua;/usr/local/openresty/lualib/?.lua;'

package.cpath = '/usr/local/lib/lua/5.1/?.so;'

ngx.say(package.path)

執行正確

新手~~ 勿怪
