Lua on redis错误:脚本试图访问未显示的全局变量'require'

Question

这是我试图执行的测试脚本:

local cjson = require "cjson"
local json_text = '[ true, { "foo": "bar" } ]'
local value = cjson.decode(json_text)
return 'Decoded: ' .. value

它给出了一个奇怪的回应:

evalsha 76b573109be38414056b58c749016a56052063bd 0
(error) ERR Error running script (call to f_76b573109be38414056b58c749016a56052063bd): @enable_strict_lua:15: user_script:1: Script attempted to access unexisting global variable 'require'

为什么编译器无法理解关键字"require"？我正在使用redis 3.0.5(运行Lua 5.1)

Answer 1

require在Redis中不可用,库已预先加载.只需删除脚本的第一行即可.
