lua5.2怎么使用require包含外部脚本文件package.path=package.pat

你运行lua时，test1.lua和test2.lua是在当前目录下吗？

Plain Text code
?

/tmp/ cat test1.lua
package.path = package.path .. ";./?.lua"
local test2 = require("test2")

/tmp/ ~/tmp/lua-5.2.2/src/lua test1.lua # 没问题

/tmp/ rm test2.lua # 删掉test2.lua

/tmp/ ~/tmp/lua-5.2.2/src/lua test1.lua # 报错了
