I have tried everything but still can not require file in Lua. I am using LuaEdit 2010 on Windows 8.1
Relative path is still not working. I used these commands, which i have found but I still get the error below. My file is C:\Lua\file.lua, but I need to use relative path.
package.path = package.path .. ";../?.lua"
require ("file.lua") --also require ("file")
My error is:

do not write about Linux, I saw: Torch test.sh, /usr/bin/lua: module 'paths' not found
Does anyone have file: paths.lua?
I also got this same error I find a solution from stackoverflow.
By Adding. /torch/install/bin/torch-activate
in your bashrc file and makes the test.sh script run.
I have a folder containing main.lua opened in Sublime Text, but when I try to compile it in the text editor, it gives me this error. I have no problem running the code in the game engine. Can someone tell me what I am doing wrong and how to fix it in layman's terms? I am new to coding. Here is the full error:

I've downloaded the module scokets in the official lua web page and added this module to the Lua Eclipse. I'm using lua 5.1 in the Eclipse with lua socket 2.0.2 (luasocket-2.0.2-lua-5.1.2-Win32-vc8).
I don't understand what I need to do to solve this error.
Thank you very much
I am call lua in C++ applications. I have several lua files to call, like RunAPI_1208.lua , JSON.lua, etc. All the lua file is called by main.lua. While in C++ , I run all the file and finally run main.lua. I met this problem. I am using Cocos2d-x 2.2.6. How can I solve it?
[string "Main.lua"]:9: module 'RunAPI_1208' not found:
no field package.preload['RunAPI_1208']
no file './RunAPI_1208.lua'
no file '/usr/local/share/lua/5.1/RunAPI_1208.lua'

no file '/usr/local/lib/lua/5.1/RunAPI_1208/init.lua'
no file './RunAPI_1208.so'

no file '/usr/local/lib/lua/5.1/loadall.so'
Cocos2d: [string "Main.lua"]:9: module 'RunAPI_1208' not found:

no file './RunAPI_1208.lua'

no file './RunAPI_1208.so'
no file '/usr/local/lib/lua/5.1/RunAPI_1208.so'
no file '/usr/local/lib/lua/5.1/loadall.so'
And this is my main.lua:
local run = require("RunAPI_1208")
I'm quite new to Lua and I have some problems with the import mechanism.
From other languages I'm used to do something like this:
include "./lib/mylib.h"
or in general just to pass the local path to the file I would like to include.
Now in Lua it is a bit confusing to me. I read something about that require looks for the library in the lua path.
In my case I would like to create a script that uses the luasocket library but I would like to import it from a local path so that I can deploy it without the need to have it on another machine in the lua path.
From other forums I got solutions like creating a local require function that looks in a given local library folder but that didn't work.
Then I read that I can just type require 'myfile' to import a different file locally but luasocket requires a core.dll and if I just move the lua files of the library to my local path it can't find the dll.
Is there an easy way to solve this. What do I have to do to get this working?
It is sufficient for the .dll extension to be in the LUA_CPATH (so it ends up in package.cpath). For example, put the socket.lua in C:\Foo, and put core.dll in same folder. Then require 'socket' will fail:
> print(package.cpath)
.\?.dll;.\?51.dll;C:\Program Files\Lua\5.1\?.dll;C:\Program Files\Lua\5.1\?51.dl

because socket.lua requires socket.core, so Lua interpreter looks for core.lua in a "socket" folder anywhere on package.path, doesn't find it (socket folder doesnt' exist), then looks for core.dll in socket folder anywhere on package.cpath, same problem.
Now create C:\Foo\socket folder, and move core.dll to it, then require 'socket' will work (from interpreter started while cd to C:\Foo).
In your case, if you have yourLuaScript.lua in C:\Foo, you could have socket.lua in same folder, core.dll in C:\Foo\socket, and yourLuaScript.lua could require 'socket' and, as long as package.path contains .\*.lua, and package.cpath contains .\*.dll, you will be able to run yourLuaScript.lua.
