我是 Lua 新手，不习惯在 Windows 上编译东西.

I'm new to Lua, and I'm not used to compiling stuff on Windows.

无论如何，luasocket 的安装没有错误地完成，使用 MS Visual Studio 2010 编译所有东西.不得不从 Visual Studio 命令提示符运行 luarocks，但最终工作.

Anyway the installaion of luasocket finished without errors, compiling all the stuff with MS Visual Studio 2010. Had to run luarocks from the Visual Studio Command Prompt, but it finally worked.

但是当我尝试要求它时，我遇到了错误.

But when I try to require it, I drive into an error.

> require 'socket'
error loading module 'socket.core' from file 'C:Program Files (x86)LuaRockssystree/lib/lua/5.1/socketcore.dll':
        C:Program Files (x86)LuaRockssystree/lib/lua/5.1/socketcore.dll:1: '=' expected near 'É'
stack traceback:

        [C]: in function 'require'
        ...iles (x86)LuaRockssystree/share/lua/5.1/socket.lua:12: in main chunk
        [C]: in function 'require'
        stdin:1: in main chunk
        [C]: ?

使用 require 'luarocks.loader' 也无济于事，同样的错误.我想无论如何我都不需要它，因为我已经使用 luarocks 路径设置了 LUA_PATH

Using require 'luarocks.loader' doesn't help either, same error. I think I don't need it anyway, because I have LUA_PATH set up with the luarocks paths

我搜索了几个小时都没有结果.我还尝试安装旧版本的 Luasockets，但它需要 Visual Studio 2003，所以我想避免这种情况.

I searched for hours with no results. I also tried to install an older version of Luasockets but it requires Visual Studio 2003, so I would like to avoid that.

推荐答案

看起来 Lua 正在尝试将 DLL 解析为 Lua 代码.如果 package.path(或 LUA_PATH 环境变量)包含 ?.dll 路径模板，就会发生这种情况.请从 package.path 中删除所有 ?.dll 模板并将它们放入 package.cpath(或 LUA_CPATH环境变量).

It looks like Lua is trying to parse the DLL as Lua code. This can happen if package.path (or the LUA_PATH environment variable) contains ?.dll path templates. Please remove all ?.dll templates from package.path and put them into package.cpath (or the LUA_CPATH environment variable).
