我是Lua的新手，而且我不习惯在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的安装均无错误，使用MS Visual Studio 2010编译了所有内容.必须从Visual Studio命令提示符运行luarocks，但最终成功了.

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，我会遇到错误.

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)\LuaRocks\systree/lib/lua/5.1/socket\core.dll':
        C:\Program Files (x86)\LuaRocks\systree/lib/lua/5.1/socket\core.dll:1: '=' expected near 'É'
stack traceback:

        [C]: in function 'require'

        [C]: in function 'require'
        stdin:1: in main chunk
        [C]: ?

使用require 'luarocks.loader'也无济于事，出现同样的错误.我想我还是不需要它，因为我已经使用luarocks路径

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

我搜索了数小时却没有结果.我还尝试安装一个旧版本的Luasockets，但是它需要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

Lua似乎试图将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，则可能发生这种情况.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).
