在 Eclipse 中使用 luasocket 时出错 (Ubuntu 16.04)

Question

我正在尝试在安装在 Ubuntu 16.04 的 Eclipse Luna 中使用 Lua 5.1 和 lua 套接字。

我已经安装了 Lua 5.1 和 LuaSocket 3.0-rc1，我可以从命令行运行这个程序（lua main.lua ):

print(_VERSION)
print("Path: "..package.path..'\nCPATH: '..package.cpath)
socket = require("socket")
print(socket._VERSION)

结果是：

$ lua main.lua
Lua 5.1
Path: ./?.lua;/usr/local/share/lua/5.1/?.lua;/usr/local/share/lua/5.1/?/init.lua;/usr/local/lib/lua/5.1/?.lua;/usr/local/lib/lua/5.1/?/init.lua;/usr/share/lua/5.1/?.lua;/usr/share/lua/5.1/?/init.lua
CPATH: ./?.so;/usr/local/lib/lua/5.1/?.so;/usr/lib/x86_64-linux-gnu/lua/5.1/?.so;/usr/lib/lua/5.1/?.so;/usr/local/lib/lua/5.1/loadall.so
LuaSocket 3.0-rc1

但是当我尝试使用安装了 lua 插件的 eclipse 运行相同的程序时，我得到了这个：

Lua 5.1
Path: ;./?.lua;/usr/local/share/lua/5.1/?.lua;/usr/local/share/lua/5.1/?/init.lua;/usr/local/lib/lua/5.1/?.lua;/usr/local/lib/lua/5.1/?/init.lua;/usr/share/lua/5.1/?.lua;/usr/share/lua/5.1/?/init.lua;/media/meslin/16E65872E6585459/Users/meslin/Google Drive/workspace-desktop-ubuntu/Lua Alo Mundo/src/?.lua;/media/meslin/16E65872E6585459/Users/meslin/Google Drive/workspace-desktop-ubuntu/Lua Alo Mundo/src/?/init.lua;/media/meslin/16E65872E6585459/Users/meslin/Google Drive/workspace-desktop-ubuntu/Lua Alo Mundo/src/?.luac;/media/meslin/16E65872E6585459/Users/meslin/Google Drive/workspace-desktop-ubuntu/Lua Alo Mundo/src/?/init.luac;

有什么想法吗？你能帮帮我吗？

谢谢亚历山大

Answer 1

前段时间discussed on the lua maillist也有同样的问题，看看那里的推荐对你有没有帮助：

By default, LDT ships with a built-in Lua VM (based on jnLua) so as anyone without even having to install Lua on its machine can start running Lua scripts real quick. I think that the way you've set the PATH and CPATH, the jnLua VM itself is not found anymore.

What you probably want is to configure a "local interpreter" for your local native VM. You can use [1] as a reference. Once you have the interpreter set up, you can launch the script against this interpreter instead of the embedded jnLua one by tweaking your launch configuration.
