Installation problem

[gelnior]

Hello,

On Ubuntu 14.04, I installed Lua 5.2 and luarocks via apt-get. After installing Moonscript via luarocks, I run into the following error when I use the moonc command:

/usr/bin/lua: /usr/share/lua/5.1//luarocks/loader.lua:113: error loading module 'lfs' from file '/usr/local/lib/lua/5.1/lfs.so':
    /usr/local/lib/lua/5.1/lfs.so: undefined symbol: luaL_register
stack traceback:
    [C]: in function 'loader'
    /usr/share/lua/5.1//luarocks/loader.lua:113: in function </usr/share/lua/5.1//luarocks/loader.lua:110>
    (...tail calls...)
    [C]: in function 'require'
    /usr/local/lib/luarocks/

Do you have any idea of what I did wrong?

I like coding in Coffeescript, so I think Moonscript is a great idea for Lua.

I have the same problem.

Make sure you are using the lua5.1 package instead of the lua5.2 package. Try:

sudo apt-get install lua5.1
sudo apt-get remove lua5.2

You should see a message from update-alternatives noting that it will use lua5.1 and luac5.1.

Ok. Thank you @suchipi.

Same here, with a slightly different error:

/usr/bin/lua: /usr/share/lua/5.1//luarocks/loader.lua:113: error loading module 'lpeg' from file '/usr/local/lib/lua/5.1/lpeg.so':
    /usr/local/lib/lua/5.1/lpeg.so: undefined symbol: lua_tointeger

Thanks for the fix.

MoonScript should work fine on all versions of Lua. It seems like there's a luarocks environment problem, it's trying to use modules compiled for another version of Lua.

@gelnior @leafo can someone close this?
