module 'bit' not found

Hello, I installed torch as #10 mentioned but still can't run the demo. The result looks like:
`XX::~/AlphaPose$ ./run.sh --indir examples/demo/ --outdir examples/results/ --gpu 0,1,2,3 --batch 5

I try to google it. But there is no module named "bit"... Module "bit32" have been installed with lua2.
So.. Could anyone give any suggestion?
Many thanks~

Hi, try
luarocks install luabitop

[JustLuoxi]

THX, it really works~
And then I get two problems(fixed):

1. ffi.lua:56: expected align(#) on line 579 ==> change the gcc version to 4.8:
   sudo apt-get update
   sudo apt-get install gcc-4.8
   sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.8 999

2. AlphaPose/predict/img.lua:416: attempt to call global 'unpack' (a nil value) ==> find the file, and change all the 'unpack' to 'table.unpack'

Hope these solutions above can help someone.
Happy Chinese new year~~
