Error in running Torch/Lua, maybe an installation error

I installed Torch following http://torch.ch/docs/getting-started.html.

However, when I run things like "th" or any simple code, I got the following error message:

/Users/JianxuChen/torch/install/bin/luajit: ...rs/JianxuChen/torch/install/share/lua/5.1/trepl/init.lua:692: attempt to call field 'setheaptracking' (a nil value) stack traceback: ...rs/JianxuChen/torch/install/share/lua/5.1/trepl/init.lua:692: in main chunk [C]: in function 'require' ...Chen/torch/install/lib/luarocks/rocks/trepl/scm-1/bin/th:104: in main chunk [C]: at 0x01089f8bc0

Does anyone have ever encountered similar issue, or have any idea about how to solve it?

Thanks!

Torch heap tracking has been introduced quite a while ago (see this) and recently enabled by default on trepl (see this), so this is strange. Is it a fresh install or an update? If you run pushd ~/torch/pkg/torch/ && git rev-parse HEAD what do you get? – deltheil
@deltheil, I got ~/torch/pkg/torch ~/torch 840e7312e51e3dd6e28583d4020bfe134eadb9cf The error is still not solved. Is it possible that some errors occur during installation? The log file (install.log) generated during installation is attached at : drive.google.com/file/d/0BzY6rRCk_ItCLVctN05TeWE5UlE/… – Jianxu
So you have a recent enough torch version (which is normal if you cloned torch/distro recently). That said your install log is not complete: it looks like it stopped after lua-cjson install (i.e. here). – deltheil

I met the same problem and solved it in this way. Your torch is not the latest version. What I do is NOT follow this http://torch.ch/docs/getting-started.html. Instead download https://github.com/torch/distro and run ./install. Then it works!
