how can i solve the problem?

I suspect node-gyp can't download the SDK from nodejs.org, possibly because something in your network is blocking the outgoing connection. Can you try again with --verbose and post the full output?

I install truffle use cnpm command
but the output of truffle version is

fs.js:640
  return binding.open(pathModule._makeLong(path), stringToFlags(flags), mode);
                 ^

and the output of sudo truffle version is
Truffle v2.0.8
do I install truffle correctly?

[bnoordhuis]

I don't know. You should take that up with the truffle maintainers.

I had the same problem (read ECONNRESET) trying to install truffle. However, I was able to install node-gyp (global) and then install truffle.

The error seems to originate from a scrypt post install script or maybe a crypto module of it, used by secp256k1. I once saw the following error:

npm ERR! Linux 4.4.0-31-generic
npm ERR! argv "/usr/bin/nodejs" "/usr/bin/npm" "run" "rebuild"
