How to resove error-"Application Installer abnormal process termination. Process exit value was 8" in titanium?

hii,all I have made a project in android alloy framework, but after installing some titanium updates i encounter with problem of running alloy projects :(CLI version 4.0.0, Titanium SDK version 3.4.1.GA )

this error occured - Unhandled 'error' event ^ Error: spawn ENOENT at errnoException (child_process.js:1001:11) at ChildProcess._handle.onexit (child_process.js:792:34)

[ERROR] Application Installer abnormal process termination. Process exit value was 8

Then I resolved it by running following command on cmd : npm install -g alloy

But still facing following problem, Don't know how to resolve it :

          ^
