Can’t find the module? Which ‘- Cordova Android

cordova -d build android

module.js:340
throw err; 
Error: Cannot find module'which' 
at Function.Module._resolveFilename (module.js:338:15) 
at Function.Module._load (module.js:280:25) 
at Module.require (module.js:364 :17) 
at require (module.js:380:17)

I am trying to build my cordova build by executing the following commands

cordova -d build android

But I found out by mistake.

module.js:340< br />throw err; 
Error: Cannot find module'which' 
at Function.Module._resolveFilename (module.js:338:15) 
at Function.Module._load (module. js:280:25) 
at Module.require (module.js:364:17) 
at require (module.js:380:17)

Who knows the reason? I checked that there is my ANT_HOME/ANDROID_HOME in my path, but I am not sure what is the reason behind the error.

By the way, I am running Windows 7 64-bit

Similar to the answer to this question, my solution is

$cordova platform remove android
$ cordova platform add android
