Incorrect instruction for building jQuery

Incorrect instruction for building jQuery

I followed by this HOWTO link to build jQuery on my machine (Win 2008R2 x64), but when it comes to executing

  
cd jquery && npm install
it throws me the following exception in Bash cmd line:


$ cd jquery && npm install

module.js:340
    throw err;
          ^
Error: Cannot find module '\\node_modules\npm\bin\npm-cli.js'
    at Function.Module._resolveFilename (module.js:338:15)
    at Function.Module._load (module.js:280:25)
    at Function.Module.runMain (module.js:497:10)
    at startup (node.js:119:16)
    at node.js:901:3












I'm out of ideas how to resolve this issue. What's wrong with my environment?
