Error in Node.js Module.js 472 throw err;

I am creating an API on node, for request with my application. But this error appears, claiming that this folder does not exist, but in the code I'm not calling it anywhere.

module.js:472
    throw err;
    ^

Error: Cannot find module 'C:\Users\Ramon Lopes\Documents\API\NodeApi.js'
