Printer.js不打印到控制檯

因此，出於某種原因，在將我的打印功能移動到他們自己的文件並嘗試在我的app.js文件上運行節點命令後，突然間它不想打印任何東西在我的控制檯。這是爲什麼？Printer.js不打印到控制檯

我仍在努力調試這一個，因爲當我運行以下命令時沒有打印出任何內容。

node app.js myusernamehere

任何人有什麼想法？

app.js

var profile = require("./profile.js"); 
var users = process.argv.slice(2); 

users.forEach(profile.get);

profile.js

//Problem: We need a simple way to look at a user's badge count and Javascript points 
//Solution: Use Node.js to connect to Treehouse's API to get profile information to print out 
var https = require("https"); 
var http = require("http"); 
var printer = require("./printer.js"); 

function get(username) { 
    //Connect to API URL (http://teamtreehouse.com/username.json) 
    var request = https.get("https://teamtreehouse.com/" + username + ".json", function(response) { 
     var body = ""; 
     //Read the data 
     response.on('data', function(chunk) { 
      body += chunk; 
     }); 
     response.on('end', function() { 
      if (response.statusCode == 200) { 
       try { 
        //Parse the data 
        var profile = JSON.parse(body); 
        //Print the data 
        printer.printMessage(username, profile.badges.length, profile.points.JavaScript); 
       } catch(error) { 
        //Parse Error 
        printer.printError(error); 
       } 
      } else { 
       //Status Code Error 
       printer.printError({message: "There was an error getting the profile for " + username + ". (" + http.STATUS_CODES[response.statusCode] + ")"}); 
      } 
     }); 
    }); 

    //Connection Error 
    request.on('error', printer.printError); 
} 

module.exports.get = get;

printer.js

//Print out message 
function printMessage(username, badgeCount, points) { 
    var message = username + " has " + badgeCount + " total badge(s) and " + points + " points in Javascript"; 
    console.log(message); 
} 

//Print out error messages 
function printError(error) { 
    console.error(error.message); 
} 

module.exports.printMessage = printMessage; 
module.exports.printError = printError;

任何人有任何想法，爲什麼沒有打印出來？ – user3732216

我不知道是什麼ACTU盟友發生了，但現在起作用，我的代碼中沒有任何東西被改變。
