Nodejs TypeError：undefined不是函數

Question

我在關注Treehouse Nodejs教程並遇到這個錯誤。服務器在路由器中的響應無法在渲染器中查找視圖方法。

router.js:10 
response.view("header", {}, response); 
    ^
TypeError: undefined is not a function 

renderer.js

var fs = require("fs"); 

function view(templateName, values, response) { 
    //Read from the template files 
    var fileContents = fs.readFileSync('./views/' + templateName + '.html'); 
    //Insert values in to the content 
    //Write out the contents to the response 
    response.write(fileContents); 
} 

module.exports.view = view; 

router.js

var Profile = require("./profile.js"); 
var renderer = require("./renderer.js"); 

//Handle HTTP route GET/and POST/i.e. Home 
function home(request, response) { 
    //if url == "/" && GET 
    if(request.url === "/") { 
    //show search 
    response.writeHead(200, {'Content-Type': 'text/plain'}); 
    response.view("header", {}, response); 
    response.write("Search\n"); 
    response.end("Footer\n"); 
} 
}

您還沒有router.js使用renderer任何地方。

我相信你打算打電話給renderer.view而不是response.view。
