问题
Note: my auto answer at end of the post
I'm trying to make a better experience of nodeJS and i don't really like to get all the script in one file.
so, following a post here i use this structure
./
config/
enviroment.js
routes.js
public/
css/
styles.css
images
views
index
index.jade
section
index.jade
layout.jade
app.js
My files are right now:
app.js
var express = require('express');
var app = module.exports = express.createServer();
require('./config/enviroment.js')(app, express);
require('./config/routes.js')(app);
app.listen(3000);
enviroment.js
module.exports = function(app, express) {
app.configure(function() {
app.use(express.logger());
app.use(express.static(__dirname + '/public'));
app.set('views', __dirname + '/views');
app.set('view engine', 'jade'); //extension of views
});
//development configuration
app.configure('development', function() {
app.use(express.errorHandler({
dumpExceptions: true,
showStack: true
}));
});
//production configuration
app.configure('production', function() {
app.use(express.errorHandler());
});
};
routes.js
module.exports = function(app) {
app.get(['/','/index', '/inicio'], function(req, res) {
res.render('index/index');
});
app.get('/test', function(req, res) {
//res.render('index/index');
});
};
layout.jade
!!! 5
html
head
link(rel='stylesheet', href='/css/style.css')
title Express + Jade
body
#main
h1 Content goes here
#container!= body
index/index.jade
h1 algoa
The error i get is:
Error: Failed to lookup view "index/index" at Function.render (c:\xampp\htdocs\nodejs\buses\node_modules\express\lib\application.js:495:17) at render (c:\xampp\htdocs\nodejs\buses\node_modules\express\lib\response.js:614:9) at ServerResponse.render (c:\xampp\htdocs\nodejs\buses\node_modules\express\lib\response.js:638:5) at c:\xampp\htdocs\nodejs\buses\config\routes.js:4:7 at callbacks (c:\xampp\htdocs\nodejs\buses\node_modules\express\lib\router\index.js:177:11) at param (c:\xampp\htdocs\nodejs\buses\node_modules\express\lib\router\index.js:151:11) at pass (c:\xampp\htdocs\nodejs\buses\node_modules\express\lib\router\index.js:158:5) at Router._dispatch (c:\xampp\htdocs\nodejs\buses\node_modules\express\lib\router\index.js:185:4) at Object.router [as handle] (c:\xampp\htdocs\nodejs\buses\node_modules\express\lib\router\index.js:45:10) at next (c:\xampp\htdocs\nodejs\buses\node_modules\express\node_modules\connect\lib\proto.js:191:15)
But i don't really know what is the problem...
I'm starting thinking is because the modules exports...
Answer: Far away the unique solution i found is to change the place i defined app.set('views') and views engine
I moved it to the app.js and now is working well.
var express = require('express');
var app = module.exports = express.createServer();
require('./config/enviroment.js')(app, express);
app.set('views', __dirname + '/views');
app.set('view engine', 'jade');
require('./config/routes.js')(app);
app.listen(3000);
I don't really understand the logic behind this but i gonna supose it have one.
回答1:
npm install express@2.5.9 installs the previous version, if it helps.
I know in 3.x the view layout mechanic was removed, but this might not be your problem. Also replace express.createServer() with express()
Update:
It's your __dirname from environment.js
It should be:
app.use(express.static(__dirname + '../public'));
回答2:
Adding to @mihai's answer:
If you are in Windows, then just concatenating __dirname' + '../public' will result in wrong directory name (For example: c:\dev\app\module../public).
Instead use path, which will work irrespective of the OS.
var path = require ('path');
app.use(express.static(path.join(__dirname + '.../public')));
path.join will normalize the path separator character and will return correct path value.
回答3:
I had the same error at first and i was really annoyed.
you just need to have ./ before the path to the template
res.render('./index/index');
Hope it works, worked for me.
回答4:
It is solved by adding the following code in app.js file
app.engine('html', require('ejs').renderFile);
app.set('view engine', 'html');
app.set('views', __dirname);
app.get('/', function(req, res){
res.render("index");
});
回答5:
Check if you have used a proper view engine. In my case I updated the npm and end up in changing the engine to 'hjs'(I was trying to uninstall jade to use pug). So changing it to jade from hjs in app.js file worked for me.
app.set('view engine','jade');
回答6:
use this code to solve the issue
app.get('/', function(req, res){
res.render("index");
});
回答7:
Just noticed that I had named my file ' index.html' instead for 'index.html' with a leading space. That was why it could not find it.
回答8:
This problem is basically seen because of case sensitive file name. for example if you save file as index.jadge than its mane on route it should be "index" not "Index" in windows this is okay but in linux like server this will create issue.
1) if file name is index.jadge
app.get('/', function(req, res){
res.render("index");
});
2) if file name is Index.jadge
app.get('/', function(req, res){
res.render("Index");
});
回答9:
You could set the path to a constant like this and set it using express.
const viewsPath = path.join(__dirname, '../views')
app.set('view engine','hbs')
app.set('views', viewsPath)
app.get('/', function(req, res){
res.render("index");
});
This worked for me
回答10:
I change the views folder name to views_render and also facing the same issue as above, so restart server.js and it works for me.
回答11:
This error really just has to do with the file Path,thats all you have to check,for me my parent folder was "Layouts" but my actual file was layout.html,my path had layouts on both,once i corrected that error was gone.
回答12:
I had the same issue and could fix it with the solution from dougwilson: from Apr 5, 2017, Github.
- I changed the filename from
index.jstoindex.pug - Then used in the
'/'route:res.render('index.pug')- instead ofres.render('index') - Set environment variable:
DEBUG=express:viewNow it works like a charm.
回答13:
I had this issue as well on Linux
I had the following
res.render('./views/index')
I changed it too
res.render('../views/index')
Everything is now working.
