Express.js, Node.js Jade vim

问题

Help, before I throw my beautiful, expensive MacBook Pro to the ground in a fit of annoyance.

I'm trying to get something working in Expressjs, and it's really getting on my nerves. I'm following the tutorial on: expressjs.com/screencasts.html

Screencast 2:

And I'm getting this error message:

Express
500 Error: /home/duncan/helloExpress/views/users.jade:4 2| p#users 3| - each user in users > 4| li user.name 5| expected "indent", but got "newline"

Please help, I get that it's getting a newline when it's expecting an indent by why? And how do I fix the blooming thing!!

My users.jade is as follows:

h1 Users
p#users 
    - each user in users
    li user.name

------------------

SO NOW THE ISSUE IS...

OK so now, it's been pointed out that I should be using a ul instead of a p (paragraph) element - pretty obvious once you notice it, though the error message, could be better.

However, I'm now getting the following errors: Though I'm now getting the following error:

Express

    * at next (/usr/local/lib/node/.npm/connect/1.4.0/package/lib/http.js:204:15)

My app.js code is as follows:

var users = [
    {   name: 'Duncan', email: 'duncan@email.com'},
    {   name: 'Bob',    email: 'bob@email.com'}
];

and...


app.get('/users', function(req, res){
  res.render('users', {
        users: users
  });

});

I don't know if I'm just being blind today, but I would really like to get this example working.

NB. app.js 46:7 is the 'res.render' char 7 is the . between res and render.

回答1:

I changed the p to a ul (p tags shouldn't have children). And I defined the users array in the jade ( which works well for testing ).

note the indentation after the - each and the li=.

- users = [ { name:'Duncan' }, { name: 'Henry'}, { name: 'Raynos' } ]
h1 Users
ul#users 
  - each user in users
    li= user.name

回答2:

ul
    - each item in sidebars
        li
          a(href=item.href,target='_self') !{item.name}

回答3:

sounds like it might have problems with significant whitespace.

Try

h1 Users
p#users 
- each user in users
li user.name

It might dislike your indenting. Also generally updating to later versions of jade / node / express can help.

回答4:

h1 Users
p#users 
- each user in users
  li user.name

Try that

回答5:

I too faced the same issue but my code was like this

Before

h2 All Users
ul
  each user in users
  li #{user.name}

After

h2 All Users
ul
  - each user in users
    li #{user.name}

It is the matter of adding - before each statement
