通过peepcode nodejs视频并在当前快递/节点版本上重新创建应用程序我遇到了一个小问题。
文件结构
site
- apps
- - authentication
- - - views
- - - - login.jade
- - - routes.js
- node_modules
- public
- - images
- - javascripts
- - stylesheets
- routes
- views
app.js
login.jade:
extends /views/layout
block content
form(action='/sessions', method='post')
label
| Username
input(type='text', name='user')
label
| Password
input(type='password', name='password')
input(type='submit', name='submit')
app.js
var express = require('express')
, user = require('./routes/user')
, http = require('http')
, path = require('path');
var app = express();
// all environments
app.set('port', process.env.PORT || 3000);
app.set('views', __dirname + '/views');
app.set('view engine', 'jade');
app.set('view options', { basedir: process.env.__dirname})
app.use(express.favicon());
app.use(express.logger('dev'));
app.use(express.bodyParser());
app.use(express.methodOverride());
app.use(app.router);
app.use(express.static(path.join(__dirname, 'public')));
require('./apps/authentication/routes')(app)
http.createServer(app).listen(app.get('port'), function(){
console.log('Express server listening on port ' + app.get('port'));
});
当我导航到localhost:3000/login
时,收到以下错误:
Error: /Users/bob/code/site/apps/authentication/views/login.jade:1
> 1| extends /views/layout
2| block content
3| form(action='/sessions', method='post')
4| label
the "basedir" option is required to use "extends" with "absolute" paths
我可以将extends行更新为:extends ../../../views/layout并使其正常工作,但我更愿意知道如何设置basedir选项。
答案 0 :(得分:24)
您可以使用:
app.locals.basedir = '/your/base/directory';
或者,使用较新的Express方法,
app.locals.basedir = path.join(__dirname, 'views');
答案 1 :(得分:8)
在快递中,你会发现有,
app.set('views', path.join(__dirname, 'views'));
你可以把这一行放在那里,
app.locals.basedir = app.get('views');
这使得基础可用于jade.js
,因此它可以解析绝对路径。
