SyntaxError: acorn.js处的意外标记

Question

我尝试用express.js和jade模板创建登录表单，然后发现如下错误：

SyntaxError: Unexpected token (16:50)
    at Parser.pp.raise (C:\project\restaurant\node_modules\acorn\dist\acorn.js:943:13)
    at Parser.pp.unexpected (C:\project\restaurant\node_modules\acorn\dist\acorn.js:1503:8)

这是我的layout.jade代码

doctype html

html

        head
                title #{Project Restaurant Finder} 
                link(rel='stylesheet', href='/stylesheets/style.css')
        body
                block content   
        Footer
                p contact : aliwumpa@gmail.com or 081222843778

这是我的index.jade代码

extends layout

block content

h1 = login form

    form(name ="login restaurant finder",method ="post")
        div.input
            span.label Login as Guest
            input(type="text", name="username")
        div.actions
            input(type="submit", value="ok")

在评论中回答由gandreadis提供：

这个部分的title #{Project Restaurant Finder}肯定需要修复:要么更改为title Project Restaurant Finder，要么更改为title #{variable_name}，其中variable_name是传递给模板的变量，用于为模板提供标题。
