静态文件路径

app.use(express.static(__dirname+'/public'));

页面引用路径

link(type='text/css',rel='stylesheet', href='/stylesheets/bootstrap.css')
link(type='text/css',rel='stylesheet', href='/stylesheets/bootstrap-responsive.css')
script(src="/javascripts/jquery.js")
script(src="/javascripts/bootstrap.js")

Answer 1

没有读写权限吧

Answer 2

__dirname+'/public'输出下看看。

用这个试试呢

const path = require('path');
app.use(express.static(path.join(__dirname, 'public')));

Answer 3

这里报的错是lazyrouter未定义，跟静态文件路径应该没问题。
我估计是你用lazyrouter的时候错了
