Question

在本地运行this Express应用正常工作。在Heroku上运行它会在请求/或/nested

时发出粘贴错误

在我的服务器文件中：

express = require 'express'
app = express()

app.configure () ->

  app.set 'views', __dirname + '/views'
  app.set 'view engine', 'jade'

  app.use express.logger('dev')
  app.use express.bodyParser()
  app.use express.methodOverride()
  app.use express.cookieParser()
  app.use express.session(
    secret: 'WTF'
  )
  app.use app.router
  app.use express['static'](process.cwd() + '/public')

  app.get '/', (req, res) ->

    res.render 'index'

  app.get '/nested', (req, res) ->

    res.render 'nested/index'

port = process.env.PORT || 3000

app.listen port, () -> 
  console.log 'Server started on ' + port + '\nPress CTRL-C to stop server.'

在本地，我不需要为运行的服务器指定app.set 'views', __dirname + '/views'并查找文件 - 无论是否有Heroku，它都无法使用。

关于你的编辑：

问题可能是个案。字符串指定小写路径：

文件实际上是大写的：

您的本地系统似乎使用不区分大小写的文件系统，而Heroku则没有。

要帮助快速查找您的观看次数，您可以设置'views'根路径：

app.set('views', __dirname + '/views');

您也可以将绝对路径传递给res.render()：

res.render(__dirname + '/views/admin/login');

另请注意，您可能不需要（也可能不想）将req和res传递给res.render()：

app.get('/admin/login', function (req, res) {
    res.render('admin/login');
});

使用它们，req的属性将在locals中包含在res中callback，因为function将被忽略或导致错误，因为它不是{{1}}。

在Heroku上找不到玉模板
