这是我的 config.ru:
require 'sinatra'
require 'rack/contrib'
root_dir = File.dirname(__FILE__)
require File.join(root_dir,'app.rb')
set :environment, :development
log = File.new("log/sinatra.log","a+")
$stdout.reopen(log)
$stderr.reopen(log)
$stderr.sync=true
$stdout.sync=true
run Ivende.new
app.rb:
require 'sinatra'
require 'sinatra/reloader'
require 'time'
require 'json'
class Ivende < Sinatra::Application
enable :sessions
set :environment, :development
configure :production do
set :clean_trace,true
end
configure :development do
set :logging, true
end
helpers do
include Rack::Utils
end
require_relative 'models/init'
require_relative 'helpers/init'
require_relative 'routes/init'
end
内部路线我有这个文件:
class Ivende < Sinatra::Application
get "/" do
"HOME PAGE "
logger.info("foooooolanito")
end
end
我看到的奇怪行为是,当我使用记录器行调用主路线“/”时,资源管理器向我显示典型的乘客错误页面,并显示以下消息:
An error occurred while starting up the preloader: it did not write a startup response in time.
在 sinatra.log 文件中,我得到:
Ready !> socket:

在 Apache 日志中,我得到:

如果我从 config.ru 中删除这些行:
log = File.new("log/sinatra.log","a+")
$stdout.reopen(log)
$stderr.reopen(log)
$stderr.sync=true
$stdout.sync=true
和:
logger.info("foooooolanito")
然后我看到了我期望的主页文本。
这个项目是从一台安装了 Ruby 1.9.3-p327、Passenger 3.0.3、Sinatra 1.3.5 的机器上迁移过来的,它运行良好。
我能做些什么?
