Question

我试图启动Rails服务器，但是我收到以下错误并且服务器关闭了。我怀疑我错过了一个依赖，但我是一个Ruby noob，所以我很可能是错的。

 => Booting WEBrick
 => Rails 4.1.0 application starting in development on `http://0.0.0.0:3000`
 => Run `rails server -h` for more startup options
 => Notice: server is listening on all interfaces (0.0.0.0). Consider using 127.0.0.1 (--binding option)
 => Ctrl-C to shutdown server 
    Exiting

更新：我没有＆＃34; execjs＆＃34;或＆＃34; therubyracer＆＃34;我的Gemfile中的宝石。这就是我所拥有的：

source 'https://rubygems.org'
ruby '2.1.1'
#ruby-gemset=railstutorial_rails_4_0

gem 'rails', '4.1.0'

group :development do
  gem 'sqlite3', '1.3.8'
end

gem 'sass', '3.3.6'
gem 'sass-rails', '4.0.1'
gem 'uglifier', '2.1.1'
gem 'coffee-rails', '4.0.1'
gem 'jquery-rails', '3.0.4'
gem 'turbolinks', '1.1.1'
gem 'jbuilder', '1.0.2'
gem 'haml'
gem 'railties'
gem 'faraday', '~> 0.9.0'
gem 'annyang_rails'
gem 'savon', '~> 2.3.0'
gem 'httparty'
gem 'speechcloud', '~> 0.1.1'
gem 'json', '~> 1.8.1'
gem 'sinatra', '~> 1.4.5'
gem 'rack', '~> 1.4'
gem 'rack-protection', '~> 1.4'
gem 'permutation', '~> 0.1.8'
gem 'tilt', '~> 1.3'
gem 'bacon', '~> 1.2.0'
gem 'activesupport', '~> 4.1.0'

group :doc do
  gem 'sdoc', '0.3.20', require: false
end

group :production do
  gem 'pg', '0.17.1'
  gem 'rails_12factor', '0.0.2'
end

就启动Rails服务器而言，我只需输入Rails Server。没有其他的。

顺便说一句，如果你不能说，我对RoR很新。

Answer 1

log_to_stdout': undefined method 'formatter' for nil:NilClass (NoMethodError)

这是你的错误，正如评论中所指出的那样，它似乎是logger

的问题

我只能推测问题可能是依赖（可以发布你的Gemfile），还是你的环境（没有正确安装ruby或者其他东西）

您可以为我们发布Gemfile吗？

Answer 2

所以，我终于想出了一个解决方案。感谢您让我走上正轨。我最终将问题追溯到我的config.ru文件。我改成了：

require ::File.expand_path('../config/environment',  __FILE__)
require './app'
run Sinatra::Application

这最终让Rails服务器启动并运行。
