ruby-on-rails - Rails 服务器上的 NoMethodError

Question

我正在尝试启动 Rails 服务器，但出现以下错误并且服务器关闭。我怀疑我缺少依赖项，但我是 Ruby 菜鸟，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:我的 Gemfile 中没有“execjs”或“therubyracer”gem。这是我所拥有的:

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，我只是键入 Rails Server。没有其他的。

顺便说一句，如果您看不出来，我对 RoR 还很陌生。

Answer 1

log_to_stdout': nil:NilClass 的未定义方法'formatter'
(NoMethodError)

那是你的错误，正如评论中所指出的，它看起来像是 logger

的问题

我只能推测问题可能与依赖项有关(请发布您的Gemfile)，或与您的环境有关(没有正确安装 ruby​​ 或其他)

你能为我们发布你的 Gemfile 吗？
