Rails 服务器上的 NoMethodError [英] NoMethodError on Rails Server

问题描述

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.我怀疑我缺少一个依赖项，但我是一个 Ruby 菜鸟，所以我很可能是错的.

I'm trying to start the Rails Server, but I get the following error and the server shuts down. I suspect I'm missing a dependency, but I'm a Ruby noob, so I very well could be wrong.

 => 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

更新:我的 Gemfile 中没有execjs"或therubyracer"宝石.这是我所拥有的:

UPDATED: I do not have "execjs" or "therubyracer" gems in my Gemfile. Here is what I have:

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

至于启动 Rails 服务器，我只需键入 Rails Server.没有其他的.

As far as starting Rails server, I simply type Rails Server. Nothing else.

顺便说一句，如果你不知道，我对 RoR 很陌生.

BTW, if you can't tell, I'm very new to RoR.

推荐答案

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

那是你的错误，正如评论中指出的，它看起来像 logger

That's your error, and as pointed out in the comments, it looks like a problem with the logger

我只能推测这个问题要么是依赖(你能不能发布你的 Gemfile)，要么是你的环境(没有正确安装 ruby​​ 或其他东西)

I can only surmise the issue will be with either a dependency (can you post your Gemfile please), or with your environment (not having ruby installed properly or something)

您可以为我们发布您的 Gemfile 吗?

Can you post your Gemfile for us?
