“意外的输入结束，期待keyword_end（SyntaxError）”RSpec 3，Rails 4.1.6，Ruby 2.0

Question

我想指出一个Users控制器，使用RSpec 3.1.7，我不断收到unexpected end-of-input SyntaxError。我结束了“剥离”整个控制器的第一describe，正好看到哪一行导致了问题，像这样：

require 'rails_helper' 

RSpec.describe UsersController, :type => :controller do 

end 

这里是确切的错误：

这里是我的rails_helper.rb：

ENV["RAILS_ENV"] ||= 'test' 
require 'spec_helper' 
require File.expand_path("../../config/environment", __FILE__) 
require 'rspec/rails' 
require 'capybara/rails' 
require 'ffaker' 

ActiveRecord::Migration.maintain_test_schema! 

RSpec.configure do |config| 
    # Factory_Girl Init 
    config.include FactoryGirl::Syntax::Methods 

    config.fixture_path = "#{::Rails.root}/spec/fixtures" 
    config.use_transactional_fixtures = false 
    config.infer_spec_type_from_file_location! 

    # DatabaseClener config 
    config.before(:suite) do 
    DatabaseCleaner.clean_with(:truncation) 
    end 

    config.before(:each) do 
    DatabaseCleaner.strategy = :transaction 
    end 

    config.before(:each, :js => true) do 
    DatabaseCleaner.strategy = :truncation 
    end 

    config.before(:each) do 
    DatabaseCleaner.start 
    end 

    config.after(:each) do 
    DatabaseCleaner.clean 
    end 
end 

，这里是我的 'spec_helper.rb'

RSpec.configure do |config| 

    config.expect_with :rspec do |expectations| 
    expectations.include_chain_clauses_in_custom_matcher_descriptions = true 
    end 

    config.mock_with :rspec do |mocks| 
    mocks.verify_partial_doubles = true 
    end 
end 

我运行：

• 红宝石2.0
• 的Rails 4.1.6
• RSpec的3

Answer 1

语法错误似乎是在你的控制文件，而不是控制器规范或规范帮手。

/app/controllers/users_controller.rb:20: syntax error, unexpected end-of-input, expecting keyword_end (SyntaxError) 

您可以使用-c红宝石标志检查单个文件的语法。

$ ruby -c app/controllers/users_controller.rb 
Syntax OK 

输出将声明语法为OK，或者会给您类似于您当前正在接收的错误消息。
