爲什麼RSpec在本規範中報告語法錯誤？

Question

當試圖運行rspec時，我在運行bundle exec rspec spec/models/user_spec.rb命令時不斷收到下面的錯誤消息。我搜索了類似的問題，並看到了輸入確切路徑並確保我在根目錄中的建議。都沒有工作。另外，我試過運行一個軟件包安裝。如果這是一個基本問題，我很抱歉。我是一個總noob。先謝謝您的幫助。

我的Gemfile如下：

source 'https://rubygems.org' 
ruby '2.0.0' 
gem 'rails', '4.0.5' 
gem 'bootstrap-sass', '2.3.2.0' 
gem 'sprockets', '2.11.0'

gem 'faker', '1.1.2' 
gem 'will_paginate', '3.0.4' 
gem 'bootstrap-will_paginate', '0.0.9' 
group :development, :test do 
gem 'sqlite3', '1.3.8' 
gem 'rspec-rails', '2.13.1' 
# The following optional lines are part of the advanced setup. # gem ’guard-rspec’, ’2.5.0’

end 
gem 'sass-rails', '4.0.1' 
gem 'uglifier', '2.1.1' 
gem 'coffee-rails', '4.0.1'

gem 'sdoc', '0.3.20', require: false 
end 
group :production do 
gem 'pg', '0.15.1' 
gem 'rails_12factor', '0.0.2' 
end 

而且我user_spec.rb文件看起來像這樣：再次

require 'spec_helper' 

describe User do 

before do 
    { @user = User.new(name: "Example User", email: "user@example.com") } 
    end 

    subject { @user } 

    it { should respond_to(:name) } 
    it { should respond_to(:email) } 

    it { should be_valid } 

    describe "when name is not present" do 
    before { @user.name = " "} 
    it { should_not be_valid } 
    end 
end 

謝謝！

您傳遞給before的塊被do/end和花括號包圍。由於curlies不遵循方法調用，因此Ruby將它們解釋爲散列，並且在捲曲結束之前預期=>。只需刪除捲曲。
