保護意外的tIdentifier錯誤

Question

我是新來編碼，並希望我遵循所有的規則相應發佈此問題。

我正在經歷一個Ruby on Rails的介紹，在我的一個示例中，GUARD運行時我收到以下'Unexpect tIDENTIFIER'消息，我似乎無法找出原因。

ERROR["test_should_get_about", StaticPagesControllerTest, 0.012288] 
test_should_get_about#StaticPagesControllerTest (0.01s) 
SyntaxError:   SyntaxError: /Users/NateFeder/_projectbox/rails-tutorial/sample_app/app/controllers/static_pages_controller.rb:12: syntax error, unexpected tIDENTIFIER, expecting keyword_do or '{' or '(' 
    About |Ruby on Rails Tutorial Sample App 
       ^
ERROR["test_should_get_home", StaticPagesControllerTest, 0.004128]

SyntaxError:   SyntaxError: /Users/NateFeder/_projectbox/rails-tutorial/sample_app/app/controllers/static_pages_controller.rb:12: syntax error, unexpected tIDENTIFIER, expecting keyword_do or '{' or '('

ERROR["test_should_get_help", StaticPagesControllerTest, 0.008452]

    About |Ruby on Rails Tutorial Sample App 

我StaticPagesControllerTest低於：

require 'test_helper' 

class StaticPagesControllerTest < ActionController::TestCase 

test "should get home" do 
get :home 
assert_response :success 
assert_select "title", 'Home | Ruby on Rails Tutorial Sample App' 
end 

test "should get help" do 
get :help 
assert_response :success 
assert_select "title", 'Help | Ruby on Rails Tutorial Sample App' 

end 

test "should get about" do 
get :about 
assert_response :success 
assert_select 'title", "About | Ruby on Rails Tutorial Sample App' 

end 

end 

感謝

Answer 1

你的錯誤是，你使用的不一致單VS雙引號：

test "should get about" do 
get :about 
assert_response :success 
assert_select 'title", "About | Ruby on Rails Tutorial Sample App' 
# ------------^ here 

end 

這是比較主觀的，但爲了避免這種錯誤，選擇一個（單或雙）和stic可能是一個好主意k去它，除非你必須使用別的東西（即做#{}字符串插值）

回去後，我意識到我有一個額外的layout_file。我刪除了額外的文件，錯誤消失了。活泉！

經驗教訓。
