Question

*在继续这个之前，我将更好地学习Rails 3.1。感谢大家的帮助：我学到了很多东西！ *

我正在尝试创建一个基于Gullery的在线产品组合，但我一开始就陷入困境：我无法创建数据库。当我运行'rake db：create'时，我收到以下错误：

rake aborted！

C：\ Sites \ gullery / RakeFile：14：语法错误，意外$ end，期待keyword_end

当我完整追踪时，我明白了：

C：\ Sites \ gullery＆gt; rake db：create --trace

rake aborted！

C：/ Sites / gullery / Rakefile：14：语法错误，意外$ end，期待keyword_e   ND

C：/RailsInstaller/Ruby1.9.2/bin/rake：19：in''

当我在Google上搜索“语法错误，意外的$ end，期待keyword_end”时，答案显示我错过了某个地方。不幸的是，我没有经验知道丢失了哪个文件。这是否是正确的问题？如果是这样，我应该在哪里看？如果没有，实际发生了什么？

我正在使用Ruby on Rails 3.0，Ruby 1.9.2和mySQL。

提前致谢！

编辑：C：\ Sites \ gullery \ Rakefile：

的内容

    # Add your own tasks in files placed in lib/tasks ending in .rake,
    # for example lib/tasks/switchtower.rake, and they will automatically be available to Rake.

    require(File.join(File.dirname(__FILE__), 'config', 'boot'))

    require 'rake'
    require 'rake/testtask'
    require 'rdoc/task'
    RDoc::Task.new do |rdoc|

    require 'tasks/rails'

    # Fail if unit tests fail
    task :default => [:test_units, :test_functional]

编辑2：在Rakefile中添加“end”消除了语法错误，但我仍无法使用数据库。

新的Rakefile：

# Add your own tasks in files placed in lib/tasks ending in .rake,
# for example lib/tasks/switchtower.rake, and they will automatically be available to Rake.

require(File.join(File.dirname(__FILE__), 'config', 'boot'))

require 'rake'
require 'rake/testtask'
require 'rdoc/task'
RDoc::Task.new do |rdoc|
end

require 'tasks/rails'

# Fail if unit tests fail
task :default => [:test_units, :test_functional]

新错误/追踪：

我正在运行Rails 3.1，我的Rakefile看起来像这样：

#!/usr/bin/env rake
# Add your own tasks in files placed in lib/tasks ending in .rake,
# for example lib/tasks/capistrano.rake, and they will automatically be available to Rake.

require File.expand_path('../config/application', __FILE__)

V0100::Application.load_tasks

V0100是我的应用程序名称，对应于您的“gullery”。
