Question

我有以下Rakefile：

require File.expand_path('../config/application', __FILE__)
A4aa2::Application.load_tasks

if defined? RSpec
  task(:default).clear
  task default: :'spec:fuubar'

  namespace :spec do
    desc 'Run all specs in spec directory (with Fuubar formatter)'
    RSpec::Core::RakeTask.new(:fuubar) do |task|
      task.rspec_opts = [task.rspec_opts.to_s, '--color --format Fuubar'].compact.join ' '
    end
  end
end

我明确核对if defined? RSpec，但这并不能防止以下错误：

rake db:seed RAILS_ENV=production --trace
rake aborted!

我是否还必须检查是否已定义RSpec::Core？并且whay在生产环境中定义为RSpec吗？

我的Gemfile看起来像这样：

group :development, :test do  
  gem 'rspec'
  gem 'rspec-rails' # RSpec for Rails

我不想将RSpec放入:production组，这就是我检查RSpec是否在Rakefile中定义的原因}，但似乎在RSpec中定义了:production （虽然我只在:development和:test组中加载它），虽然RSpec::Core不是。

Answer 1

确保Beautiful Soup位于read = [urllib.urlopen(link).read() for link in article_links] data = [BeautifulSoup(i).find('title').getText() for i in read]的{{1}}群组内。

rspec在gem rspec组之外：

:test

在Gemfile组内使用rspec：

:test

Answer 2

通过检查适当的环境，例如，您可以完全避免此问题。 unless Rails.env.production?

想要使用RAILS_ENV = production进行播种，但获取NameError：未初始化的常量RSpec :: Core
