ruby-on-rails – Rspec / Rails：未初始化的常量ActiveSupport :: Autoload(NameError)

我试图运行bundle exec rspec但是我在调​​用spec_helper.rb时遇到了以下错误

template.rb:8:in `<class:Template>': uninitialized constant ActiveSupport::Autoload (NameError)

这是我的spec_helper.rb文件：

require 'rubygems'
require 'rspec/rails'
ENV["RAILS_ENV"] ||= 'test'
require File.expand_path("../../config/environment",__FILE__)   
RSpec.configure do |config|
  config.infer_spec_type_from_file_location!
end

解决方法

在将我的Rspec文件的顺序切换到以下后,我不再获得未初始化的常量错误：

require File.expand_path("../../config/environment",__FILE__)
require 'rspec/rails'
require 'capybara/rspec'
require 'capybara/poltergeist'
Capybara.register_driver :poltergeist do |app|
  Capybara::Poltergeist::Driver.new(app,{:js_errors=> false})
end
RSpec.configure do |config|
  config.infer_spec_type_from_file_location!
