This is what my spec file looks like: spec/api/v1/projects_spec.rb

我的spec文件是这样的:spec/api/v1/projects_spec.rb

require "spec_helper"

describe "/api/v1/projects", :type => :api do
  context "projects viewable by this user" do
   it "JSON" do
   end
  end
end

It contained a lot more but I deleted a lot of lines in an unsuccessful attempt to find the error which goes like this:

它包含了更多，但我删除了很多行，试图找到错误如下:

Failure/Error: Unable to find matching line from backtrace
NoMethodError: undefined method `env' for nil:NilClass

This piece of code is from the "Rails 3 in Action" by Ryan Bigg. The only other file it includes is: spec/support/api/helper.rb

这段代码来自Ryan Bigg的“Rails 3 in Action”。它包含的其他文件是:spec/support/api/helper.rb

module ApiHelper
  include Rack::Test::Methods

  def app
   Rails.application
  end
end

RSpec.configure do |c|
  c.include ApiHelper, :type => :api
end

I've been trying to google the error for the past 1 hr and the closest thing that I found was this and as a result I deleted the code which used Devise::Test_Helpers. Sadly, its still not working.

我一直在尝试谷歌过去1小时的错误，我发现的最接近的是这个，结果我删除了设计:test_helper的代码。遗憾的是，它仍然不起作用。

Any help would be appreciated. Thank you so much.

如有任何帮助，我们将不胜感激。非常感谢。
