我正在尝试在我的rails应用程序上设置/运行rspec测试，但不断收到此错误：
Missing helper file helpers//users/myname/desktop/the_odin_project/myapp/app/helpers/application_helper.rb_helper.rb (AbstractController::Helpers::MissingHelperError)
我一整天都在尝试解决这个问题，但无济于事。大多数回复都说这是你路上某个地方错位的大写字母，但这并没有奏效。我无法弄清楚为什么它不起作用。

# This option will default to `true` in RSpec 4. It makes the `description`

# defined using `chain`, e.g.:
# be_bigger_than(2).and_smaller_than(4).description
# # => "be bigger than 2 and smaller than 4"

# rspec-mocks config goes here. You can use an alternate test double
# library (such as bogus or mocha) by changing the `mock_with` option here.
config.mock_with :rspec do |mocks|
# Prevents you from mocking or stubbing a method that does not exist on
# a real object. This is generally recommended, and will default to
# `true` in RSpec 4.

end
# This option will default to `:apply_to_host_groups` in RSpec 4 (and will
# have no way to turn it off -- the option exists only for backwards
# compatibility in RSpec 3). It causes shared context metadata to be
# inherited by the metadata hash of host groups and examples, rather than
# triggering implicit auto-inclusion in groups with matching metadata.
