Guard with RSpec on Rails 4 giving a lot of warnings

ruby-on-rails ruby ruby-on-rails-4 rspec

I'm wondering how I can turn off all these warnings when running a simple test:

[1] guard(main)>

I'm running Rails 4.1.1, Ruby 2.1.2p95, and...

guard (2.6.1)
rspec (3.0.0)
guard-rspec (4.2.9)

I've tried running guard with:

guard :rspec, cmd:"ruby -W0 bin/rspec" do

instead of:

guard :rspec, cmd:"spring rspec" do

But it didn't do anything.

These warnings are super annoying, and I'm pretty sure I'm not causing them. Help!

It might be because you are running a pretty new version of ruby. One of the gems might not fully support it yet.

I ruled that out by running it on 1.9.3. Same warnings.

As implied in the accepted answer, this does not have anything to do with using Guard.

The rspec generator rails generate rspec:install now puts the --warnings option in the .rspec file by default. Remove that line, and the warnings will go away.

That will remove all warnings right? What if you only want to remove warnings from gems? I'd like to see warnings from my own code.

The --warnings option turns on or off warnings at the ruby level, and removing the option essentially keeps the default ruby and rails behavior. The answer to this question is not straightforward and deserves to be asked as a separate StackOverflow question.

e.g. see: stackoverflow.com/questions/5591509/…

You can set the warnings to false in the your test environment to force Rspec to disable the warnings messages.

# spec/spec_helper.rb

config.warnings = false
