'invalid option: --format' when executing rspec

How do you run rspec files? From context menu, or you create run configuration manually?

From the context menu, but I've tried tweaking various options on the run configuration that gets created as a result without any luck.

Anyone have any ideas?  I've been unable to run my specs from within Intellij for close to a year now.

Mark, what IDEA and Ruby plugin versions do you have? In case you remove all existing Run configurations and launch "All specs in.." or a singe test, how does it go? In addition, how does it go from the command line (when launched manually)?

I am also experiencing this problem in RubyMine 2016.2.3 Build #RM-162.1812.23, built on September 5, 2016

I get the same results regardless of how I attempt to execute specs, whether as a single test or "All specs in...".  I have no problem running these specs from the command line, as long as I do not use the --format option

The output pasted below is similar to what was reported by Mark Schnitzius:

Hello, Michael,

could you please check how it goes in the last RubyMine 2016.3 EAP? If the problem persists would it possible to provide me with a sample project to reproduce the problem?

I've the latest version, still no luck

RubyMine 2022.1.3

Build #RM-221.5921.22, built on June 21, 2022

Hello! Can you please share a bit more context around the problem? Which version of Ruby are you using? Could you please share a project where we could reproduce it?

It happens when I use stripe-ruby-mock gem for some reason, 

Here is my `spec_helper.rb` file :

require 'require_all'
require 'helpers/authentication_helper'
require 'thin'
require 'stripe_mock'
require_all 'lib/core_extensions'

RSpec.configure do |config|
  config.include AuthenticationHelper
  StripeMock::Instance.include CoreExtensions::StripeMock::RequestHandlers::Invoices

  StripeMock.spawn_server
  config.expect_with :rspec do |expectations|

    expectations.include_chain_clauses_in_custom_matcher_descriptions = true
  end

  config.mock_with :rspec do |mocks|
    mocks.verify_partial_doubles = true
  end

  config.shared_context_metadata_behavior = :apply_to_host_groups
end

I'm getting this error when trying to run rspecs using RubyMine :

/bin/zsh -c "bash -c '/path/to/rvm ruby-2.7.1 do /path/to/rvm/rubies/ruby-2.7.1/bin/ruby -x /path/to/rvm/gems/ruby-2.7.1/bin/bundle exec /path/to/rvm/rubies/ruby-2.7.1/bin/ruby /path/to/rvm/gems/ruby-2.7.1/bin/rspec /path/to/project/spec/models/address_spec.rb --require teamcity/spec/runner/formatter/teamcity/formatter --format '\"'\"'Spec::Runner::Formatter::TeamcityFormatter'\"'\"' --example Address'"

It is working fine when I run directly on the terminal, I tried to solve the issue with no luck but it seems the error is somewhere in OptionParser#parse! , it seems caused because it's passing options to stripe-mock-server process where it doesn't expect any anguments, I'm not really sure, but I think that is part of the issue, I tried to fix by resetting the options when stripe-mock-server starts, so I made sure to pass empty options and it worked when I do tests with debug, but it doesn't work with normal run, here is how I make it work on debugging, I changed parse! method inside ruby lib itself, basically I reset the options when stripe-mock-server turn comes

def parse!(argv = default_argv, into: nil)
  @@cccc = 0 if !defined?(@@cccc)

  if @@cccc == 3
    7.times { argv.shift }
  else
    @@cccc += 1
  end

  if ENV.include?('POSIXLY_CORRECT')
    order!(argv, into: into)
  else
    permute!(argv, into: into)
  end
end

Oleg Olkhovoy  I believe this github issue is pretty much related will also help, this hack worked for me, but it doesn't feel like a sustainable solution
