Q&A前提・実現したいこと
Ruby on Railsを5.2.4から5.2.8にアップグレードして無事にアプリケーションは起動できるようになり、bundle exec rails db:migrateなどのコマンドも実行できます。
しかし、bundle exec rspec のコマンドでRSpecを実行すると以下のようなエラーが発生してRSpecが実行されません。
どのように対応すれば、RSpecは動くでしょうか？

以下の記事を参考にして、Gemfileにgem 'psych', '~> 3.1'を追加しbundle installすると今度は以下のようなエラーになってしまいます。
% bundle install Warning: the running version of Bundler (1.17.2) is older than the version that created the lockfile (1.17.3). We suggest you upgrade to the latest version of Bundler by running `gem install bundler`. Fetching gem metadata from https://rubygems.org/......... Fetching gem metadata from https://rubygems.org/. You have requested: psych ~> 3.1 The bundle currently has psych locked at 4.0.4. Try running `bundle update psych` If you are updating multiple gems in your Gemfile at once, try passing them all to `bundle update`

また、RSpecのバージョンは以下のようになっております。（バージョンアップする前は、rspec-rails (4.0.0)でした。）
Gemfile.lock rspec-core (3.11.0) rspec-support (~> 3.11.0) rspec-expectations (3.11.0) diff-lcs (>= 1.2.0, < 2.0) rspec-support (~> 3.11.0) rspec-mocks (3.11.1) diff-lcs (>= 1.2.0, < 2.0) rspec-support (~> 3.11.0) rspec-rails (5.1.2) actionpack (>= 5.2) activesupport (>= 5.2) railties (>= 5.2) rspec-core (~> 3.10) rspec-expectations (~> 3.10) rspec-mocks (~> 3.10) rspec-support (~> 3.10) rspec-support (3.11.0)
エラーが発生しているファイルは以下となります。
Rails_helper.rb ENV['RAILS_ENV'] ||= 'test' require File.expand_path('../../config/environment', __FILE__) abort("The Rails environment is running in production mode!") if Rails.env.production? require 'spec_helper' require 'rspec/rails' require 'shoulda/matchers' Shoulda::Matchers.configure do |config| config.integrate do |with| with.test_framework :rspec with.library :active_record with.library :active_model with.library :action_controller with.library :rails end end # Coverage require 'simplecov' SimpleCov.start 'rails' ActiveRecord::Migration.maintain_test_schema!

お手数をお掛けいたしますが、よろしくお願いいたします。
