If your master.key has been compromised, you might want to regenerate it.

No key regeneration feature at the moment. We have to do it manually.

Copy content of original credentials rails credentials:show somewhere temporarily.
Remove config/master.key and config/credentials.yml.enc
Run EDITOR=vim rails credentials:edit in the terminal: This command will create a new master.key and credentials.yml.enc if they do not exist.
Paste the original credentials you copied (step 1) in the new credentials file (and save + quit vim)
Add and Commit the file config/credentials.yml.enc

Debugger

	Since it is a second time that I spend 2 hours on the same problem I'll leave the solution here
	In case where you run the bundle exec rake db:create for the first time and get the error:
	$ "rake aborted!
	$ NoMethodError: undefined method 'name' in 'campsite' factory"

	The problem is the Deprecation of static attributes in factory_bot 4.11 and up.

	In your Gemfile you need to downgrade manually the factory_bot_rails from the latest version to something between 4.8.2 and 4.11
	For example it can be: gem 'factory_bot_rails', '~> 4.8.2'

	#Model

	@user.should have(1).error_on(:username) # Checks whether there is an error in username
	@user.errors[:username].should include("can't be blank") # check for the error message

	#Rendering
	response.should render_template(:index)

	#Redirecting
	response.should redirect_to(movies_path)

	#uninstall nokogiri:
	$ gem uninstall nokogiri

	#install nokogiri
	$ gem install nokogiri

	#restart terminal\if needed run gem pristine byebug --version 11.0.0
	#solved!

	FIXME:
	WARNING: Nokogiri was built against LibXML version 2.7.3, but has dynamically loaded 2.7.8
	or
	ERROR -: Incompatible library version: nokogiri.bundle requires version 11.0.0 or later, but libxml2.2.dylib provides version 10.0.0


	gem uninstall nokogiri libxml-ruby

	brew update
	brew uninstall libxml2

	$ rvm get stable

	# if there is a problem with getting the latest version run:

	$ rvm get head

	# if that does not work try:

	# On MAC OS High Sierra 10.13.6
	# You must recompile Ruby with OpenSSL error:

	$ rvm get head
	$ rvm pkg remove
	$ rvm requirements run
	# (I just ran the `rvm requirements` and it installed the missing parts.
	# I then reinstalled the newest version of Ruby and Rails, this worked for me.)
	$ rvm reinstall 2.6.0
