undefined method `first' for nil:NilClass (NoMethodError)

[giacomo-giovenzana]

When I run "rails console" I get the following error: $ rails c /usr/lib/ruby/vendor_ruby/sprockets/digest_utils.rb:47: warning: constant ::Fixnum is deprecated /usr/lib/ruby/vendor_ruby/sprockets/digest_utils.rb:51: warning: constant ::Bignum is deprecated /usr/lib/ruby/vendor_ruby/sprockets/processor_utils.rb:110: warning: constant ::Fixnum is deprecated /usr/lib/ruby/vendor_ruby/sprockets/processor_utils.rb:111: warning: constant ::Bignum is deprecated /usr/lib/ruby/vendor_ruby/builder/xchar.rb:111: warning: constant ::Fixnum is deprecated Traceback (most recent call last): -e: undefined method first' for nil:NilClass (NoMethodError)`

I have tried to restart spring by bin/spring stop or by a kill -9 command on pid.

Then, trying to re-run the same command I get the following: $ rails c ^CTraceback (most recent call last): 16: from bin/rails:3:in

Rails command remains hanged and no message is shown. When I press Ctrl+C I get this error.

I have already tryed to uninstall and install spring but it does not solve.

I am using rails 5.1.1 and ruby 2.5.1. I have googled the issue but I didn't find any useful solution. Honestly, I don't know if it could be an issue of spring.
