You've tried to invoke Spring when it's already loaded (i.e. the Spring constant is defined)

This is probably because you generated binstubs with Spring 1.0, and you now have a Spring version > 1.0 on your system. To solve this, upgrade your bundle to the latest Spring version and then run bundle exec spring binstub --all to regenerate your binstubs. This is a one-time step necessary to upgrade from 1.0 to 1.1.

Here's the backtrace:

/Users/m/Image-Classifier/vendor/bundle/ruby/2.7.0/gems/spring-2.1.1/lib/spring/binstub.rb:11:in load' /Users/m/Image-Classifier/vendor/bundle/ruby/2.7.0/gems/spring-2.1.1/lib/spring/binstub.rb:11:in <top (required)>' /Users/m/.rvm/rubies/ruby-2.7.1/lib/ruby/2.7.0/rubygems/core_ext/kernel_require.rb:92:in require' /Users/m/.rvm/rubies/ruby-2.7.1/lib/ruby/2.7.0/rubygems/core_ext/kernel_require.rb:92:in require' /Users/m/Image-Classifier/bin/spring:15:in <top (required)>' /Users/m/Image-Classifier/bin/rails:3:in load' /Users/m/Image-Classifier/bin/rails:3:in `'

I try with Spring and middleware conflict? but don't worked
