问题
When I could run the rails project yesterday on local.
But today I can't run the project with the below issues.
I haven't done anything. I am using Spring 2.1.0
$ rails s
=> Booting Puma
=> Rails 5.2.4.1 application starting in development
=> Run `rails server -h` for more startup options
Exiting
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:

I know this issue is a commonly known issue.
I have researched to fix issues but I couldn't fix it.
Anyone had this issue before?
