Hello,
i am using rails 5.2.
when ever i create a new app and run server, it is showing the following errors.

Puma caught this error: Error loading the 'sqlite3' Active Record adapter. Missing a gem it depends on? can't activate sqlite3 (~> 1.3.6), already activated sqlite3-1.4.0. Make sure all dependencies are added to Gemfile. (LoadError)

and to fix this i always have to install this
gem 'sqlite3', '~> 1.3.6'
to fix this issue.

how can i get the proper solution for this.
thank you.
