Hi

I am very new to ruby. I have created a sample project using rails and installed an ibm\_db driver.

I ran this command (rails g model employee name:string email:string).  
everything is fine till now and after running this command ‘rake db:migrate’  
I am facing :  
rake aborted!  
NoMethodError: undefined method `supports\_datetime\_with\_precision?’ for “ar\_internal\_metadata”:String

I am using ruby 2.6.5, rails 6.0.1

Thanks,  
Akhil
