I installed rails in windows, is there a command to know what is the version of app server installed in in my rails? What is command?
The version of rails is specified in the gemfile
When you say rails new my_app , it generates an entire project(app, log, config, db etc). A gemfile would also be generate . If you open the gemfile you will be able to find the version of your rails.
You will find something like gem rails , '3.2.1'
