I am new to rails.


After I setup env :
1. created first project with command rails new firstrail
2. Enter demo directory
3. run command rails server
 


Here, I got the error :

uglifier 2.7.2 was installed. I don't know how to fix this error.
Does any know how to fix this ?
Please help me out, thank you !
 
Do you see any errors if you run
bundle install
It should not have been necessary to run it manually as it is run automatically when you do rails new, but perhaps there was an error that you did not notice.  It is necessary to re-run bundle if you change Gemfile.

Otherwise then post the details of the error when you run the server please.  Copy/paste the full terminal output that you get when you run
rails s
