New to rails stuck with rails server command

Question

i am new to ruby on rails, when i enter rails server command i get a strange message which i don't know how to deal with.

Using tzinfo-data 1.2015.7
Using uglifier 2.7.2
Using web-console 2.2.1
Bundle complete! 12 Gemfile dependencies, 53 gems now installed.
Use `bundle show [gemname]` to see where a bundled gem is installed.

If someone with more experience could just point me in the right direction, I would greatly appreciate it. I have been working on this install for days!

Answer 1

It looks like you have nokogiri installed but for the wrong version of ruby. It's installed for ruby 2.2.0 but you're using ruby 2.2.3.

add these two files:

.ruby-gemset

rails4.2.4

.ruby-version

ruby-2.2.3

Then run:

bundle install
