Q:

Rails Server Launch Fail

I need help to fix my ruby. It was working perfectly fine until this morning when I tried to start up my rails server and I've received this error msg:

Daniels-MacBook-Pro:myrubyblog daniellim$ rails s -p 5040 /Users/daniellim/.rbenv/versions/2.3.0/bin/rails:23:in load': cannot load such file -- /Users/daniellim/.rbenv/versions/2.3.0/lib/ruby/gems/2.3.0/gems/rails-4.2.6/bin/rails (LoadError)     from /Users/daniellim/.rbenv/versions/2.3.0/bin/rails:23:in main>'

I have tried bundle install and update but it doesn't seem to be working.

A:

According to the error you are getting which is you don't have the rails (or right version of rails) installed.
Therefore, first install rails on your system 
gem install rails -v 4.2.6

Or if you already have it installed, update it
gem update rails 

Tell me if I am missing on something?
