On your local environment (not in the IDE), run shotgun to start a local server so that you can test your app in your browser. Shotgun default is using port 9393, you should be able to visit the following url http://localhost:9393.

Alterations to Gemfile.lock could be necessary.

I could not install the gems, and with help from a technical coach and another student (who experienced the same issue) found that I could not install the gems unless I deleted the Gemfile.lock.

This is the error I was getting:

The file "/usr/include/iconv.h" is missing in your build environment,
which means you haven't installed Xcode Command Line Tools properly.

To install Command Line Tools, try running `xcode-select --install` on
terminal and follow the instructions.  If it fails, open Xcode.app,
select from the menu "Xcode" - "Open Developer Tool" - "More Developer
Tools" to open the developer site, download the installer for your OS
version and run it.

An error occurred while installing nokogiri (1.6.6.2), and Bundler
cannot continue.
Make sure that `gem install nokogiri -v '1.6.6.2' --source
'https://rubygems.org/'` succeeds before bundling.

In Gemfile:
  capybara was resolved to 2.4.4, which depends on
    xpath was resolved to 2.0.0, which depends on
      nokogiri``` 

I attempted to reinstall nokogiri, xcode, etc. individually and it didn't work until the Gemfile.lock was deleted.

Hope this is helpful.

i passed these tests locally and its not saying i did

Question on placement of this lab in Learn Qualifying track

Can this lab come after the Sinatra Basics readme? All the information covered in the readmes after this one aren't needed to complete this lab. It would also be helpful to have more labs in this unit since there is a ton of info presented but not very much practice for the student.

Or if not labs, quizzes would be helpful too.

cc @matbalez

Initial Lab

Make into a lab.

http://localhost:9393 and the IDE

When working in the IDE, visiting http://localhost:9393 to test your web app wont work.
Please add a note, because it can get a little confusing.
