Why does my rails not run?

Question

When I run $ rails -server to start a server, there comes an error:

Could not find gem 'sqlite3' in any of the gem sources listed in your Gemfile or available on this machine.

Does that mean I did not install sqlite3? How can I resolve the issue?

First, you have to install all Gems from your Gemfile.

This can be done with bundle install or in short bundle.

If this command executed successfully, you can run your server with rails s.

But I think it's better for you, to start with a tutorial.

server and s are not a switch, but a sub-command.

Run

$ rails server

or

$ rails s

I run into this issue previously， that is because you run bundle install, miss some gems, so you can $ bundle install again,

and you can test the sqlite if is installed:

$ sqlite3 --version

If successed, you can test the rails server.
