I cannot reach http://localhost:3000 after starting Ruby on Rails
server when running Windows 8. After running rails server in the
directory that I want the server to start, the following prompt shows
up:

C:\Users\Brian\railsapp>rails server

C:\Users\Brian\railsapp>

After going to Internet Explorer 10, I tried to access http://localhost:3000,
and I got a "This page can't be displayed" error. I tried doing
"telnet localhost 3000" in the Command Prompt, and I got a "Could not
open connection to the host, on port 3000" error. I also tried
modifying C:\Windows\System32\drivers\etc\hosts, removing the # symbol
for one of the "localhost" entries, but I still could not access
http://localhost:3000. Please help me with this issue. Thank you.

The error is saying that it cannot find the sqlite3 adaptor. Have you run
bundle install

Since the server has exited that is not really surprising. Error
messages can be daunting but it is always worth reading them to try
and work out what the problem is.

According to the stack trace sqlite3 isn’t part of the bundle, so bundle install wouldn’t help without adding it first.

Also most rails devs use Linux or Mac for their work so I would advice the OP to use a VM with Ubuntu or set the machine up for dual boot. The chance to get help is much higher since he hasn’t to cope with windows specific errors for himself.

OK, I was not sure whether the error meant that it is not part of the
installed bundle or is missing from Gemfile itself, though I have to
admit that the error message is specific.

@CatGuy90 I would have expected sqlite to be included in Gemfile be
default, have you removed it yourself?
