Cannot install with composer

[pathros]

Hello, when I run the following command

$ composer require smithworx/text-miner

I get the following error:

"Could not find package smithworx/text-miner at any version for your minimum stability ... "

Then, if I try the following:

$ composer require smithworx/text-miner dev-master

I get another error:

"Your requirements could not be resolved to an installable set of packages. Problem 1 - The requested package smithworx/text-miner could not be found in any version, there may be a typo in the package name .... installation failed ...."

Any ideas to fix this so I can install it?
