Unable to install PHPUnit_Invoker on Windows 7

pear, php, phpunit

Solution

The PHP extension “PCNTL” (Process Control), required by PHP_Invoker, currently does not function on non-Unix platforms (Windows).

Problem

I am trying to install PHPUnit_Invoker. I run the command `pear install phpunit/PHP_Invoker` on the command line. I am getting this message: No releases available for package "pear.phpunit.de/PHP_Invoker" I have already installed PHPUnit and PEAR on a Windows machine. Is anybody also facing similar problem? I tried again and I get this message in console: phpunit/PHP_Invoker requires PHP extension "pcntl" No valid packages found install failed
