Why is the package package not being installed from packagist.org?

Question

GitHub

I'm trying to install this package
https://packagist.org/packages/tsum/yii2-multipars...
or github
https://github.com/tsurkanovm/yii-multiparser
with the following command in the line
php composer.phar require "tsurkanovm/ yii-multiparser"
gives the following response

Could not find package tsurkanovm/yii-multiparser at any version for your minimum-stability (dev). Check the package spelling or your minimum-stability

why if composer.json has the same minimum-stability "dev" as the project?
Here is my composer.json
