Install error!

[dungphanxuan]

Hello, i install package and receive error! Your requirements could not be resolved to an installable set of packages.

Problem 1

• Installation request for kartik-v/yii2-markdown dev-master -> satisfiable by kartik-v/yii2-markdown[dev-master].
• kartik-v/yii2-markdown dev-master requires michelf/php-smartypants * -> no matching package found.

Potential causes:

• A typo in the package name
• The package is not available in a stable-enough version according to your min imum-stability setting see https://groups.google.com/d/topic/composer-dev/_g3ASeIFlrc/discussion f or more details.

Read http://getcomposer.org/doc/articles/troubleshooting.md for further common problems.

you need to study more about managing this within your composer settings in your application's composer.json file... for example the michelf/php-smartypants dependency is not getting installed on your environment... you need to check that...

One way for example is to set your minimum-stability to dev in your composer json...
