Cannot Install

[dudunegrinhu]

I'm getting this error:

Your requirements could not be resolved to an installable set of packages.

Problem 1
- Installation request for mycademy/yii2-bootstrap-tour dev-master -> satisfiable by mycademy/yii2-bootstrap-tour[dev-master].
- mycademy/yii2-bootstrap-tour dev-master requires sorich87/bootstrap-tour dev-master -> 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 minimum-stability setting

I'm getting the same error. Any news on this?
