Error on installing

[user1007017]

If I try to install it with composer require --prefer-dist p2made/yii2-startbootstrap-themes "^2.16"

I'm getting the following error:

Installation failed, reverting ./composer.json to its original content.

  [UnexpectedValueException]  
  Could not parse version     
  constraint >=~2: Invalid    
  version string "~2"

Facing similar issue. I am getting the following error when trying to install using composer require --prefer-dist p2made/yii2-startbootstrap-themes "^2.16".

Installation failed, reverting ./composer.json to its original content.

[Composer\Repository\InvalidRepositoryException] No valid bower.json was found in any branch or tag of https://github.com/Dm itryBaranovskiy/eve.git, could not load a package from it.

Any solutions?

Below is my composer.json file
