title: dependencies version error i cant change the version
body: <p>I'm trying to change the the version of my 'com.android.support:recyclerview'. Generally, when you want to change the version of android-support you have to change all the dependencies which are connected to com.android.support so I put the latest version which is 26.1.0 and it keeps giving me this error 
  please help me out </p>
