Click on this text:

and then press Right Alt + Enter (shortcut for quick fixes) -> Select the first suggestion which should state something like Change version to...25.x.x.

This will ensure that you will be using the newest version.

As indicated in the error message, the problem is with the AppCompat support library, not the ConstraintLayout library. Specify a particular version or add an * after the major version code, like so:

compile 'com.android.support:appcompat-v7:25.3.1'

or

compile 'com.android.support:appcompat-v7:25.*'
