i cant programme attiny85 with Arduino 1.8.7 ide?
Correct, the default configuration does not include the atTiny devices. You add the cores to the IDE using the boards manager.
Follow the instructions here: ATTinyCore/Installation.md at OldMaster---DO-NOT-SUBMIT-PRs-here-Use-2.0.0-dev · SpenceKonde/ATTinyCore · GitHub
Perhaps you should stick with the last IDE you could use. ...
