Rails Debugger won't let me start the rails server

I have installed Ruby 2.3.0 and Rails 4.2.6 and Byebug,as I found out that Debugger Inspector won't work with versions over 2.0.Everything worked just fine for a while,but then I had to restart my laptop because of an Ubuntu crash.Now,whenever I try to start my server again,this error will appear ~/blog$ bin/rails server Could not find rails-dom-testing-1.0.7 in any of the sources Run bundle install to install missing gems. But..when I try to install bundle AGAIN Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

Make sure that gem install debug_inspector -v '0.0.2' succeeds before bundling.

What should I do? Thanks.
