问题
My rails project works just fine. But rubymine highlights error expected ; or end of line after some colon :. For example
before_action :set_answer, only: [:show, :edit, :update, :destroy]
format.html { redirect_to @answer, notice: 'Answer was successfully created.' }
In above rubymine highlights error after only: and notice:. But it doesn't highlight error after :set_answer, :show, :edit, :update or :destroy.
What is the reason for this and How can I fix this?
回答1:
With later RubyMine versions on Mac: Go to Preferences -> 'Language & Frameworks' -> 'Ruby SDK and Gems', and change to Ruby 2.0 SDK Restart and it should work.
