My OS X version is OS X EI captain so I was follow this instruction To disable System Integrity Protection to solve this problem:

  1.   Boot into the Recovery HD by restarting whilst holding ⌘R.
  2.   Open Terminal (from the Utilities menu).
  3.   Run the following command in Terminal: csrutil disable
