Hi colin, I tried what you said, It reinstalled the ruby then rails, but when it downloaded the nokogiri1.6.7.0.gem, it showed error. But anyway rails was installed. When i checked the version it shows ~$ rails -v Ignoring executable-hooks-1.3.2 because its extensions are not built. Try: gem pristine executable-hooks --version 1.3.2 Ignoring gem-wrappers-1.2.7 because its extensions are not built. Try: gem pristine gem-wrappers --version 1.2.7 Ignoring nokogiri-1.6.7.1 because its extensions are not built. Try: gem pristine nokogiri --version 1.6.7.1 Rails 4.2.5
