My problem is very common in Ruby and Rails. Though I went through different stackoverflow answers, I could not find anything specific which would fix my error.

I tried reinstalling lower version of the railites gem but the same error keeps popping. I tried reinstalling all the gems that were throwing errors and still the problem doesnt seem to go away. Many articles indicated that this is a compatibility issue. But when I tried reinstalling a lower version of the railties gem(4.0.0), the command prompt still asked me to upgrade to the latest version in order to continue. I also installed 'Passenger' web server to check the compatibility and a similar error popped up but this time with the passenger gem. Please look into this accordingly. I am also copying below the gem file.
