I am trying to set up my local environment for a particular repository when I came across this error.
An error occurred while installing mini_racer (0.1.15), and Bundler cannot continue.
Make sure that `gem install mini_racer -v '0.1.15' --source 'https://rubygems.org/'` succeeds before bundling.
My local machine is a macOS X (Mojave). I installed ruby 2.1.5, updated the bundler and ran bundle install
This is the error in detail:-

I researched the problem based on a relevant link: https://github.com/discourse/mini_racer/issues/104
and based on a couple of stack overflow posts, I uninstalled the libv8 gem and then tried to gem install mini_racer. Unfortunately, it did not work
Even reinstalling ruby again did not have any effect. How can I resolve this problem?
This stack overflow post is for a problem similar to minesimilar post, and it says that setting up a different version is probably the best, not quite sure which is the best version for ruby (2.1.5) and rails (3.2.xx)
