Problem with installing the bundle

[chriszo111]

First of all, thanks for your time invested in this demo and tutorial. I kind of hope this woulnd't be dead (looking at latest commit date), but let's try.

I cloned the repository and tried running bundle install, but the versions are so old that it would not let me install anything.

❯ bundle install

Resolving dependencies...
Bundler could not find compatible versions for gem "bundler":
  In Gemfile:
    rails (= 4.2.5) was resolved to 4.2.5, which depends on
      bundler (< 2.0, >= 1.3.0)

  Current Bundler version:
    bundler (2.0.1)
This Gemfile requires a different version of Bundler.
Perhaps you need to update Bundler by running `gem install bundler`?

Could not find gem 'bundler (< 2.0, >= 1.3.0)', which is required by gem 'rails (= 4.2.5)', in any of the sources.

Bundler could not find compatible versions for gem "rails":
  In Gemfile:
    rails (= 4.2.5)

    react-rails (~> 1.5.0) was resolved to 1.5.0, which depends on
      rails (>= 3.2)

Bundler could not find compatible versions for gem "ruby":
  In Gemfile:
    ruby (~> 2.3.7.0)

    web-console was resolved to 4.0.0, which depends on
      ruby (>= 2.5)

I tried updating rails (to 5.2.2) but it only lead to a bunch of other errors of the same nature and I definitely didn't obtain that much knowledge yet, so I cannot fix them by myself. So before finding another outdated tutorial @gauravtiwari may be you have time to fix it :)
