+bundle install --path vendor/bundle
The dependency tzinfo-data (>= 0) will be unused by any of the platforms Bundler is installing for. Bundler is installing for ruby but the dependency is only for x86-mingw32, x64-mingw32, x86-mswin32. To add those platforms to the bundle, run `bundle lock --add-platform x86-mingw32 x64-mingw32 x86-mswin32`.

Resolving dependencies...
Bundler could not find compatible versions for gem "bundler":
In Gemfile:
rails (= 4.2.11) was resolved to 4.2.11, 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
(= 4.2.11)', in any of the sources.
