Your Gemfile lists the gem byebug (>= 0) more than once.
You should probably keep only one of them.
Remove any duplicate entries and specify the gem only once.
While it's not a problem now, it could cause errors if you change the version of one of them later.
Resolving dependencies...
Bundler could not find compatible versions for gem "bundler":
In Gemfile:
rails (= 4.2.11.1) was resolved to 4.2.11.1, which depends on
bundler (>= 1.3.0, < 2.0)
Current Bundler version:
bundler (2.1.4)
This Gemfile requires a different version of Bundler.
Perhaps you need to update Bundler by running `gem install bundler`?
Could not find gem 'bundler (>= 1.3.0, < 2.0)', which is required by gem 'rails (= 4.2.11.1)', in any of the sources.
您具有Bundler 2.1.4，并且Rails 4.2不适用于Bundler 2及更高版本。
您需要安装受支持的捆绑软件版本，如下所示：
gem install bundler:1.17.3
