RedClothのGemがを使用するとRailsサーバが立ち上がらない

タイトルの通りです。

Gemfile
1source 'http://rubygems.org'
2
3gem 'rails', '5.2.0'
4
5# Bundle edge Rails instead:
6# gem 'rails', :git => 'git://github.com/rails/rails.git'
7
8gem 'RedCloth', '4.2.3'

上記のようにRedCloth4.2.3をRails5.2.0でinstallするとbundle exec rails sした際にエラーが出ます。
bundlerは2.0.2です。
