无法更新到轨4.1：从轨更新从4.0到4.1 simple_form

Question

冲突，我偶然在以下依赖问题：

Fetching additional metadata from https://rubygems.org/.. 
Resolving dependencies... 
Bundler could not find compatible versions for gem "activemodel": 
    In Gemfile: 
    simple_form (>= 0) ruby depends on 
     activemodel (< 4.1, >= 4.0.0) ruby 

    rails (= 4.1.0) ruby depends on 
     activemodel (4.1.0) 

如何安装rails 4.1与simple_form？

Answer 1

您需要使用github版本，因为rubygems似乎不起作用。 在您的Gemfile，更新simple_form到：

gem 'simple_form', github: 'plataformatec/simple_form'
