我先改变我的Gemfile(我删除了评论,使文本更短)：
source 'https://rubygems.org' gem 'rails','4.2.0' gem 'sqlite3' gem 'sass-rails','~> 5.0' gem 'uglifier','>= 1.3.0' gem 'coffee-rails','~> 4.1.0' gem 'jquery-rails' gem 'turbolinks' gem 'jbuilder','~> 2.0' gem 'sdoc','~> 0.4.0',group: :doc group :development,:test do gem 'byebug' gem 'web-console','~> 2.0' gem 'spring' end
至：
source 'https://rubygems.org' gem 'rails','4.2.0' gem 'sass-rails','5.0.1' gem 'uglifier','2.5.3' gem 'coffee-rails','4.1.0' gem 'jquery-rails','4.0.3' gem 'turbolinks','2.3.0' gem 'jbuilder','2.2.3' gem 'sdoc','0.4.0',group: :doc group :development,:test do gem 'sqlite3','1.3.9' gem 'byebug','3.4.0' gem 'web-console','2.0.0.beta3' gem 'spring','1.1.3' end
现在当我尝试运行rails服务器与rails server -b $IP -p $PORT我得到以下错误消息：

在更改Gemfile之前,我尝试运行服务器,它的工作原理是因为新的更改.另外我知道这个错误说ruby-2.1.5,而在我的Gemfile中,我放了4.2.0,但是我不知道如何改变这个,还是这个问题呢？我试图在源代码行下添加ruby“2.1.5”,没有改变.此外,我将“rails”,“4.2.0”更改为2.1.5,但更新失败,告诉我在本机上可用的宝石中找不到gem’rails(= 2.1.5)ruby’.
解决方法
如此说：
https://github.com/josh/sprockets-es6/issues/15
使用sass-rails v 5.0.2.这应该可以解决你的问题.所以在宝石文件中更改：
gem 'sass-rails','5.0.3'
要么
gem 'sass-rails','5.0.2'
更新：
由于链接现在已经下了,所以这个问题实际上是与宝石版本5.0.1所以只是运行：
bundle update sass-rails
最终将saas-rails gem更新到最新版本.或者您可以在上面指定的gemfile中输入版本.
