在遵循rails官方博客post创建了一个全新的rails应用程序后,尝试将应用程序转换为rails 3.2.0.rc2会产生以下结果
Updated Gemfile to depend on rails ~> 3.2.0.rc2
gem 'rails', '~>3.2.0.rc2'
Updated Gemfile to depend on sass-rails ~> 3.2.3
gem 'sass-rails', '~> 3.2.3'
$ bundle install
Fetching source index for http://rubygems.org/
Bundler could not find compatible versions for gem "activesupport":
In snapshot (Gemfile.lock):
activesupport (3.1.1)
In Gemfile:
rails (~> 3.2.0.rc2) ruby depends on
activesupport (= 3.2.0.rc2) ruby
Running `bundle update` will rebuild your snapshot from scratch, using
only the gems in your Gemfile, which may resolve the conflict.
$bundle update
Fetching source index for http://rubygems.org/
Bundler could not find compatible versions for gem "railties":
In Gemfile:
coffee-rails (~> 3.1.1) ruby depends on
railties (~> 3.1.0) ruby
rails (~> 3.2.0.rc2) ruby depends on
railties (3.2.0.rc2)
到底是什么问题呢?
系统规格:
Mac OS 10.7.2,Xcode 4.2.1,rvm 1.10.1,使用ruby 1.9.3p0 (2011-10-30修订版33570) x86_64-darwin11.2.0

并再次运行bundle install

Your bundle is complete! Use `bundle show [gemname]` to see where a bundled gem is installed.
这是一种非常暴力的解决问题的方法。如果这是一个已建立的项目,删除Gemfile.lock
后可能会遇到其他问题,因为依赖版本不再被锁定。但是,如果这是一个新项目,采用这种方法不太可能遇到问题。

除了sass-rails
,你还需要升级你所依赖的coffee-rails
版本(3.2.1应该可以做到)

如果您的捆绑包版本与Gemfile.lock最后一行中捆绑的版本不同,则只有在将新gem添加到gem文件中之后,才会出现“找不到gem GEMNAME的兼容版本”的问题。
