[英]Bundler could not find compatible versions for gem, updating Rails app
After createing a brand new rails app Following the official rails blog post , attempting to convert apps to rails 3.2.0.rc2 yields the following 创建一个全新的rails应用程序之后在官方rails博客文章后 ,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

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

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)
What exactly is the issue? 究竟是什么问题?
Mac OS 10.7.2, Xcode 4.2.1, rvm 1.10.1 using ruby 1.9.3p0 (2011-10-30 revision 33570) [x86_64-darwin11.2.0] 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]
I solved it by deleting the lock rm Gemfile.lock
and again running bundle install
: 我通过删除锁
rm Gemfile.lock
并再次运行bundle install

$ rm Gemfile.lock

Your bundle is complete! Use `bundle show [gemname]` to see where a bundled gem is installed.
This is a pretty brute force way of fixing the issue. 这是解决问题的一种非常强力的方法。 If this is an established project, you may run into other issues after deleting the
Gemfile.lock
as the dependency versions are no longer locked. 如果这是一个已建立的项目,则在删除
Gemfile.lock
后可能会遇到其他问题,因为依赖项版本不再被锁定。 However, if this is a new project it's unlikely you will run into problems taking this approach. 但是,如果这是一个新项目,那么采用这种方法就不会遇到问题。
除了sass-rails
,你还需要碰到你所依赖的coffee-rails
版本(3.2.1应该这样做)
如果您的Bundler版本与Gemfile.lock的最后一行中的BUNDLED WITH不同,则只有在向Gemfile添加新gem之后才会出现'找不到gem GEMNAME的兼容版本'。
go like this: gem 'activeadmin', github: 'gregbell/active_admin'
in da gemfile. 像这样:
gem 'activeadmin', github: 'gregbell/active_admin'
da gemfile中的gem 'activeadmin', github: 'gregbell/active_admin'
。 Active admin support for rails 4 merged into master branch Active admin install with Rails 4 rails 4的主动管理支持合并到主分支使用Rails 4的主动管理安装
