Resolving dependencies...
Bundler could not find compatible versions for gem "activesupport":
In snapshot (Gemfile.lock):
activesupport (3.2.12)
In Gemfile:
rails (= 3.2.13) ruby depends on
activesupport (= 3.2.13) ruby
Running `bundle update` will rebuild your snapshot from scratch, using only
the gems in your Gemfile, which may resolve the conflict.
EDIT
编辑
sinatra (1.3.6)
rack (~> 1.4)
rack-protection (~> 1.3)
tilt (~> 1.3, >= 1.3.3)

For anyone who accidently comes to this link (at the time google served this page first); check out this post Bundler could not find compatible versions for gem, updating Rails app
对于不小心访问此链接的任何人（当时谷歌首先提供此页面）；查看这篇文章Bundler 找不到 gem 的兼容版本，更新 Rails 应用程序
My steps were run
我的步骤被运行
gem update rails
rm Gemfile.lock
change my Gemfile to reference the version of rails i wanted
更改我的 Gemfile 以引用我想要的 rails 版本
gem 'rails', '3.2.13'
finally run
终于跑了
bundle install
I didn't try bundle update as @PistachioPony suggested but that might take the place of removing the lock file and rebuilding.
我没有像@PistachioPony 建议的那样尝试捆绑更新，但这可能会代替删除锁定文件并重建。

ActiveAdmin with Rails 4 requires you to track master. From the github page:
带有 Rails 4 的 ActiveAdmin 需要您跟踪 master。从github页面：
We're currently working on 1.0.0, which as far as dependencies, moves us from meta_search to Ransack and adds Rails 4 support. You can get Rails 4 and 4.1 support by tracking master:
我们目前正在开发 1.0.0，就依赖而言，它将我们从 meta_search 移动到 Ransack 并添加了 Rails 4 支持。您可以通过跟踪 master 获得 Rails 4 和 4.1 支持：
gem 'activeadmin', github: 'gregbell/active_admin'
gem 'activeadmin', github: 'gregbell/active_admin'
Also, make sure you DON'Tuse the docs on the main pagebecause they are outdated for rails 4. There are updated docs for rails 4with master.
另外，请确保您不要使用主页上的文档，因为它们对于 rails 4 来说已经过时了。有带有 master 的rails 4 的更新文档。
I'm not sure how much longer this answer will be relevant, so you should check githubto see if things have changed before blindly tracking master. Also, note that tracking master usually means you will get development changes as they come.
我不确定这个答案会持续多久，所以你应该在盲目跟踪 master 之前检查 github以查看情况是否发生了变化。另外，请注意，跟踪母版通常意味着您将在开发更改来临时获得它们。

If you changed your rails to 3.2.13 then also change your active support in the gemfile.lock to 3.2.13 then:
如果您将 rails 更改为 3.2.13，那么还将 gemfile.lock 中的活动支持更改为 3.2.13，然后：
Run:
跑：
$ bundle update
$ 捆绑更新
