ruby-on-rails - Bundler 找不到 gem "activesupport"的兼容版本

Question

我迁移到 3.2.13 版本的 rails 并收到此错误，我该如何摆脱这个错误？

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.

编辑

sinatra (1.3.6)
  rack (~> 1.4)
  rack-protection (~> 1.3)
  tilt (~> 1.3, >= 1.3.3)

Answer 1

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)；查看此帖子 Bundler could not find compatible versions for gem, updating Rails app

我的步骤被运行

gem update rails

rm Gemfile.lock

更改我的 Gemfile 以引用我想要的 rails 版本

gem 'rails', '3.2.13'

终于跑了

bundle install 

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。
