Searcher Gem 和 ActiveRecord

Question

如果我在我的 Gemfile 中使用：

gem "searcher", github: "radar/searcher"

捆绑安装完美运行。但我正在尝试为 heroku 部署，但我遇到了这个错误：

$ git push heroku master

    error: failed to push some refs to 'https://git.heroku.com/glacial-beyond-39560.git'

然后我尝试在 Gemfile 中调整以仅放置 gem "searcher"，但尝试捆绑时出现错误：

   Bundler could not find compatible versions for gem "activerecord":
  In snapshot (Gemfile.lock):
    activerecord (= 4.2.1)

  In Gemfile:
    rails (= 4.2.1) was resolved to 4.2.1, which depends on
      activerecord (= 4.2.1)

    searcher was resolved to 0.0.1, which depends on
      activerecord (~> 3.0.0)

Running `bundle update` will rebuild your snapshot from scratch, using only
the gems in your Gemfile, which may resolve the conflict.

我看到建议使用 ActiveRecord 3x。我需要做什么（为active_record 3x安装一个版本的rails？或者我厚的是这个gem的安全协议？有人可以帮我吗？？？

Answer 1

在尝试了很多方法后我成功改变了：

gem "searcher", github: "radar/searcher"

为此：

gem "searcher", git: "https://github.com/radar/searcher.git"

Answer 2

我想删除 Gemfile.lock 的内容，然后再次运行 bundle install。这对我有用。
