Question

我的Rails应用程序是4.2.7，我更新到5.1.4。当我更改Gemfile时： gem 'rails', '5.1.4'然后运行bundle update rails，我收到此错误：

Bundler could not find compatible versions for gem "rack":
  In Gemfile:
    rails (= 5.1.4) was resolved to 5.1.4, which depends on
      actionpack (= 5.1.4) was resolved to 5.1.4, which depends on
        rack (~> 2.0)

    mailcatcher was resolved to 0.6.5, which depends on
      rack (~> 1.5)

我检查了rack releases，但我不知道如何处理这些信息。我该如何解决这个问题？

我只是粘贴整个Gemfile，所以我不会错过任何内容：

Answer 1

删除Gemfile.lock然后bundle update解决了这个问题。

更新到Rails 5.1.4：Bundler找不到gem＆＃34; rack＆＃34;的兼容版本。
