Bundler 找不到 gem“设计”的兼容版本？答案

【问题标题】：Bundler could not find compatible versions for gem "devise"?Bundler 找不到 gem“设计”的兼容版本？
【发布时间】：2015-07-17 10:58:37
【问题描述】：

我在 bundle install 上收到此错误，这没有意义，因为 devise 3.3 已经安装。

错误：

Bundler could not find compatible versions for gem "devise":
  In Gemfile:
    devise_token_auth (>= 0) ruby depends on
      devise (~> 3.2) ruby

    spree_auth_devise (>= 0) ruby depends on
      devise (~> 2.2.3) ruby

    devise (~> 3.3) ruby

【问题讨论】：

您是否要安装devise_token_auth gem？发布Gemfile.lock的相关部分
我正在尝试安装spree_auth_devise，devise_token_auth 已经安装。我已经删除了Gemfile.lock。
使用gem 'devise', '~> 3.4.1' 更新gemfile 并尝试bundle
为什么你在版本 3 中使用 spree 而在版本 1-3 中使用 spree_auth_devise ？来自：github.com/spree/spree_auth_devise#installation "请确保您使用的 spree_auth_devise 分支与您的 Spree 版本相关。"

【解决方案1】：

我有同样的问题，但版本较新，但正如输出所说，这是依赖问题

Bundler could not find compatible versions for gem "devise":
  In Gemfile:
    devise_token_auth (~> 0.1.37) ruby depends on
      devise (< 4.1, > 3.5.2) ruby

    devise (4.1.0)

我从 Gemfile 中取出 devise 的版本，以便捕获 devise_token_auth 正在使用的 devise 版本：

Using devise 4.0.2
...
Using devise_token_auth 0.1.37

所以你可以带着你获得的版本回到Gemfile：

gem 'devise', '~> 4.0.2'
...
gem 'devise_token_auth', '~> 0.1.37'
