Question

我正在尝试将rails_admin与rails5应用程序一起使用。 rails_admin 0.8.1没有用，因为

Bundler找不到gem＆＃34; rails＆＃34;的兼容版本：In   快照（Gemfile.lock）：       rails（= 5.0.0.beta1）

在Gemfile中：       rails（＆lt; 5.1，＆gt; = 5.0.0.beta1）
rails_admin was resolved to 0.8.1, which depends on
  rails (~> 4.0)

然后我尝试使用

从github使用最新的代码

gem＆＃39; rails_admin＆＃39;，git：＆＃39; https://github.com/sferik/rails_admin.git＆＃39;

现在我的机架依赖性相互冲突。

在快照（Gemfile.lock）中：       rack（= 2.0.0.alpha）

在Gemfile中：       rails（＆lt; 5.1，＆gt; = 5.0.0.beta1）被解析为5.0.0.beta1，这取决于         actionmailer（= 5.0.0.beta1）被解析为5.0.0.beta1，这取决于           actionpack（= 5.0.0.beta1）被解析为5.0.0.beta1，这取决于             机架（〜> 2.x）
rails_admin was resolved to 0.8.1, which depends on
  rack-pjax (~> 0.7) was resolved to 0.7.0, which depends on
    rack (~> 1.3)

rails (< 5.1, >= 5.0.0.beta1) was resolved to 5.0.0.beta1, which depends on
  sprockets-rails (>= 2.0.0) was resolved to 3.0.0, which depends on
    sprockets (>= 3.0.0) was resolved to 3.5.2, which depends on
      rack (< 3, > 1)

devise was resolved to 4.0.0.pre.dev, which depends on
  warden (~> 1.2.3) was resolved to 1.2.4, which depends on
    rack (>= 1.0)

devise was resolved to 4.0.0.pre.dev, which depends on
  warden (~> 1.2.3) was resolved to 1.2.4, which depends on
    rack (>= 1.0)

开始使用rails5还为时过早吗？我应该回到rails4.2吗？

Answer 1

我看到RA有Rails5 gemfile https://github.com/sferik/rails_admin/blob/master/gemfiles/rails_5.0.gemfile。我会尝试升级到该文件中提到的所有宝石。

Answer 2

我通过这样做来解决：

gem 'rails_admin', github: 'sferik/rails_admin'
gem 'rack-pjax', github: 'afcapel/rack-pjax'
gem 'remotipart', github: 'mshibuya/remotipart', ref: '3a6acb3'
