Bundler找不到与宝石spree_core兼容的版本（Spree Ruby on Rails）

Question

我刚刚在Rails上成功配置了Spree（在Rails 4.0.2 + Ruby 2.0.0以及Rails 3.2.4 + Ruby 1.9.3上），但是现在我试图在spree中添加“ spree_marketplace”和“ spree_drop_ship”，但得到这个错误

Bundler could not find compatible versions for gem "spree_core":
  In Gemfile:
    spree_marketplace (>= 0) ruby depends on
      spree_core (~> 2.0.3) ruby

    spree (>= 0) ruby depends on
      spree_core (2.2.0.beta)

目前我的Ruby和Rails版本是

$ ruby -v
ruby 2.0.0p353

$ rails -v
Rails 4.0.2

我的宝石文件

Answer 1

正如@AlexD所写，您受到spree_marketplace gemspec的限制。 您可以做两件事，要么用某人的叉子（或创建自己的）碰碰到gemspec（尽管这种碰碰会破坏某些东西，但您必须自己检查一下并运行是否已写好规范）：

gem 'spree', :github => "spree/spree", branch: '2-1-stable'
gem 'spree_auth_devise', :github => "spree/spree_auth_devise", branch: '2-1-stable'
gem 'spree_marketplace', github: 'emcgee/spree_marketplace'
gem 'spree_drop_ship', github: 'jdutil/spree_drop_ship'

或降级到spree_marketplace允许的最高版本：

gem 'spree', :github => "spree/spree", branch: '2-0-stable'
gem 'spree_auth_devise', :github => "spree/spree_auth_devise", branch: '2-0-stable'
gem 'spree_marketplace', github: 'jdutil/spree_marketplace'
gem 'spree_drop_ship', github: 'jdutil/spree_drop_ship', branch: '2-0-stable'

如果要使用Rails 4，则应使用Spree 2.1 AFAIK。

Answer 2

您需要在Gemfile中指定要使用的Spree版本。 想要使用的spree_marketplace gem适用于2.0系列的Spree版本，从2.0.3到2.0.7（最新版本低于2.1.0）。 选择该范围内的版本，并为spree宝石指定该版本。 否则，Bundler会认为您要使用spree版宝石的最新版本。

像这样：

gem 'spree', '2.0.7', :github => "spree/spree"

如果要使用新的2.2.0版本的Spree，则必须自己创建spree_marketplace的更新版本，或者让其他人来做！
