找不到与宝石“ spree_core”兼容的版本

Question

我刚刚浏览了Spree Commerce的“入门”指南，但在遵循该指南时遇到了错误。

我运行了以下命令：

gem install spree_cmd
bundle install

然后我在控制台中遇到以下错误

Bundler could not find compatible versions for gem "spree_core":
  In Gemfile:
    spree_auth_devise (~> 3.0.0) was resolved to 3.0.5, which depends on
      spree_core (~> 3.0.0)

    spree (~> 3.1.0) was resolved to 3.1.0, which depends on
      spree_backend (= 3.1.0) was resolved to 3.1.0, which depends on
        spree_core (= 3.1.0)

    spree (~> 3.1.0) was resolved to 3.1.0, which depends on

      spree_backend (= 3.1.0) was resolved to 3.1.0, which depends on

看起来一切都已签出-但似乎无法捆绑安装。

我的宝石文件

gem 'spree', '~> 3.1.0'
gem 'spree_gateway', '~> 3.0.0'
gem 'spree_auth_devise', '~> 3.0.0'

任何帮助都会很棒

Answer 1

您为所有3个扩展/宝石使用相同的版本。 要么（针对Spree 3.1.x）

gem 'spree', '~> 3.1.0'
gem 'spree_gateway', '~> 3.1.0'
gem 'spree_auth_devise', '~> 3.1.0'

或者，（对于Spree 3.0.x）

gem 'spree', '~> 3.0.0'
gem 'spree_gateway', '~> 3.0.0'
gem 'spree_auth_devise', '~> 3.0.0'
