rails错误Bundler找不到与宝石宝石“ spree_backend”兼容的版本

Question

我想在狂欢中配置电子邮件设置，我根据本教程https://guides.spreecommerce.com/user/configuring_mail_methods.html添加了这个gem

  gem 'spree_mail_settings', github: 'spree-contrib/spree_mail_settings', branch: 'master'

但是运行捆绑安装会给我以下错误：

Bundler could not find compatible versions for gem "spree_backend":
  In snapshot (Gemfile.lock):
    spree_backend (= 3.0.7)

  In Gemfile:
    spree (~> 3.0.7) was resolved to 3.0.7, which depends on
      spree_backend (= 3.0.7)

    spree_mail_settings was resolved to 2.2.0, which depends on
      spree_backend (~> 3.1.0.beta)

Running `bundle update` will rebuild your snapshot from scratch, using only
the gems in your Gemfile, which may resolve the conflict.

运行包更新给我这个：

Bundler could not find compatible versions for gem "spree_backend":
  In Gemfile:
    spree_mail_settings was resolved to 2.2.0, which depends on
      spree_backend (~> 3.1.0.beta)

Could not find gem 'spree_backend (~> 3.1.0.beta)', which is required by gem
'spree_mail_settings', in any of the sources.

在我的gemfile中，我有：

gem 'spree', '~> 3.0.7'
gem 'spree_gateway', '~> 3.0.0'
gem 'spree_auth_devise', '~> 3.0.0'
gem 'spree_i18n', git: 'git://github.com/spree/spree_i18n.git', branch: '3-0-stable'
gem 'spree_mail_settings', github: 'spree-contrib/spree_mail_settings', branch: 'master'

我试图像这样的gem 'spree', '~> 3.1.0'写gem 'spree', '~> 3.1.0'但没有用

Answer 1

〜> 3.0.7等效于> = 3.0.7和<3.1

与其尝试弄清什么是兼容和哪些不兼容，不如将其安装为：

gem 'spree'
gem 'spree_gateway'
gem 'spree_auth_devise'
gem 'spree_i18n', git: 'git://github.com/spree/spree_i18n.git', branch: '3-    0-stable'
gem 'spree_mail_settings', github: 'spree-contrib/spree_mail_settings', branch: 'master'

然后我将捆绑安装和捆绑更新。 然后，我将检查gemfile.lock，并查看这些gem版本本身。 希望它能解决。

Answer 2

删除您的Gemfile.lock文件，然后运行bundle install和bundle update 。 我不确定此选项是否可以正常工作，请尝试一下。
