太阳黑子 solr rake 问题

Question

当我尝试 rake 命令时，我收到此错误。 我有一个 solr 正常运行的应用程序，现在我正在尝试使用 solr 构建一个新应用程序，但无法继续

rake sunspot:install --trace

rake aborted!

这是我的 gem 文件，

来源'https://rubygems.org'

gem 'rails', '4.2.2'

gem 'sqlite3'

gem 'sass-rails', '~> 5.0'

gem 'uglifier', '>= 1.3.0'

gem 'coffee-rails', '~> 4.1.0'

gem 'jquery-rails'

gem 'turbolinks'

gem 'jbuilder', '~> 2.0'

gem 'sdoc', '~> 0.4.0', group: :doc

gem 'sunspot_rails'


group :development, :test do
  gem 'byebug'

  gem 'web-console', '~> 2.0'

  gem 'spring'

end

有没有人能解决这个问题。

这似乎是known problem。问题是 Rails 4.1 重命名了 ActiveSupport 核心扩展中的文件，而 sunspot_rails 仍在尝试包含旧文件名。这已在this sunspot_rails commit 中解决，但它仍然was not merged 到 sunspot_rails gem 的稳定 2.0 分支。

总的来说，这个 gem 似乎已经被废弃了，所以你唯一的选择是尝试直接从 github 使用 gem 的 master 分支，而不是稳定的 2.0 分支。

您可以通过更新 Gemfile 来做到这一点，而不是：

gem 'sunspot_rails'

它会说：

gem 'sunspot_rails :github => 'sunspot/sunspot'
