Question

好的，所以我在构建Docker镜像时遇到了错误（想象它类似于部署步骤，或者如果你不熟悉Docker则会进行Heroku部署）。

预编译步骤发生时，:test和:development组中的宝石正在寻找，因为我已经捆绑了--without development test - 因为我不想拥有QT只是为了capybara-webkit不会在bundle上出错 - 预编译步骤会抛出错误。

错误始终是以下的变体：

Could not find <gem-name> in any of the sources (Bundler::GemNotFound)

我的Gemfile：

source 'https://rubygems.org'

  # gem 'spring'
end

发生错误的Dockerfile中的行是：

RUN /bin/bash -l -c "RAILS_ENV=production bundle exec rake assets:precompile RAILS_GROUPS=assets --trace"

所以基本上，我真正追求的是rake任务的等效--without test development。我能这样做吗？根据一些建议，我已经改变了（在application.rb中）：

Bundler.require(*Rails.groups)

到

Bundler.require(:default, :assets, Rails.env)

任何人都有Rails-fu足以解决这个问题？我查看了文档和SO，以及询问我的同事，但我仍然在撞墙挡住我的头。

Answer 1

bundle install --path vendor/cache

试试这个，让我知道它是否有效！

Rake Assets在开发或测试组中不使用Gems进行预编译
