ruby-on-rails - Rake Assets 在开发或测试组中没有 Gems 预编译

Question

好的，所以我在构建我的 Docker 镜像时遇到了一个错误(将其视为类似于部署步骤，如果您不熟悉 Docker，则可以将其视为 Heroku 部署)。

当预编译步骤发生时，正在寻找 :test 和 :development 组中的 Gem，因为我已经捆绑了 --without开发测试 - 因为我不想让 QT 只是为了 capybara-webkit 不会在 bundle 上出错 - 预编译步骤会引发错误。

错误总是以下的变体:

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

我的 gem 文件:

source 'https://rubygems.org'

  # gem 'spring'
end

发生错误的 Dockerfile 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 --without test development 的等价物。我可以这样做吗？根据一些建议，我已经更改了(在 application.rb 中):

Bundler.require(*Rails.groups)

到

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

有人有足够的 Rails-fu 来解决这个问题吗？我查看了文档和 SO，并询问了我的同事，但我仍在为此苦苦思索。

Answer 1

bundle install --path vendor/cache

试试这个，如果不起作用请告诉我!
