盆景-elasticsearch-rails - 不能要求“elasticsearch/rails/tasks/import”

Question

当我跑步时：

$ heroku run bundle exec rake environment elasticsearch:import:model CLASS='Artist' FORCE=true

终端的响应是：

Running bundle exec rake environment elasticsearch:import:model CLASS=Artist FORCE=true on doremi... up, run.3015
Starting up a new ElasticSearch client with https://hexcode.bonsai.io
rake aborted!

(See full trace by running task with --trace)

错误似乎源自lib/tasks/elasticsearch.rake 中的这个require 语句

require 'elasticsearch/rails/tasks/import'

我检查了我所有的elastic-* gems 都是最新版本：elasticsearch-rails 和 elasticsearch-model 为 0.1.7，bonsai-elasticsearch-rails 为 0.0.4，但我确实注意到这里 @987654321 @ bonsai-elastic-search rails 依赖于 bundler 1.5 而 Heroku 使用的是 1.9.7，据我所知，这是不可能改变的。这会是问题的症结所在吗？

当我尝试部署时，我的日志中也有类似的错误

Answer 1

rails/bundler 需要 gem 按照它们在 gemfile 中声明的顺序。发生此错误是因为我在elasticsearch-rails 和elasticsearch-model 上方声明了bonsai-elasticsearch-rails。因此，通过在其他两个下方声明 bonsai-elasticsearch-rails 来解决此问题。
