我正在运行搜索踢和弹性搜索，我一直在尝试重新创建我的索引，因为我的 rails 应用程序崩溃了，但这也一直失败。我对此很陌生，所以感觉很迷茫。
我跑rake environment elasticsearch:import:all FORCE=y
但错误是
Starting up a new ElasticSearch client with

我们今天早上遇到了同样的问题。
弹性搜索模型文档告诉您像这样设置模型：
class User < ActiveRecord::Base
include Elasticsearch::Model
include Elasticsearch::Model::Callbacks
#The rest of your mode...
end
User.import
但是在导入现有数据之前，您需要删除User.import然后运行rake environment elasticsearch:import:all FORCE=y，一切都会顺利进行。
请记住在运行 rake 任务后添加User.import，以便正确导入您的新用户。
祝您编码愉快！
尝试在
Rails 控制台中YourModelName.import(force: true)。
