RACK_ENV=test be rails test test/system/service_provider_map_test.rb —seed 48088

Java HotSpot(TM) 64-Bit Server VM warning: Cannot open file logs/gc.log due to No such file or directory

测试时出现超时错误。

Java HotSpot(TM) 64-Bit Server VM warning: Cannot open file logs/gc.log due to No such file or directory

这不是错误，而是警告和误导。真正的错误信息是：

等待群集状态[绿色]和[1]个节点超时

elasticsearch-ruby库有一个测试代码，它会自己启动一个群集。它来自于此测试。https://github.com/elastic/elasticsearch-ruby/blob/6.x/elasticsearch-extensions/lib/elasticsearch/extensions/test/cluster.rb 行：579

message = "\nTimeout while waiting for cluster status [#{status}]"
message += " and [#{arguments[:number_of_nodes]}] nodes" if arguments[:number_of_nodes]
    __log message.ansi(:red, :bold)

然而，有一个错误指向了你的问题。 https://github.com/elastic/elasticsearch-ruby/issues/371 你可能需要升级你的elasticsearch-ruby版本到更新的版本。
