我正在尝试执行此命令： aymenstien@aymenstien-VPCEH2Q1E:/usr/share/logstash$ ./bin/logstash -f /home/aymenstien/Bureau/fb.conf 以下是配置文件：

input { file { path => "/home/aymenstien/Bureau/mydoc/*" start_position => beginning codec => json sincedb_path => "/home/aymenstien/Bureau/mydoc/postj1.sincedb" } } output { stdout { codec => rubydebug } elasticsearch { hosts => "localhost:9200"; index => "fbpost" document_type => "post" timeout => 30 workers => 1 } }

我得到这个错误：
