我从https://www.elastic.co/downloads/elasticsearch下载了elasticsearch-5.1.1.zip

然后使用以下命令通过composer下载用于Elasticsearch的Elastica A PHP客户端

composer require ruflin/elastica:dev-master

现在我要打开并进行测试.当我运行此命令

bin\elasticsearch.bat

我收到此错误：命令的语法不正确.

另一方面,如果我尝试使用Elastica A PHP客户端,则会出现如下错误：

Fatal error: Uncaught Elastica\Exception\Connection\HttpException:

我的问题是我如何使用Elasticsearch-5.1？我在哪里做错了？

问候.
