redisgraph - (错误)RedisGraph 中的 ERR 未知命令 'GRAPH.QUERY'

Question

我不明白为什么 RedisGraph 命令“GRAPH.QUERY”不起作用，我已经使用此 tutorial 下载并安装了 Redis 。当我通过插入此命令来测试 RedisGraph 时:

GRAPH.QUERY MotoGP "CREATE (:Rider {name:'Valentino Rossi'})-[:rides]->(:Team 
{name:'Yamaha'}), (:Rider {name:'Dani Pedrosa'})-[:rides]->(:Team {name:'Honda'}), (:Rider 
{name:'Andrea Dovizioso'})-[:rides]->(:Team {name:'Ducati'})"

它抛出错误:

(error) ERR unknown command 'GRAPH.QUERY'

以下是有关 RedisGraph 版本的信息:

Answer 1

原因是: 您只安装了Redis。您还需要安装 Redis Graph，它是 Redis 的一个单独模块。

建议: 我建议您安装 Docker，然后运行以下命令:

docker run -p 6379:6379 -it --rm redislabs/redisgraph
