  刚试过，它对我有用（使用Neo4j 2.0.1和2.1.0-M01）

  match (:Person)-[:ACTED_IN]->(:Movie) return count(*);
  
  -> count(*)
     172
  
  match (:Person)-[r:ACTED_IN]->(:Movie) delete r;
  
  -> Deleted 172 relationships, returned 0 rows in 172 ms
  
  match (:Person)-[:ACTED_IN]->(:Movie) return count(*);
  
  -> count(*)
     0

  删除与名为“vishal1@myemail.com”的节点关联的所有“跟随”关系：

  MATCH (n { name:'vishal1@myemail.com' })-[r:follows]->() DELETE r
  

  为我工作:)

  此外，您还可以指定标签（在我的情况下为“用户”）以区分具有相同名称的节点

  MATCH (n:User { name:'vishal1@myemail.com' })-[r:follows]->() DELETE r

  Neo4j Relationshiptypes区分大小写 . 所以 ACTED_IN 和 acted_in 将充当不同的relationshipTypes
