我是 RNeo4j 的新手。我正在运行以下代码。
library(RNeo4j)
graph = startGraph("http://localhost:7474/db/data", username='neo4j', password='xxxxx2')
addConstraint(graph, "Person", "name")
但是,在 addConstraint(graph, "Person", "name") 之后出现错误这是错误代码:
Error in httr::content(response)$errors :
$ operator is invalid for atomic vectors
