使用PyOrient创建数据库时“超时：超时”

Question

我有一个OrientDB的本地实例（版本：2.2.20），我将它用作图形数据库。当我尝试从DB Client实例创建新数据库时，它会给出超时错误。代码如下所示，

Error in route(from = startingpoint, to = stoppoint, mode = "bicycling",  : 
  (list) object cannot be coerced to type 'double'
Called from: route(from = startingpoint, to = stoppoint, mode = "bicycling", 
    structure = "route")

do.call(rbind.data.frame, lapply(names(calculatedroutes), function(x) {
+   cbind.data.frame(route=x, calculatedroutes[[x]], stringsAsFactors=FALSE)
+ })) -> long_routes

客户端对象为我提供了其他现有数据库，并且连接没有任何问题。请建议我处理它
