我尝试使用ArangoDB作为Tinkerpop的community supported provider，以便在Python项目中使用Gremlin，但我收到以下错误：
[ERROR] DefaultGremlinScriptEngineManager - Could not create GremlinScriptEngine for gremlin-groovy
java.lang.IllegalStateException: javax.script.ScriptException: javax.script.ScriptException: groovy.lang.MissingPropertyException: No such property: graph for class: Script1我已经按照Wiki定义了properties和yaml配置文件。
下面是我的properties配置conf/modern-arangodb.properties：
gremlin.graph = com.arangodb.tinkerpop.gremlin.structure.ArangoDBGraph
gremlin.arangodb.conf.graph.db = tinkerpop
gremlin.arangodb.conf.graph.name = modern
gremlin.arangodb.conf.graph.vertex = Place
gremlin.arangodb.conf.graph.edge = Transition
gremlin.arangodb.conf.arangodb.hosts = 127.0.0.1:8529
gremlin.arangodb.conf.arangodb.user = root
gremlin.arangodb.conf.arangodb.password = openSesame下面是我的yaml配置conf/gremlin-server-arangodb.yaml：

问题
问题与配置有关。
配置文件X1 M0 N1 X提到由属性文件定义图的键/值对列表：
然后在scriptEngines.gremlin-groovy.插件中引用：
它指定一个名为
g的图形。(In脚本文件
scripts/empty-sample.groovy）：全局
graph未定义，实际上在yaml文件中称为modern。解决方案
因此，对
gremlin-server-arangodb.yaml文件进行了微小更改。此外，更改了conf/modern-arangodb.properties图表名称以匹配。更新的
conf/modern-arangodb.properties：更新的
conf/gremlin-server-arangodb.yaml：
