Tinkerpop Gremlin 控制台不工作

Question

我已经安装了 Tinkerpop 3.0 M4 和 Gremlin 控制台，都是 3.0 M4。 我无法做到以下几点：

1) 加载已经存在的数据库， 2) 创建经典数据库。

通过 Tinkerpop 3，数据库在 Java 中运行良好，只是 Gremlin 控制台不行。 在打开数据库时，我在安装 OrientDB 时遇到了与 Gremlin 2.6 相同的问题，因此这不是由于 OrientDB 2.0M2 和 Grails 2.6 或 3.0M4（也不是 M5）之间的版本不兼容。 我不知道是什么问题。

1) 这是我在 Gremlin 中给出的打开数据库的命令：

g = new OrientGraph("local:/opt/orientdb/databases/dbname", "user", "password");

这是我得到的例外：

groovysh_evaluate: 3: unable to resolve class OrintGraph
@ line 3, column 5.
g = new OrintGraph("local:/opt/orientdb/databases/circletask");
   ^

2) 这是创建教程数据库的命令：

gremlin> Graph g = TinkerFactory.createClassic();

这是我得到的例外：

No such property: TinkerFactory for class: groovysh_evaluate

Answer 1

我发现该插件在默认情况下未按预期激活：

gremlin> :plugin list
         ==>tinkerpop.server
         ==>tinkerpop.gephi
         ==>tinkerpop.sugar
         ==>tinkerpop.utilities
         ==>tinkerpop.tinkergraph

解决了这个问题：

:plugin use tinkerpop.server
:plugin use tinkerpop.tinkergraph
:plugin use tinkerpop.utilities

Answer 2

错误说：

groovysh_evaluate: 3: unable to resolve class OrintGraph
 @ line 3, column 5.
   g = new OrintGraph("local:/opt/orientdb/databases/circletask");

看来您在 OrintGraph 中拼错了 OrientGraph 类？尝试使用 OrientGraph。

Answer 3

目前还没有针对 TinkerPop3 的 OrientDB 实现。
