電球を neo4j 2.1.5 に接続するにはどうすればよいですか。次の手順に従いましたが、役に立ちません。

  • ダウンロードして解凍したneo4j 2.1.5。

  • ダウンロードして解凍した neo4j gremlin プラグイン 2.1.5。

  • gremlin プラグインからすべての jar を $NEO4J_HOME/plugins/gremlin-plugin にコピーしました

  • これを追加するように neo4j-server.properties を変更しました。

    org.neo4j.server.thirdparty_jaxrs_classes=com.thinkaurelius.neo4j.plugins=/tp

  • neo4jを再起動しました

    bin/neo4j start

  • 拡張子が表示されない

    root@scspn0018050001:~# curl localhost:7474/db/data/ { "extensions" : { }, "node" : "http://localhost:7474/db/data/node", "node_index" : "http://localhost:7474/db/data/index/node", "relationship_index" : "http://localhost:7474/db/data/index/relationship", "extensions_info" : "http://localhost:7474/db/data/ext", "relationship_types" : "http://localhost:7474/db/data/relationship/types", "batch" : "http://localhost:7474/db/data/batch", "cypher" : "http://localhost:7474/db/data/cypher", "indexes" : "http://localhost:7474/db/data/schema/index", "constraints" : "http://localhost:7474/db/data/schema/constraint", "transaction" : "http://localhost:7474/db/data/transaction", "node_labels" : "http://localhost:7474/db/data/labels", "neo4j_version" : "2.1.5" }

  • ただし、これは正常に実行されます

    root@scspn0018050001:~# curl http://localhost:7474/tp/gremlin/execute {"success":true}

  • さて、これは私の電球スクリプトがどのように見えるかです:

    from bulbs.neo4jserver import Graph,Config, NEO4J_URI config = Config('http://localhost:7474/db/data') graph = Graph(config) james = graph.vertices.create(name="James")

  • ただし、電球スクリプトの実行時に次のエラーが発生します

root@scspn0018050001:~/neuro/src# python bulbsTest.py Traceback (most recent call last): File "bulbsTest.py", line 4, in <module> james = graph.vertices.create(name="James") File "/usr/local/lib/python2.7/dist-packages/bulbs/element.py", line 565, in create resp = self.client.create_vertex(data, keys=_keys) File "/usr/local/lib/python2.7/dist-packages/bulbs/neo4jserver/client.py", line 424, in create_vertex return self.create_indexed_vertex(data, index_name, keys=keys) File "/usr/local/lib/python2.7/dist-packages/bulbs/neo4jserver/client.py", line 1054, in create_indexed_vertex return self.gremlin(script,params) File "/usr/local/lib/python2.7/dist-packages/bulbs/neo4jserver/client.py", line 384, in gremlin return self.request.post(path, params) File "/usr/local/lib/python2.7/dist-packages/bulbs/rest.py", line 131, in post return self.request(POST, path, params) File "/usr/local/lib/python2.7/dist-packages/bulbs/rest.py", line 186, in request return self.response_class(http_resp, self.config) File "/usr/local/lib/python2.7/dist-packages/bulbs/neo4jserver/client.py", line 217, in __init__ self.handle_response(response) File "/usr/local/lib/python2.7/dist-packages/bulbs/neo4jserver/client.py", line 249, in handle_response response_handler(response) File "/usr/local/lib/python2.7/dist-packages/bulbs/rest.py", line 39, in not_found raise LookupError(http_resp) LookupError: ({'status': '404', 'access-control-allow-origin': '*', 'content-type': 'application/json; charset=UTF-8', 'content-length': '752', 'server': 'Jetty(9.0.5.v20130815)'}, '{\n "message" : "No such ServerPlugin: \\"GremlinPlugin\\"",\n "exception" : "PluginLookupException",\n "fullname" : "org.neo4j.server.plugins.PluginLookupException",\n "stacktrace" : [ "org.neo4j.server.plugins.PluginManager.extension(PluginManager.java:115)", "org.neo4j.server.plugins.PluginManager.invoke(PluginManager.java:156)", "org.neo4j.server.rest.web.ExtensionService.invokeGraphDatabaseExtension(ExtensionService.java:312)", "org.neo4j.server.rest.web.ExtensionService.invokeGraphDatabaseExtension(ExtensionService.java:134)", "java.lang.reflect.Method.invoke(Method.java:606)", "org.neo4j.server.rest.transactional.TransactionalRequestDispatcher.dispatch(TransactionalRequestDispatcher.java:139)", "java.lang.Thread.run(Thread.java:744)" ]\n}')

どんな助けでも大歓迎です。
