我正在尝试安装 Graph-Aided Search 以将 Neo4j 与 ElasticSearch (2.3.1) 集成，如此处所示。但是当我尝试这个命令行时：
plugin install com.graphaware.es/graph-aided-search/2.3.2.0
我收到错误：

我在谷歌上查找了那个错误，我发现这可能是因为代理，因为我在代理后面工作，所以我尝试了一些基本上对其他人有用的东西。这是我尝试通过代理安装插件的命令行：
C:\dev\elasticsearch-2.3.1\bin> plugin -Dhttps.proxyHost=http://example.test.fr -Dhttps.proxyPort=3128 -Dhttps.proxyUser=SomeUser -Dhttps.proxyPassword=Password install com.graphaware.es/graph-aided-search/2.3.2.0
但它仍然没有用，我仍然遇到同样的错误。我强制对 Internet Explorer 上的代理进行身份验证，这在我安装带有Maven. 但是，在那种情况下它不起作用。
我正在努力将我的 Neo4j 数据库与 ElasticSearch 集成，我已经尝试了 4 天，这花费了我所有的时间，如果不成功集成就无法工作。
我非常感谢解决此错误的任何帮助或说明。谢谢你。

当我尝试替换路径时，它仍然无法正常工作。我试过这个命令行：
plugin install C:\dev\graph-aided-search-master\target\releases\graph-aided-search-2.4.1.4-SNAPSHOT.zip
我收到了这个错误信息：
-> Installing C:\dev\graph-aided-search-master\target\releases\graph-aided-search-2.4.1.4-SNAPSHOT.zip...
ERROR: Invalid prefix or suffix
我将图形辅助搜索 Zip 文件放在与插件文件相同的文件夹中，因此在C:\dev\elasticsearch-2.3.1\bin. 然后我尝试了相对路径，我收到了这条消息：
> plugin install graph-aided-search-2.4.1.4-SNAPSHOT.zip --verbose
-> Installing graph-aided-search-2.4.1.4-SNAPSHOT.zip...
