创建索引时出现Elasticsearch错误，可能是由于模块Kuromoji安装不正确

Question

我正在尝试为我刚刚获得访问权限的Rails应用程序设置本地环境，该应用程序使用Elasticsearch 1.3和两个模块(kuromoji和smartcn)。

我已经按照说明安装了Elasticsearch和模块，当我启动elasticsearch时，我得到了以下输出：(注意插件行，它让我相信它们已经加载了)

$ elasticsearch

但是，当我尝试运行rake任务来索引和导入数据时，我得到了以下错误，这让我相信Kuromoji没有加载，或者可能发生了其他事情。

[!!!] Error when creating the index: Elasticsearch::Transport::Transport::Errors::BadRequest
[400] {"error":"IndexCreationException[[development-activities] failed to create index]; nested: ElasticsearchIllegalArgumentException[failed to find token filter type [kuromoji_readingform] for [katakana_readingform]]; nested: NoClassSettingsException[Failed to load class setting [type] with value [kuromoji_readingform]]; nested: ClassNotFoundException[org.elasticsearch.index.analysis.kuromojireadingform.KuromojiReadingformTokenFilterFactory]; ","status":400}

我很感谢在这里解决这个问题的任何帮助。

这条消息似乎是关于kuromoji插件的。尝试安装插件。

cd path/to/yourelasticsearch
bin/plugin install elasticsearch/elasticsearch-analysis-kuromoji/2.7.0

请注意，您需要安装正确版本的kuromoji插件，这取决于您安装的elasticsearch版本。参见here。
