我最近更新到High Seirra，不确定这是否意味着什么，我现在在尝试重新索引Active Record Model时遇到此错误。
我尝试过的事情。我重新安装了RVM，Ruby，Elasticsearch。仍然得到相同的错误。
我团队中的其他人做了同样的升级，他们运行得很好。 以下是我得到的错误。
Elasticsearch::Transport::Transport::Errors::BadRequest: [400] {"error":{"root_cause":[{"type":"mapper_parsing_exception","reason":"Failed to parse mapping [_default_]: Could not convert [word_start.index] to boolean"}],"type":"mapper_parsing_exception","reason":"Failed to parse mapping [_default_]: Could not convert [word_start.index] to boolean","caused_by":{"type":"illegal_argument_exception","reason":"Could not convert [word_start.index] to boolean","caused_by":{"type":"illegal_argument_exception","reason":"Failed to parse value [analyzed] as only [true] or [false] are allowed."}}},"status":400}

检查您的Gemfile.lock并在此处检查elasticsearch的版本。如果它与本地系统中的elasticsearch版本不匹配，请删除gemfile.lock文件并运行捆绑软件。这为我解决了这个问题。

我有同样的问题，我不得不升级我的Mac上的elasticsearch
brew upgrade elasticsearch
