Elasticsearch MAC 10.14.6 与 Java jdk-12.0.2.jdk

Question

我在 Mac OS 14.0.6 Elasticsearch 上安装了 brew。它必须是 ES V 6 - 而不是 7。但我也安装了 7 - 同样的错误。那么jdk一定有问题吗？一切运行良好后，我从命令开始elasticsearch，并在控制台中收到以下错误：

删除v7并安装v6后出现同样的问题。通过手动删除 ES 配置并重新安装 ES 来解决此问题brew remove elasticsearch rm -fR `brew --prefix`/etc/elasticsearch brew install elasticsearch
