我最近在R中遇到了H2o包的问题。最初作为更新开始的事情变得一团糟。
如上所述，我不得不将H2o版本从H2o版本3.16更新到最新版本（3.19）。第一个问题是让H2o与java版本1.8连接。使用来自有类似问题的用户的post，我设法修复了/~.Renviron并成功实现了Sys.getenv("JAVA_HOME")，这样就可以创建一个链接来查找java 1.8库。
现在我仍然遇到这个错误，我不知道为什么。由于某种原因，错误Network address/interface is not reachable in 150m是最重要的错误，不断重复。我不知道这是否与我在JAVA_HOME中设置/~.Renviron的方式类似。包版本也明确更新。
以下是错误的全部内容：

我不知道该怎么做，我不确定是否需要更新其他软件包，或者是否需要实施一些细微的更改才能实现。我只是想让H2o工作。
