如何用H2O更新R上的H2O集群版本？

Question

每当我在Mac上从R导入h2o时，我都会看到一条警告消息

Your H2O cluster version is too old (8 months and 2 days)!
Please download and install the latest version from http://h2o.ai/download/

因此，我按照h2o主页(http://h2o-release.s3.amazonaws.com/h2o/rel-zipf/3/index.html)的安装指南运行

# The following two commands remove any previously installed H2O packages for R.
if ("package:h2o" %in% search()) { detach("package:h2o", unload=TRUE) }
if ("h2o" %in% rownames(installed.packages())) { remove.packages("h2o") }

# Next, we download packages that H2O depends on.
pkgs <- c("RCurl","jsonlite")
for (pkg in pkgs) {
if (! (pkg %in% rownames(installed.packages()))) { install.packages(pkg) }
}

# Now we download, install and initialize the H2O package for R.
install.packages("h2o", type="source", repos="http://h2o-release.s3.amazonaws.com/h2o/rel-zipf/3/R")

但是这种方法不能解决问题，而是会产生错误。

R is connected to the H2O cluster: 
    H2O cluster uptime:         10 days 3 hours 
    H2O cluster timezone:       America/New_York

    H2O cluster version:        3.32.0.1

Error in h2o.init() : 
  Version mismatch! H2O is running version 3.32.0.1 but h2o-R package is version 3.32.1.3.
         Install the matching h2o-R version from - https://h2o-release.s3.amazonaws.com/h2o/rel-zermelo/1/index.html
In addition: Warning message:
In h2o.clusterInfo() : 
Your H2O cluster version is too old (8 months and 2 days)!
Please download and install the latest version from http://h2o.ai/download/

有办法更新集群的h2o版本吗？不过，我并没有在windows机器上经历过这个问题。

现在看来，h2o集群版本已经更新到CRAN版本了。简单地从CRAN重新安装解决了这个问题。
