我已经在 linux 机器上成功地从 R 运行了 h2o，并且也想在 Windows 中安装它。h2o 不会为我初始化。完整的输出粘贴在下面，但关键似乎是行
[1] "Failed to connect to 127.0.0.1 port 54321: Connection refused"
curl: (1) Protocol "'http" not supported or disabled in libcurl
从这个和这个经验来看，它可能与某处的单引号和双引号有关；但这似乎不太可能，因为没有人能够让 h2o / R / Windows 组合工作，我猜有些人是。另一方面，这个问题似乎表明问题在于我的 curl 安装可能没有启用 ssl。因此，我按照 h2o 页面上的建议从该向导中从头开始下载 curl ，选择 64 位版本，通用，并选择启用 SSL 和 SSH 的版本；下载它并将它最终进入的文件夹添加到我的 Windows PATH 中。但没有区别。
我刚刚注意到我的 Java 运行时环境很旧，并且也会对其进行更新。但从表面上看，这并不是问题所在。
欢迎任何建议。

H2O is not running yet, starting it now...

-h | -help
Print this help.
-version
Print version info and exit.
-name <h2oCloudName>
Cloud name used for discovery of other nodes.
Nodes with the same cloud name will form an H2O cloud
(also known as an H2O cluster).
-flatfile <flatFileName>
Configuration file explicitly listing H2O cloud node members.
-ip <ipAddressOfNode>
IP address of this node.
-port <port>
Port number for this node (note: port+1 is also used).
(The default port is 0.)
-network <IPv4network1Specification>[,<IPv4network2Specification> ...]
The IP address discovery code will bind to the first interface
that matches one of the networks in the comma-separated list.
Use instead of -ip when a broad range of addresses is legal.
(Example network specification: '10.1.2.0/24' allows 256 legal
possibilities.)
-ice_root <fileSystemPath>
The directory where H2O spills temporary data to disk.
-log_dir <fileSystemPath>
The directory where H2O writes logs to disk.
(This usually has a good default that you need not change.)
-log_level <TRACE,DEBUG,INFO,WARN,ERRR,FATAL>
Write messages at this logging level, or above. Default is INFO.
-flow_dir <server side directory or HDFS directory>
The directory where H2O stores saved flows.
(The default is 'C:\Users\Peter Ellis\h2oflows'.)
-nthreads <#threads>
Maximum number of threads in the low priority batch-work queue.
(The default is 99.)
-client
Launch H2O node in client mode.
Cloud formation behavior:
New H2O nodes join together to form a cloud at startup time.
Once a cloud is given work to perform, it locks out new members
from joining.
Examples:
Start an H2O node with 4GB of memory and a default cloud name:
$ java -Xmx4g -jar h2o.jar
Start an H2O node with 6GB of memory and a specify the cloud name:
$ java -Xmx6g -jar h2o.jar -name MyCloud
Start an H2O cloud with three 2GB nodes and a default cloud name:
$ java -Xmx2g -jar h2o.jar &
$ java -Xmx2g -jar h2o.jar &
$ java -Xmx2g -jar h2o.jar &
