无法使用h2o.init()连接到R中的h20

Question

我正在尝试使用以下命令在R Studio中第一次连接到h20：

library(h2o)
h2o.init()

R版本2.3.2和h20版本3.10.2.2。有没有办法解决这个问题，这样我就能连接上了？

H2O is not running yet, starting it now...
running command ''/usr/bin/java' -version 2>&1' had status 1
Note:  In case of errors look at the following log files:
    /var/folders/w7/vpssy9010lg4xxlwkg5f2zwm0000gn/T//RtmpZhyGXB/h2o_chrisstroud_started_from_r.out
    /var/folders/w7/vpssy9010lg4xxlwkg5f2zwm0000gn/T//RtmpZhyGXB/h2o_chrisstroud_started_from_r.err

No Java runtime present, requesting install.

如果您启用了代理，它将无法工作。

Sys.setenv(https_proxy="") 
Sys.setenv(http_proxy="") 
Sys.setenv(http_proxy_user="") 
Sys.setenv(https_proxy_user="")

帮我修好了。
