所需端口 54321、54322 在 h2o 中的 R 上不可用错误

Question

我无法在 MRO3.3 中启动 H2o h2o.init() 给出了以下输出

输出：

即使我更改了端口，我也无法访问 h2o 我尝试重新安装 java 和 h2o，但到目前为止运气不佳

日志的最后一行解释了这个问题：

08-02 00:40:36.613 127.0.0.1:54321       19672  main      FATAL: On /127.0.0.1 some of the required ports 54321, 54322 are not available, change -port PORT and try again.

它说，"some of the required ports 54321, 54322 are not available"。确保这些端口可用，或者如果它们不可用，则只需使用 h2o.init().

中的 port 参数在不同的端口上启动 H2O

所需端口 54321、54322 在 h2o 中的 R 上不可用错误

Required ports 54321, 54322 are not available error on R in h2o
