推荐答案

我认为您可能错过了一两个步骤.请确认:

I think you probably missed a step or two. Please confirm:

1. 您是否安装了Apache ANT，然后导航到nutch文件夹并输入"ant"?
2. 您是否设置了环境变量:
   • NUTCH_JAVA_HOME:要使用的Java实现.覆盖JAVA_HOME.
   • NUTCH_HEAPSIZE:要使用的最大堆数量，以MB为单位.默认值为1000.
   • NUTCH_OPTS:额外的Java运行时选项.多个选项必须用空格分隔.
   • NUTCH_LOG_DIR:日志目录(default: $NUTCH_HOME/logs)
   • NUTCH_LOGFILE:日志文件(default: hadoop.log)
   • NUTCH_CONF_DIR:配置文件(default: $NUTCH_HOME/conf)的路径.多个路径必须用冒号':'分隔.
   • JAVA_HOME
   • NUTCH_JAVA_HOME
   • NUTCH_HOME

1. Did you install Apache ANT and then navigate to the nutch folder and type in "ant"?
2. Did you set the environment variables:
   • NUTCH_JAVA_HOME: The java implementation to use. Overrides JAVA_HOME.
   • NUTCH_HEAPSIZE: The maximum amount of heap to use, in MB. Default is 1000.
   • NUTCH_OPTS: Extra Java runtime options.Multiple options must be separated by white space.
   • NUTCH_LOG_DIR: Log directory (default: $NUTCH_HOME/logs)
   • NUTCH_LOGFILE: Log file (default: hadoop.log)
   • NUTCH_CONF_DIR: Path(s) to configuration files (default: $NUTCH_HOME/conf). Multiple paths must be separated by a colon ':'.
   • JAVA_HOME
   • NUTCH_JAVA_HOME
   • NUTCH_HOME

如果使用"ant"进行安装，则将在/nutch called /nutch/runtime/local中获得一个新文件夹，这是您必须实际运行nutct的位置.

If you install using "ant", then you will get a new folder in /nutch called /nutch/runtime/local and this is from where you must actually run nutch.
