空指针应该是最常见也是最容易修复的错误
话说截图不带行号什么意思...

其指出错误由 NullPointerException 引起
发生于 KCommandAdminRpForPlayer.java 的第 49 行
错误报告是可以从下往上看 指出：


在调用CommandExecutor.java 中onCommand方法的第262行
KCommandBase.java 中execute方法的第15行
KCommandAdminRpForPlayer.java 中executeCommandConsole的第49行

请提供一下 KCommandAdminRpForPlayer.java 第49行附近的截图

你是不是已经修改过了 try语句怎么会出现空指针错误
