openwrt系统出现/usr/lib/lua/luci/dispatcher.lua:569: bad argument #1 to ‘pairs’ (table expected, got nil)的解决办法

今天重启docke后,进路由器后台突然出现错误

如下所示:

/usr/lib/lua/luci/dispatcher.lua:569: bad argument #1 to 'pairs' (table expected, got nil)
stack traceback:
	[C]: in function 'pairs'
	/usr/lib/lua/luci/dispatcher.lua:569: in function 'createtree'
	/usr/lib/lua/luci/dispatcher.lua:238: in function 'dispatch'
	/usr/lib/lua/luci/dispatcher.lua:121: in function </usr/lib/lua/luci/dispatcher.lua:120>

解决办法如下:

用ssh连接openwrt的主机,输入rm -r /tmp/luci-indexcache即可进入后台
