Openwrt出现/usr/lib/lua/luci/dispatcher.lua:569解决办法
用了很久的路由进入系统，莫名其妙出现如下错误：
/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
