luci on lighttpd- 500 内部服务器错误

我在ubuntu 16.04上使用 lighttpd 运行 LUCI。 我使用lua5.1和luci-0.9

在 www/html/ 中的目录结构如下所示：

root@toor-VirtualBox:/var/www/html# ls
cgi-bin  cgi-bin-nodes.html  cgi-bin-status.html  index.html  index.lighttpd.html  luci  luci-static

当我运行

Lua 5.1.5  Copyright (C) 1994-2012 Lua.org, PUC-Rio
> require "luci.cacheloader"
> require "luci.sgi.cgi"
>
> luci.dispatcher.indexcache = "/tmp/luci-indexcache"
>
> luci.sgi.cgi.run()

我得到了500个内部服务器错误：

.../luci/host//usr/lib/lua/luci/statistics/datatree.lua:28: attempt to index upvalue 'sections' (a nil value)
