I just installed the Node Red integration in Hass.io. It seems to be working but I get the warning below in the log file. Is this a problem? How do I get the recommended LuaJIT installed?
nginx: [alert] detected a LuaJIT version which is not OpenResty’s; many optimizations will be disabled and performance will be compromised (see https://github.com/openresty/luajit2 for OpenResty’s LuaJIT or, even better, consider using the OpenResty releases from https://openresty.org/en/download.html)
