node-red-contrib-zigbee2mqtt:zigbee2mqtt-server : Error: Cannot find module 'debug'

[abstract-entity]

Hello,

I got my 'node-red-contrib-zigbee2mqtt:zigbee2mqtt-server' not registering because of dependency error.

TL & NR:

cd ~/.node-red && npm install debug restart node-red

Details:

In the module 'number-allocator' used by the dependency 'mqtt' there is a call to module 'debug'. module debug was not installed from 'number-allocator' dependencies, and is not present in package.json of 'mqtt', and not in package.json of 'node-red-contrib-zigbee2mqtt'.

To fix this i've done a 'npm install debug' in my node-red node_modules directory

In node-red UI:

node-red-contrib-zigbee2mqtt
2.1.6
MODULE_NOT_FOUND

In node-red logs:

Some additionnals informations, there is different hierarchy of node_modules, maybe it's why i don't get 'number-allocator' module dependencies correctly ?

module 'node-red-contrib-zigbee2mqtt' is installed at: C:\Users\XXX\.node-red\node_modules
module 'mqtt' is installed at: C:\Users\XXX\.node-red\node_modules\node-red-contrib-zigbee2mqtt\node_modules
module 'number-allocator' is installed at: C:\Users\XXX\.node-red\node_modules
And iv'e installed module 'debug' at: C:\Users\XXX\.node-red\node_modules

I executed "npm install debug", node-red started and works fine. I don't know how I can help

Maybe in adding 'debug' in package.json, instead of running this line manually, i've made a pull request for this.
