    Thank You @stro, This work great. Im rename folder MMM-MPD to mod_client and move to MagicMirror module, From MagicMirror/module/mpd_client npm install and work.

    Something like this happens to me, but my module is from user coderpussy @github , pretty new fork, maybe I got some failure from moodeaudio devs, but I dont think, so anyway here is some of my errors.

    if change folder name mmm-mpd to mpd_client errors in MM startup:
    
    alerts in MagicMirror startup:
    WARNING! Could not validate config file. Starting with default configuration. Please correct syntax errors at or above this line: ReferenceError: NodeHelper is not defined

    change folder name from mmm-mpd to mpd-client:
    Result: No errors in MM-startup but mpd-module does not start.
    
    **Looking for errors in MM-dev tools with folder named to mpd-module>**

      @dnj0104 there is probably more to the error message this also happens when there is some library required by a module not found at startup

      u can also run

      npm run config:check 
      

      to review any syntax errors in the config.js file

        in magicmirror/modules

        or in magicmirror/modules/mpd-module ?

        Thinks the whole module has to be rebuilt…

            then I got

              @dnj0104 ok, so the error that causes the default config to load is caused by some other problem.

              missing module, or some other failure

              can u show the MM startup messages (from the window where you do npm start)

              a module consists of the folder name

              MMM-MPD
              

              and its main js file

              MMM-MPD.js
              

              and inside MMM-MPD.js is the module register statement

              Module.register("MMM-MPD", {
              

              and in config.js

                {
                   module: 'MMM-MPD',
              

              this causes MM to look for the folder, filename and file contents in that order

              SO, it SOUNDS like from a prior post, that the REAL name is

              mod_client
              

              (so there must be the right folder name, file name and file contents of
              mod_client

              if so, you can rename the folder (mv is the rename command on linux)
              then in config.js you need

                module:'mod_client',
              

              see the topic ‘How to add modules’ in my signature

                  cd ~/MagicMirror
                  git checkout modules/node_modules/node_helper/index.js
