If additional nodes does not work….

• This function uses Node-RED Destktop builtin npm.
  Some npm modules need to be compiled from node binary or C/C++ when installing.
  In such cases, you need to install node.js before.
  If so, please install node v12.x.x from Node.js official site and retry to install them.

  You can test to use node command with this flow.

How to use excluded standard nodes

• You can activate them at [Nodes exclude] form in [File]-[Settings…].
  When you activate the MQTT node, Delete 10-mqtt.js from [Node exclude].

• Default [Nodes exclude] is below

  10-mqtt.js
  16-range.js
  31-tcpin.js
  32-udp.js
  89-trigger.js
  

• I have selected default [Nodes exclude] to simple the first look for beginners.
  There is not technical reason.
