For security reasons and to have the latest features available, Node.js (and with it NPM) are updated fast and often. The current long-term release is v12.
App Dev Pack in version 1.0.2 only supports v8 and v10 of Node.js.
I tried it with v12, but even the "build from source" doesn't work for me.
IMHO, App Dev Pack should always support the current Node.js version.
