DietPi-Software | Add Node.js version 8 as compatibility version

[MichaIng]

Status: Ready for review and testing

• VM Jessie, Koel + MineOS
  • Test Node10 installations with Node8 installed: 🈯️ netdata, 🈴 Node-red, 🈴 Blynk, 🈯️ RoonExtentionManager
  • 🈴 Blynk first (🈯️), MineOS afterwards (🈴), gyp ERR! node -v v10.6.0 v10 used, as /usr/local/bin/node (v10) is used before /usr/bin/node (v8). Messy issue with parallel node versions...
• VM Stretch, Koel + MineOS
• VM Buster, Koel + MineOS

• DietPi-Software | Add Node.js version 8 as compatibility version for software titles that do not support Node 10 yet

Okay having both installations via different install methods in parallel is really messy and leads to fails when installing Node10 dependants while Node8 is installed and the other way round.

Node n while sticking with one install method should be the better solution here. Retest same solution as we currently do with Koel...

Okay, actually it works, with npm install n -g && n 8 when used directly instead of after failure.
The broken build attempt with Node 10 seams to break further build attempts.

I will close this.
