What is the best way to install the latest node-red (1.0.3) on a Pi zero (ARMv6) given that nodejs no longer supports ARMv6?
If you install Node v10 before running the Pi install script it will work just fine. I have several on v1.0.3
The recommended pi install script should still work fine and install v10.19. The problem arises if you need v12, but that should not be for a while yet, node-red still works with nodejs v8.
