Install PM2 (process manager) for TX2

Hello Everyone.

I am new to TX2 development.

I want to install PM2 a process manager on TX2, since PM2 dependent on node.js, I followed steps which are detailed in https://blog.pm2.io/2018-09-19/Manage-Python-Processes/

$curl -sL https://deb.nodesource.com/setup_10.x | sudo -E bash -

this installation was not successful.

Is there any way-around to get this done.

My ultimate goal is to have a process manager which can restart a python script when it shut-down suddenly and at boot-up

I’m not sure why it would say “armh”. I am assuming this is a truncated “armhf”, which is incorrect. The TX2 is arm64/aarch64 (64-bit ARMv8-a), whereas armhf is 32-bit (32-bit ARMv7-a with hard float calling convention).

The failed fetches looking for “binary-arm64” are correct architecture, but the previous messages about “armh” are not. Either way it simply means PM2 was never released for 64-bit ARM architecture. You would have to build this yourself from source packages.

Understood.
Thank you for the reply
