spawn node ENOENT when starting a node app

What's going wrong?

How could we reproduce this issue?

sudo /afc/bin/node /usr/local/bin/pm2 start index.js

Supporting information

I tried killing the pm2 process

Start with the reproduction command and PM2 daemon log, comparing the reported node paths and the child_process stack trace. Trace the app-start path that invokes the node executable. Done means the command starts index.js without spawn node ENOENT and PM2 reports the application online.
