Problems to start the new Node-Red Version

Hello, can anybody help me? .. i have start with pm2 the node-red via boot .. but they start the version 3.0.2

when i stop the node-red from pm2 than i can start manual the node-red 3.1.8
can anybody help me what i can do to start the new version of node-red with pm2?

You must have installed two versions of node red in different places somehow. Look at your settings for pm2 and work out why it is picking up the wrong one.
