Observe NVM_INC, NVM_BIN and PATH, which node and node -v (v20.13.1)
pm2 -v reports lots of warnings and version 2.6.1

All warnings disapear if I use node v12.14.0 so it seams as a pm2 problem related to node v20.13.1 or may be a node v20.13.1 problem

Start by reproducing pm2 -v with Node v20.13.1 on Ubuntu 22.04.4 and compare its output with Node v12.14.0, using the reported environment and PATH details. Trace the source of the circular-dependency warnings and establish a supported resolution; done means the warnings no longer appear with the affected Node version.
