 SELinux is preventing (pm2) from 'read, open' accesses on the file /opt/nvm/versions/node/v14.15.1/lib/node_modules/pm2/bin/pm2.

                                                             If you want to fix the label.

                                                             Then you can run restorecon. The access attempt may have been stopped due to insufficient permissions to access a parent directory in which case tr>

                                                             If you believe that (pm2) should be allowed read open access on the pm2 file by default.
                                                             Then you should report this as a bug.
                                                             You can generate a local policy module to allow this access.

                                                             allow this access for now by executing:
