Pm2: PM2 can't start app

[jhhayashi]

When I run pm2 start <app>, the process hangs after logging [PM2] Starting <app> in fork_mode (1 instance)

Running Ubuntu 14.04, Node v6.2.0, and pm2@latest

pm2.log:

Run the following commands.

sudo apt-get update # Fetches the list of available updates
sudo apt-get upgrade # Strictly upgrades the current packages
sudo apt-get dist-upgrade # Installs updates (new ones)

Then.

sudo npm install pm2@latest -g

Then

pm2 delete all
pm2 update
sudo reboot
pm2 -v

You should get

1.1.3

That will solve your issue. At least it did for me on the same OS.

Thanks for the suggestions! My problem ended up being because there were two versions installed, one in /usr/local/bin and one in /usr/bin. The older version was listed first in my $PATH variable.
