Node forever doesn't work on Ubuntu 12.04.1

Question

When I fun forever on Ubuntu 12.04.1, I got the error below after upgrading node.js from v0.6.12 to v0.8.15. Before upgrading it works well. Does anyone encounter this kind of issue before?

$ forever

module.js:340
    throw err;
          ^
Error: Cannot find module './daemon.v0.8.15'

My environment is

node v0.8.15
npm 1.1.66

I installed node and npm with the command line blow

$ sudo apt-get install python-software-properties -y
$ sudo add-apt-repository ppa:chris-lea/node.js
$ sudo apt-get update
$ sudo apt-get install nodejs npm -y

I installed forever with the command line

$ sudo npm install forever -g

Answer 1

'sudo npm update -g forever' doesn't work for me. I deleted all the installed modules and install it again. The forever works. The steps are as below.

Delete the all the existing forever modules.

$ sudo rm -R /usr/lib/node_modules/forever
$ sudo rm -R /usr/local/lib/node_modules/forever

Install the forever again.

$ sudo npm install forever -g
