Node executables not doing anything

I have some node executables installed on an Ubuntu server but whenever I try to execute them nothing happens. I don't even get an error message. I know they're in my path because which executable_name works. When I do which -a node I get two outputs:

/usr/sbin/node  
/usr/bin/node

I feel like this has something to do with the problem but I have no idea what to do. Help.

Solution 1:

According to this answer:

sudo apt-get --purge remove node
sudo apt-get --purge remove nodejs
sudo apt-get install nodejs

# Confirm it worked
node --version       # v0.10.13
ls -la `which node`  # ... /usr/bin/node -> /etc/alternatives/node

Solved my problem.

Solution 2:

Probably sudo apt-get install nodejs-legacy would also do what you want. See http://lists.debian.org/debian-devel-announce/2012/07/msg00002.html
