Safe to remove /usr/local/bin/node?

In the past I installed Node.js. Now I tried updating it following this guide and ended up having two versions of it, node on version 0.10.7 and nodejs on version 0.12.7. To clear this up I wanted to remove it completely and reinstall it. apt-get remove nodejs worked fine, but not apt-get remove node:

Reading package lists... Done
Building dependency tree       
Reading state information... Done
Package 'node' is not installed, so not removed
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

But:

$ which node
/usr/local/bin/node

Is it safe to remove this file or will I have leftovers lurking around somewhere else?

you are installing node from binaries which is self installation (not using ubuntu software center).

When you do self installation of node usually you create a symbolic link to /usr/bin or /usr/local/bin to put in the path for everyone system-wide.

If you installed new version of node all you have to do is to remove the symlink of the old one and place the new one instead.

 ln -s /path/where/node/installed/bin/node /usr/bin/node 

Remove of course the one in /usr/local/bin or /usr/bin before.

Yes. It is safe to remove /usr/local/bin/node folder but you have to remove or edit Nodejs from the PATH in ~/.bashrc.
