Installing NodeJS on Ubuntu 14.04
Installing NodeJS on an installation of Ubuntu Server 14.04 is fairly straight forward but most tutorials I’ve found gloss over some details that I constantly run into any time I install it so I thought I’d clarify the procedure that I had to follow to get it installed successfully.
Run the following commands to install NodeJS and NPM
sudo apt-get install nodejs sudo apt-get install npm
After I had it installed, I tried to install the excellent project scaffolding tool Yeoman but immediately ran into permission errors as shown below.

This is a fairly well known problem and is even documented on the NodeJS website but I needed another step in between. The NodeJS directory wasn’t created so the next step failed. I had to create the directory, then change the ownership:
NOTE: Be very aware that you can properly screw up your whole OS if you do not verify that the prefix is /usr/local
and not just /usr
. You will change the permissions of everything in the /usr/bin
directory (including sudo
) and it will all break. I learnt this the hard way. Don’t do it!
chris@daenerys:/data/www$ sudo mkdir /usr/local/lib/node_modules chris@daenerys:/data/www$ sudo chown -R $(whoami) $(npm config get prefix)/{lib/node_modules,bin,share}
When I tried to install Yeoman again, I got the weird error:
npm ERR! weird error 127
This was fixed by simply running:
apt-get install nodejs-legacy
That’s it! That got NodeJS installed on my Ubuntu 14.04 Server system!

It is remarkable, rather amusing phrase
I think, that you commit an error. I can prove it.
I have read so many articles or reviews about the blogger lovers but this article is in fact a nice post, keep it up. Karna Read Lucienne
I join. So happens. We can communicate on this theme.
Very valuable idea

In my opinion you are mistaken. I can defend the position. Write to me in PM, we will discuss.
In it all charm!
