In general you should look for a Gentoo package to install, but in this case 
it appears that there is none, at least no official one:

It is hard to tell apart what is your input and what is a program’s output.  
When you post logs of shell sessions, always include the minimum prompt (you 
can mask non-essential confidential information, we will understand it 
anyway).

IIUC, you are attempting to install the npm package “swank-js”, but you are 
doing that in your home directory (/home/petter) where there is no 
package.json.  In order to install a package by name only, the package needs 
to be registered in a configured npm registry or there needs to be a 
package.json in the current directory specifying the URI for the name.  
Otherwise you have to use the package URI.

swank-js is in the global npm registry –

<https://www.npmjs.com/package/swank-js>

–, and I have no problems installing it from there with just “npm install 
swank-js”, so ISTM that you have not set up npm properly (yet).

However, I think that npm 101 is beyond the scope of this newsgroup.

[After you fixed the problem, you might want to install “swank-js” globally 
(for all users) instead of only for your user:

  npm install -g swank-js

This will probably require “root” permission which you could get with 
sudo(8) if it is installed:

  sudo npm install -g swank-js

Again you should look for a distribution package before you use “npm 
install” directly, but again there does not appear to be one in this case.]

FYI, Gentoo really is not a Linux distribution suited for (GNU/Linux) 
beginners.

HTH.  For further information, RTFM, and please do that first the next time 
you have a problem.
