#32177 — How to get swank-js up and running

I'm trying to install a local npm in my $HOME and then installing
swank-js. I would like to get slime/swank running with either node/npm
or js24. I'm running gentoo Linux. Here's what I did:


   curl https://www.npmjs.com/install.sh | npm_config_prefix=$HOME/javascript/npm sh
   PATH=$HOME/javascript/npm/bin/:$PATH
   type npm
   npm is hashed (/home/petter/javascript/npm/bin/npm)
   npm --version
   4.0.5
   npm install swank-js
   ...
   ...
   ...
   npm WARN enoent ENOENT: no such file or directory, open '/home/petter/package.json'
   npm WARN petter No description
   npm WARN petter No repository field.
   npm WARN petter No README data
   npm WARN petter No license field.

I would assume my problems are due to my lack of experience with JS
environments, but I'm using emacs and swank and misc inferior modes for
other development and would like to do the same for JS. Any hints or
references on how to get swank-js running?

Thanks
//Petter

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:

<https://packages.gentoo.org/packages/search?q=npm>

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.
