yum install nodejs installs 200+ rpms but still won't run.

[Gary Stainburn]

I folks.

I've tried installing node.js and socket.io as I want to see if they will 
provide a solution to a problem I have.

However, the first problem I've got is that it won't run.  Below are the yum 
installs that I've tried. They look a bit iratic as I did them while trying 
things, and reading a number of web pages.  Between them they must have 
installed over 200 rpms.

The result is that when I try testing the install using 

git://github.com/learnboost/socket.io

I get the error shown below.  This seems to be a known problem on Fedora, and 
is designed to work this way.  The solution is supposed to be found at

https://npmjs.org/doc/faq.html#I-installed-something-globally-but-I-can-t...

but all I get is HTTP error 404.  Can anyone please tell me what I need to do

engine.io isn't packaged in Fedora, so it's not going to be able to find it just
from a yum install.

You need to run `npm install` in the socket.io checkout directory and it will
download all the requires modules into the node_modules folder which then can be
used. I just tested this on Fedora 24 with the tutorial socket.io from your
original message, in case you are curious.

Hi Stephen,

Thank you for replying.  I'm going to take another look at this probably over 
the weekend.

Can you please clarify your statememt.

What do you mean by "the socket.io checkout directory"
How will "npm install" know what is required?

Gary

The directory created when you ran `git clone git://github.com/learnboost/socket.io`

"Magic". (Or, more specifically, it will parse package.json and install
whatever
it needs to)
