What is the fundamental difference between Bower and npm? Just want something plain and simple. I've seen some of my colleagues use Bower and npm interchangeably in their projects.

I've taken some shared code and put it in an NPM module, one I don't want to upload to the central registry. The question is, how do I install it from other projects?
The obvious way is probably to set up my own NPM registry, but according to the documentation, that involves a lot of hassle.
Can I just install an NPM module that sits on the local filesystem, or perhaps even from git?
npm install --from-git git@server:project

I am learning nodejs at the moment on Windows. Several modules are installed globally with npm.cmd, and nodejs failed to find the installed modules. Take jade for example,
npm install jade -g
Jade is installed in directory "C:\Program Files (x86)\nodejs\node_modules", but the following code will fail with a "Cannot find module 'jade'" error,
var jade = require('jade');
However, the code will run successfully when jade is locally installed (without -g option in npm). I don't want to use locally-installed modules, it's a waste of disk space for me, can someone help me to make the globally-installed modules work on Windows?

As commonly known, any npm module can be installed by running a simple command: npm install <module_name>.
I have installed a few modules that I do not use anymore and I just want to get them off. I have a few questions regarding this:
Do we have any command or process to uninstall a module from the root (something like npm uninstall <module_name>)
or will simply removing the module files do?
How does it affect us if we keep the unused modules?

This documentation answers my question very poorly. I didn't understand those explanations. Can someone say in simpler words? Maybe with examples if it's hard to choose simple words?
EDIT also added peerDependencies, which is closely related and might cause confusion.

I'm trying to install node.js via Homebrew. Unfortunately, I get this error:
➜ ~ brew install node
==> Downloading http://nodejs.org/dist/v0.8.10/node-v0.8.10.tar.gz
######################################################################## 100.0%
==> ./configure --prefix=/usr/local/Cellar/node/0.8.10
==> make install
==> Caveats
Homebrew installed npm.
We recommend prepending the following path to your PATH environment
variable to have npm-installed binaries picked up:
/usr/local/share/npm/bin
Warning: Could not link node. Unlinking...
Error: The `brew link` step did not complete successfully
The formula built, but is not symlinked into /usr/local
You can try again using `brew link node'
==> Summary
/usr/local/Cellar/node/0.8.10: 856 files, 13M, built in 103 seconds
So then I try to link node manually...
➜ ~ brew link node
Linking /usr/local/Cellar/node/0.8.10... Warning: Could not link node. Unlinking...
Error: Could not symlink file: /usr/local/Cellar/node/0.8.10/lib/node_modules/npm/scripts/relocate.sh
Target /usr/local/lib/node_modules/npm/scripts/relocate.sh already exists. You may need to delete it.
To force the link and delete this file, do:
brew link -f formula_name
To list all files that would be deleted:
brew link -n formula_name
No luck, so I try forcefully linking node...
➜ ~ brew link -f node
Linking /usr/local/Cellar/node/0.8.10... Warning: Could not link node. Unlinking...
Error: Permission denied - /usr/local/lib/dtrace/node.d
I'm not familiar with dtrace in any regard and I'm afraid to mess with permissions, so I tried to sudo..
➜ ~ git:(master) sudo brew link -f node
Password:
Error: Cowardly refusing to `sudo brew link'
You can use brew with sudo, but only if the brew executable is owned by root.
However, this is both not recommended and completely unsupported so do so at
your own risk.
I've tried uninstalling node via brew uninstall node and retrying the install with no luck.

I've just started using Grunt.js. It is pretty hard to set up and I am at the point of creating a package.json file.
Following this tutorial, it says there are 3 ways to create a package.json file.
The first is to do npm install grunt --save-dev
But what does --save-dev means? I tried looking but it ends in vain.

I have a simple package.json:
{
"name": "camapaign",
"version": "0.0.1",
"scripts": {
"start": "node app.js"
},
"engines": {
"node": "0.10.15",
"npm": "1.3.5"
},
"repository": {
"type": "svn",
"url": ""
}
}
When I execute "npm install" i get the following warning which I would like to fix:
"npm WARN package.json camapaign@0.0.1 No readme data."
I have tried adding "README.md" & "readme.txt" to the same dir as the package but with no joy. What am I missing?

I'm trying to build a github jquery-ui library using grunt, but after running npm install I still can't run the command according to the readme file. It just gives No command 'grunt' found:
james@ubuntu:~/Documents/projects/ad2/lib/jquery-ui$ grunt build
No command 'grunt' found, did you mean:
Command 'grun' from package 'grun' (universe)

Trying to install modules from github results in ENOENT error on package.json.
Easily reproduced using express
npm install https://github.com/visionmedia/express
throw error.
npm install express

Why can't I install from github?

Using npm we can install the modules globally using -g option. How can we do this in the package.json file?
Suppose, these are my dependencies in package.json file
"dependencies": {
"mongoose": "1.4.0",
"node.io" : "0.3.3",
"jquery" : "1.5.1",
"jsdom" : "0.2.0",
"cron" : "0.1.2"
}
When i run npm install, I want only node.io to be installed globally, the rest others should be installed locally. Is there an option for this?

I recently updated my node and npm installations. So maybe that has something to do with it. Also, most of my development has been at the office and today I'm working over VPN, so maybe that has something to do with it too.
Any ideas?

I am using npm v1.0.104/node 0.6.12 on ubuntu - I am receiving the error copied below while attempting to install any new modules via npm (I tested socket.io earlier using http, not https though & am wondering if that could have resulted in the issue with npm/unsigned certs). The error pops up once npm tries to resolve the 'https://registry.npmjs.org' URL. Is there anyway I can ignore the error or perhaps locate/add the cert to a trusted store in order to continue using npm.
Any insight on what needs to be done to resolve the issue will be appreciated (I would prefer to resolve the issue through configuration as opposed to re-installing if possible).
