问题
I'm trying to learn how to use gulp / sass / and all the other fun tools with Nodejs and I'm having an issue installing gulp-sass. The process I'm using to install everything is:
1. Start Git Bash in the project folder
2. npm init
3. npm install gulp -g
4. npm install gulp --save-dev
5. npm install gulp-sass <- this is where I get errors
Once I get to step five, I get the following error:
$ npm install gulp-sass
npm WARN package.json project@1.0.0 No repository field.
npm WARN package.json project@1.0.0 No README data
-
> node-sass@3.2.0 install \\primary\home\mendsley\profile\Desktop\project\node_modules\gulp- sass\node_modules\node-sass
> node scripts/install.js
'\\primary\home\mendsley\profile\Desktop\project\node_modules\gulp- sass\node_modules\node-sass'
CMD.EXE was started with the above path as the current directory.
UNC paths are not supported. Defaulting to Windows directory.

I'm trying this on my work computer, so I'm not sure if that matters. The system admin says there should not be any issue and other people have no issue with same package...and talking to them, they offer no help. I tried everything on my personal laptop and gulp-sass installs just fine, so it is something with my work pc.
My initial thought is it's a path issue, but then why do other packages install okay?
I did uninstall/reinstall Nodejs, but that didn't help.
Does anyone have an idea?
Thanks in advance!

Your first guess was good as it is a matter of path name. From the error message :
UNC paths are not supported. Defaulting to Windows directory.
Npm needed to access \\primary\home\mendsley\...\node_modules\node-sass so as to execute the gulp-sass installation script. But this path is a UNC path (Uniform Naming Convention) and therefore is not supported.
As a consequence, the npm command defaulted to C:/Windows instead and tries to execute the installation script of gulp-sass (install.js) but this script is, as you might guess, not present in this directory.

It could be a dependency hell problem with an older NodeJS or NPM version, too. gulp-sass depends on node-sass, which in turn depends on other packages, and they also depend on the right NodeJS and NPM version. For version 0.7.3 the full dependencies look like this:
├─┬ gulp-sass@0.7.3
│ ├── map-stream@0.1.0
│ └─┬ node-sass@0.9.6
│ ├─┬ chalk@0.5.1

I had trouble to install version 0.7.3 of gulp-sass with the latest versions of NodeJS 5.2.0 and NPM 3.5.2. This older version of gulp-sass worked only with the older version of NodeJS 0.12.9 and NPM 2.14.9, see also https://github.com/sass/node-sass/issues/1166

Look at this:
"CMD.EXE was started with the above path as the current directory. UNC paths are not supported. Defaulting to Windows directory."
You can use the pushd command. As example for --global Installation for a domain user on network share:
pushd \\server\yourpath\user\AppData\Roaming\npm
hint: you could figure out the right path for global npm installations by using %appdata%\npm in your Explorer, the cmd answers:
Z:\user\AppData\Roaming\npm>
now you can type "npm install node-sass" (or gulp-sass or whatever)
Z:\user\AppData\Roaming\npm>npm install node-sass
without --global or -g, in this path you are "global"
if finished, then popd to disconnect the Z:

I had the same issue and I fixed it with simple step.
The real problem is with autorun to set the path of your command prompt. It is related to your registry. i just deleted the autorun file in registry for command processor and it started working normally.
