Yeoman angular app npm install error not working - angularjs

Question

I've searched far and wide for a solution to this but can't seem to find an answer. I've used Yeoman scaffolding many times before on my old Windows 8 PC but I can't get it working on my new Windows 8 PC.
I'm trying to scaffold an angular app using Yeoman. I did the following:
> npm install --global npm
> npm install --global yo bower grunt-cli
> npm install --global generator-angular
> mkdir mytodo && cd mytodo
> npm --version && yo --version && bower --version && grunt --version
2.5.1
1.4.6
1.4.1
grunt-cli v0.1.13
grunt v0.4.5
> yo angular
It runs up to the point where it runs bower install & npm install then shows a whole heap of errors. This is in the npm-debug.log file.

16 error package.json ENOENT, open 'C:\Users\melon\package.json'
16 error package.json This is most likely not a problem with npm itself.
16 error package.json npm can't find a package.json file in your current directory.
17 verbose exit [ -4058, true ]
What I find interesting in the errors is that it is referring to "C:\Users\melon\package.json". Shouldn't it be looking in the project folder for package.json (which is c:\projects\mytodo)?
Another weird thing is that it is putting a folder called node_modules inside C:\Users\melon\node_modules. This folder contains grunt, grunt-karma, jasmine-core, karma and karma-jasmine. I already have the node_modules folder in C:\Users\melon\AppData\Roaming\npm\node_modules\
If I run the following manually, it installs successfully.
> bower install
If I run the following manually, it fails.
> npm install
gifsicle#2.0.1 postinstall C:\Projects\mytodo\node_modules\grunt-contrib-imagemin\node_modules\imagemin\node_modules\imagemin-gifsicle\node_modules\gifsicle
> node lib/install.js

throw err;

Here is some relevant PATH details:
PATH=C:\Program Files\nodejs\;C:\Program Files (x86)\Git\cmd;C:\Ruby193\bin;C:\ant\bin;C:\Users\melon\AppData\Roaming\npm
I hope this is enough information for someone to show me where I have gone wrong. Thanks in advance.

Since I can not comment yet (need 50 rep.), I'm posting this as an answer.
Run Node.js as admin. This often helps a lot with those kind of errors.
Your PATH variable is correct (Ruby is there, so is Git).
I suggest you try npm install -g bower first because there seems to be something wrong with the package.
Have you already tried another generator (e.g. webapp)?
