I'm trying to install uglifyjs on my computer from local folders.
I downloaded all dependencies of uglifyjs, including dependencies of dependencies, and they are all available in my folder C:\npm\node_modules
I'm working on Windows XP, and when I'm trying to install uglify-js from \node_modules\uglify-js using the command npm install -g node_modules\uglify-js (global because I'm on a Windows machine, to be able then to execute uglifyjs using the command: uglifyjs -o output.js input.js) it's trying to download dependencies from Internet (I can't because I'm under a security proxy, that's why I downloaded all dependencies manually)

I tried to install all dependencies manually, it seems to work fine though
npm list:

This is all folders on my node_modules folder

I installed uglify-js without global command -g, it worked fine

But when I execute the uglifyjs command node C:\npm\node_modules\.bin\uglifyjs output.js input.js, I have this error:

Do you have any suggestion?
Thanks.
npm installfrom the local directory? Are you using a package.json file? If so, you should be able to specify the repo where it lives.
