npm install gulp-uglify --save-dev

Looks like it installs ok but it's not showing in the package.json file?

try to run the {npm init} command one more time to load the dependencies to your package.json. they will list under "dependencies" not "devDependencies". here a screenshot of my package.json http://i.imgur.com/DuYWYsW.png

you can also take a look at this link that explains the difference between the two : http://stackoverflow.com/questions/18875674/whats-the-difference-between-dependencies-devdependencies-and-peerdependencies

I ran the install 3 times and it eventually worked. I'm finding NPM is not the most reliable package manager. It's a shame there is not an alternative to install node modules.

Did you do $ npm init before this command?

Yes I used the npm init command at the beginning of the course which created the package.json file.

Yes, sometimes it works and sometimes it doesn't. Apparently I'm not the only one as many people have the same problem.

isn't that some weird permission problem? Did not you create the package.json file as a sudo or something? Just guessing. I never experienced this bug.

I may have created it using sudo? Can't remember. Enjoying learning about Gulp though, pretty cool task runner :)

Yes. I disliked Grunt in the past. i use only Gulp these days for a lot of task. I have a quite complex Angular project and i have written the build process in Gulp.

hey bro if you're on linux using sudo npm install gulp-uglify --save-dev if not you're on windows use the npm install gulp-uglify --save-dev

but if you don't create the file package.json you can't follow along , first using the npm init create the package json and after you can install all these , I hope help you with something ..
