grunt sass task producing errors due to bourbon package

I am writing a grunt task file for my project. I have defined the sass task in that and installed all the required dependencies. I am able to run the same gruntfile on my friends computer, but on my computer the sass task produces this error.
Running "sass:dist" (sass) task
Syntax error: Invalid CSS after " webkit-image": expected ")", was ": -webkit- + $p..."
on line 21 of /home/chitrank/Documents/shaastr/frontend/frontend/frontend/app/minovate/bower_components/bourbon/dist/helpers/_linear-angle-parser.scss
from line 10 of /home/chitrank/Documents/shaastr/frontend/frontend/frontend/app/minovate/bower_components/bourbon/dist/_bourbon.scss
from line 6 of app/sass/main.scss
Use --trace for backtrace.
Warning: Exited with error code 1 Use --force to continue.
Aborted due to warnings.
Due to this error I am not able to perform sass task and need to do it on my friend's computer. I am also adding my Gruntfile.js for better overview of what my grunt tasks are and how it is working, please have a look.

If anyone has resolved this problem before please let me know.

This discussion says that this issue is caused by incompatibility between the versions of Sass and Bourbon.
Bourbon 4 require at least Sass 3.3 so if you are running a lower version you need to either downgrade Bourbon to 3.x or upgrade Sass

Grunt file not doing a proper build

So I started my project using Yeoman with 'yo angular'. Since, I have added additional file structure (i.e. broke views and scripts into folders based on project area), added additional packages to use in my project, etc.... Running 'grunt serve' and it loads and works great locally as it should. Prior to this I hadn't done anything with grunt so just went with the default provided with the build from yo angular. Hadn't modified it yet. So when time to port this to a server and going to run just 'grunt' so that I get what I need to deploy, this is where I am having issues.
Here is my gruntfile.js:
// Generated on 2015-04-02 using generator-angular 0.11.1
'use strict';
// # Globbing
// for performance reasons we're only matching one level down:

So when I do this, the first thing that fails is the test with this:
PhantomJS 1.9.8 (Windows 8): Executed 2 of 2 (2 FAILED) ERROR (0.04
secs / 0.016 secs) Warning: Task "karma:unit" failed. Use --force to
continue.
So then I simple run 'grunt --force'. Then, it seems to run fine, but has many warnings and in the "dist" folder, I only get root level html files (the index.html and 404.html) and just the fonts folder. None of the other views and none of the scripts or anything are shown or taken care of. My project folder structure is as shown in the attached 2 images:
and
Again, I simple want to build it all to one folder as I thought it did. Not worried yet of test and all.
Can anyone here assist please?
Thanks much.

Your copy task is only copying the root level html files and html files under the directory views which you don't have on your project.
Assuming that brok, emp, ppt, shared has html files in it; I suggest you try to modify your copy task to be:
copy: {
dist: {
files: [{
expand: true,
dot: true,
cwd: '<%= yeoman.app %>',
dest: '<%= yeoman.dist %>',
src: [
'*.{ico,png,txt}',
'.htaccess',
'*.html',
'brok/{,*/}*.html',
'emp/{,*/}*.html',
'ppt/{,*/}*.html',
'shared/{,*/}*.html',
'images/{,*/}*.{webp}',
'styles/fonts/{,*/}*.*'
]
}, ....
},
Also htmlmin to be modified like this
htmlmin: {
dist: {
options: {
collapseWhitespace: true,
conservativeCollapse: true,
collapseBooleanAttributes: true,
removeCommentsFromCDATA: true,
removeOptionalTags: true
},
files: [{
expand: true,
cwd: '<%= yeoman.dist %>',
src: ['*.html', 'brok/{,*/}*.html', 'emp/{,*/}*.html', 'ppt/{,*/}*.html', 'shared/{,*/}*.html'],
dest: '<%= yeoman.dist %>'
}]
}
},

Grunt -- Running a Connect and Express server on the same port

I'm newb-ish when it comes to Grunt, and am curious if it's possible to run both servers on the same port together. I'm having some trouble with it already... the problem is probably in the Grunt file.
I'm using grunt-contrib-connect and grunt-express-server for the respective functions. Ideally, what happens is grunt server will spin up the connect server, livereload, and the express server.
My Grunt file is below. Thanks!!

You may want to check out https://github.com/blai/grunt-express which has all this built in

If you want to use the same port:
Use a different protocol for both Connect and Express
Use a subdomain for either Connect or Express
Use a virtual host

gruntfile.js adding video files to distribution and updating html

I have updated my gruntfile.js to add video files to the distribution. I can see the video files prepended like this 949494.movie.mp4 but the html in index.html isn't updating with this new file name. What am I missing?

I realize this was asked a long time ago, but since it hasn't been answered and I ran into this recently... why not?
Apparently, video files are not covered by usemin by default. In this case, you need to explicitly specify which file formats usemin needs to look for by using Patterns.
enter link description here
So for example:
usemin: {
html: ['<%= yeoman.dist %>/*.html'],
options: {
assetsDirs: ['<%= yeoman.dist %>', '<%= yeoman.dist %>/images', '<%= yeoman.dist %>/videos'],
patterns: {
html: [
[/(videos\/.*?\.(?:mp4|ogg|webm))/gm, 'Update HTML to reference revved videos'],
[/(images\/.*?\.(?:gif|jpeg|jpg|png|webp|svg))/gm, 'Update HTML to reference revved images'],
[/(styles\/.*?\.(?:css))/gm, 'Update HTML to reference revved css'],
[/(scripts\/.*?\.(?:js))/gm, 'Update HTML to reference revved js']
]
}
}
},
Hope this helps!

yeoman / grunt and requirejs - dont concatenate (optimize) output

I'm using the basic yeoman webapp template with requirejs and now I want to build it. However, I don't want grunt to concatenate every module into one file (the optimized way).
How do I stop it from doing that and copying over all the modules by itself?

You can see more here, explains how to use yeoman with requirejs in 2014: http://www.webdesignporto.com/3-steps-to-fully-automatized-javascript-environment-with-yeoman-and-require-js-for-lazy-people/

The useminPrepare and usemin tasks are responsible for concatenating scripts (and styles). They use HTML comments to determine what to concat/minify.
Here's a bit of HTML in my index.html from a run of generator-angular yesterday:
<!-- build:js({.tmp,app}) scripts/scripts.js -->
<script src="scripts/app.js"></script>
<script src="scripts/controllers/main.js"></script>
<!-- endbuild -->
Notice how the <!-- build --> comments wrap the scripts? These comments instruct usemin to concatenate and minify the scripts between build and endbuild.
You can simply remove the <!-- build --> and <!-- endbuild --> comments from around the <script> tags, and usemin will not concat and minify them.
(You may need to adjust the Gruntfile.js task build if you get errors from uglify when running grunt. Try removing uglify from the list.)

You can edit your Gruntfile's task definition for 'build' to remove concat/usemin/useminprepare sub-tasks. Or like #jevets says, remove the <!-- build -->...<!-- endbuild -->comments from your HTML.
