问题
So I am using Gulp Sass with gulp-changed (i've also tried gulp-newer with the updated syntax changes) and watching all the scss files in my folders.
When I change a base scss file it will compile without any problems.
However if I change a partial it won't compile the sass file that has a dependency on that partial.
Gulp
var SRC = './stylesheets/**/*.scss';
var DEST = './stylesheets';
gulp.task('sass', function() {
return gulp.src(SRC)
.pipe(changed(DEST, { extension: '.css' }))
.pipe(plumber({
errorHandler: handleErrors
}))
.pipe(sourcemaps.init())
.pipe(sass({
includePaths: [
'C:/var/www/mobile 2/stylesheets'
]}))
.pipe(sourcemaps.write('./'))
.on('error', handleErrors)
.pipe(gulp.dest(DEST))
});
Folders
├── scss
│ └── base.scss
│ ├── _partial1.scss
│ └── _partial2.scss
│ └── anotherBase.scss
│ ├── _anotherBasePartial1.scss
│ └── _anotherBasePartial2.scss
Making changes to base.scss || anotherBase.scss changes made, making changes to partial1.scss nothing.
As you can see in the log:
[15:14:02] Starting 'sass'... //here i changed _partial1.scss
[15:14:03] Finished 'sass' after 248 ms
[15:18:20] Starting 'sass'...
[15:18:20] Finished 'sass' after 289 ms
[BS] File changed: c:\var\www\mobile 2\stylesheets\sitescss\responsive\tools\base.css
[15:18:24] Starting 'sass'...
[15:18:24] Finished 'sass' after 289 ms
[BS] File changed: c:\var\www\mobile 2\stylesheets\sitescss\responsive\tools\anotherBase.css
I would like it to compile the scss whenever a partial is changed.
回答1:
A bit late for the show, but if I understand you right; you want to run your build when you change ANY scss file, whether that being a partial or not, right? (but not including the partials in the build itself – as that is handled by sass @import).
I normally use this approach:
var scss_source = [ 'path/to/scss' ],
partials_source = [ 'path/to/partials' ];
gulp.task('scss', function () {
gulp.src( scss_source )
...
});
var scss_watcher = gulp.watch([ scss_source, partials_source ], [ 'scss' ]);
I pass only the scss_source to the build, but BOTH sources to the watcher. That way I can seperate all partials from the rest of the scss sources, but have changes to any of the files trigger a build. And I don't have to include yet another module for handling this.
I usually keep my partials in separate directories (think shared, and not mixed with other scss files).
Hope this makes sense in your case – otherwise I do apologize.
回答2:
try
var SRC = './stylesheets/**/{*.scss,_*.scss}';
if partials lay in the same folder or a subfolder.
回答3:
https://www.npmjs.com/package/gulp-changed
By default it's only able to detect whether files in the stream changed.
I'm guessing you probably want this: https://github.com/floatdrop/gulp-watch
回答4:
This might have more to do with how you're including the partials than anything else - have your @imported the partials into your base sass file?
i.e., does base.scss have
@import 'partial1';
@import 'partial2';
Somewhere in there?
EDIT
Okay I just ran into a similar issue, I ended up just using gulp-newer + looping through an array to generate the gulp tasks. So it looked something like
var sassMain = ['base', 'anotherBase'];
sassMain.forEach(current, function() {
var src = current + '.scss';
return gulp.src(src)
.pipe(newer(destination)
.pipe(plumber())
.pipe(sass())
.pipe(gulp.dest(destination))
});
Not really the most flexible thing in the world (especially with nested directories for the base url), but kind of gets where you want to be. gulp-cached also almost gets where you want to be without this trickery, but has the same won't-compile-partials issue.

I use https://github.com/vigetlabs/gulp-starter as a template with https://github.com/berstend/gulp-sass-inheritance
It works but only with 2 levels of deep
var gulp = require('gulp');
var debug = require('gulp-debug');
var browserSync = require('browser-sync');
var sass = require('gulp-sass');
var sourcemaps = require('gulp-sourcemaps');
var handleErrors = require('../lib/handleErrors');
var autoprefixer = require('gulp-autoprefixer');
var path = require('path');
var cached = require('gulp-cached');
var sassInheritance = require('gulp-sass-inheritance');
var gulpif = require('gulp-if');
var filter = require('gulp-filter');
var duration = require('gulp-duration');
var notify = require('gulp-notify');
var paths = {
src : 'app/styles',
dest: 'grails-app/assets'
}
var isPartial = function (file) {
return /_/.test(file.relative);
}
//set global.isWatching = true on gulp watch
gulp.task('css', function () {
return gulp.src(paths.src)
//.pipe(debug({title: 'before cache:'}))
.pipe(gulpif(global.isWatching, cached('sass')))
//.pipe(gulpif(global.isWatching, debug({title: 'after cache:'})))
.pipe(gulpif(isPartial, sassInheritance({dir: path.join(config.root.src, config.tasks.css.src), debug: false}).on('error', handleErrors))) //,
.pipe(debug({title: 'after sassInheritance:'}))
//.pipe(debug({title: 'after filter:'}))
.pipe(sourcemaps.init())
.pipe(sass()).on('error', handleErrors)
.pipe(debug({title: 'after sass:'}))
//.pipe(notify('Sass compiled <%= file.relative %>'))
.pipe(autoprefixer(config.tasks.css.autoprefixer))
.pipe(sourcemaps.write())
.pipe(gulp.dest(paths.dest))
//.pipe(duration('after sass'))
.pipe(debug({title: 'before browserSync:'}))
.pipe(browserSync.reload({stream: true}))
})

This is an excellent question. I had faced this problem and get rid of that after a huge amount of time. Because there was no such things I found online at that time to get rid of that.
