I have gulp-sass installed in another project and works correctly - with the same gulpfile.js which means it must be a problem with in the node_modules folder.
Here is the gulpfile.js for reference:
var gulp = require('gulp');
var sass = require('gulp-sass');
gulp.task('e', function(){
gulp.src('app/admin/assets/sass/*.scss') // ## Not working
.pipe(sass())
.pipe('dist/admin/assets/css');
});
gulp.task('default', ['e'], function(){
console.log('Gulp tasks started!');
});
How can I fix this problem?
Your destination should be written like :
gulp.task('e', function(){
gulp.src('app/admin/assets/sass/*.scss') // ## Not working
.pipe(sass())
.pipe( gulp.dest('dist/admin/assets/css') );
});
In order to pipe properly to your destination folder.

I have created a gulpfile.js file for a project I'm building. When I try to run it, I get this error.

Also, you will want to switch to the plugin gulp-dart-sass instead of gulp-sass. It supports more recent features like #use for example.
I'm new with js, node and all things related.
I'm trying to set up a front end development environment from scratch, using gulp, bower, browser sync, and other plugins.
I'm almost done, it's working in some way, except for a couple of details I can't resolve because I'm not sure if it's something in the code syntax or the order of the functions executed in my gulpfile.js file, or because the plugins are not being used correctly. I have already tried to change the order of them, change some path, etc with no results.
Now I'm experiencing the following issues:
The main.scss needs to be saved two times before see the changes reflected in the browser.
When I run gulp in the console this is what I receive (these errors are new and appeared after a minor change proposed by Poeta in his answer, which helped me a lot.

Update about previous problem: The following was resolved thanks to Bruno Poeta's answer.

Note: the line 526 doesn't exist since it is generated by the gulp-inject plugin. These are the last lines in the main.css file, line 520 and 521:
// inject:app
// endinject
The error as you may have noticed is in your styles task. The problem is that you are importing all .scss files, including main.scss itself. That is your loop, right there. Remove main.scss from the files that should be injected, like this:
gulp.task('styles', function(){
var injectAppFiles = gulp.src(['!src/styles/main.scss', 'src/styles/*.scss'], {read: false});
// ...
It should work right now.
So i got this very simple gulp task :
var gulp = require('gulp');
var source = require('vinyl-source-stream');
var browserify = require('browserify');
gulp.task('browserify', function() {
return browserify({ entries: ['main.js'] })
.bundle()
.pipe(source('bundle.js'))
.pipe(gulp.dest('dist'));
});
gulp.task('default', ['browserify']);
Which is supposed to simply browserify my main.js to bundle.js and then store it in a dist folder.
Problem is, it seems that gulp doesnt like it when parsing HTML because i got this error :
events.js:85
throw er; // Unhandled 'error' event
^ Error: Parsing file C:\Dev\react_wkspc\main.js: Unexpected token (5:2)
my main.js is also very basic :
var React = require('react');
var ReactDOM = require('react-dom');
ReactDOM.render(
<h1>First test of react!</h1>,
document.getElementById('container');
);
and the error seems to come from this line <h1>First test of react!</h1>, which is, i believe, the proper way to uses React because it is the same script as the official React doc
i also tried with babelify and this script :
var gulp = require('gulp');
var source = require('vinyl-source-stream');
var babelify = require('babelify');
var browserify = require('browserify');
gulp.task('browserify', function () {
browserify({
entries: 'main.js',
extensions: ['.js'],
debug: true
})
.transform(babelify)
.bundle()
.pipe(source('bundle.js'))
.pipe(gulp.dest('dist'));
});
gulp.task('default', ['browserify']);
and got the same error
SyntaxError: C:/Dev/react_wkspc/main.js: Unexpected token (5:2)
The missing steps from what I can read is
add babelify
make sure that you also have the proper babel presets installed such that your source can be parsed correctly.
Here is an example from a project of mine, with b being browserify
function bundleShare(b, output) {
return b
.transform(babelify.configure({
presets: ["es2015", "react"]
}))
.bundle()
.pipe(source(output))
.pipe(gulp.dest('./wwwroot/assets'));
}
In my package json I have the following dev dependencies
"
babel-preset-es2015": "^6.3.13",
"babel-preset-react": "^6.3.13",
"babelify": "^7.2.0",
I've been trying to improve my standard gulpfile to notify when errors occur when compiling scss and JS.
SCSS Issue
I have it working for SCSS, it throws the error in terminal, makes a noise and doesn't stop gulp running - which is great.
Strangely, my styles used to compile when I ran gulp, but now I need to save one of the .scss files to start gulp (again this is good, but I want it to compile on running gulp).

JS Issue
I'm also trying to notify of errors and exactly where they're coming from in for the JS too (and also prevent gulp from stopping when an error occurs). Tried adding gulp-jshint, but it doesn't seem to be working. It flags the error with a noise etc... but doesn't tell me which of the concatenated files the error is located in. It just says:
Error in plugin 'gulp-uglify'

gulp.task('default', ['scripts', 'watch']);
livereload.listen();
(My JS isn't great, so please bear with me )
Update
I've now managed to plumb a JS error through to terminal, but not sure how to report what the error actually is, which file the error is coming from and which line? Obviously need to replace the console.log with some variables but not sure how to achieve this?
gulp.task('scripts', function() {
return gulp.src(['./js/script.js'])
.pipe(include())
.pipe(plumber(
//{errorHandler: errorScripts};
function() {
console.log('There was an issue compiling scripts');
this.emit('end');
}
))
.pipe(concat('script-dist.js'))
//.pipe(stripDebug())
//.pipe(jshint())
.pipe(uglify())
.pipe(gulp.dest('./js/'))
.pipe(livereload());
});
Styles not running answer:
When running you default task, your styles are not compiled, because you do this:
gulp.task('default', ['styles', 'watch']);
gulp.task('default', ['scripts', 'watch']);
Basically what you're doing here is overwriting your default task with a new one.
This can be overcome easily by combining the two:
gulp.task('default', ['scripts', 'styles', 'watch']);
Error notification in console answer:
You should do the jshinting before concatenation, or else you will get error reporing on the concatenated file (script-dist.js).
You should change your gulpfile to:
gulp.task('scripts', function() {
return gulp.src(['./js/script.js'])
.pipe(include())
.pipe(plumber(
//{errorHandler: errorScripts};
function() {
console.log('There was an issue compiling scripts');
this.emit('end');
}
))
.pipe(jshint())
.pipe(concat('script-dist.js'))
.pipe(stripDebug())
.pipe(uglify())
.pipe(gulp.dest('./js/'))
.pipe(livereload());
});
That should do the trick ;-)
I am using babel to transpile my es6 code. I'm also using gulp to do the tasks. My gulpfile.js looks like the following :
var gulp = require('gulp'),
es6Path = './src/*.js',
browserify = 'browserify',
babelify = require('babelify'),
source = require('vinyl-source-stream');
gulp.task('build', function () {
return browserify({entries: './src/script.js', extensions: ['.js'], debug: true})
.transform(babelify)
.bundle()
.pipe(source('bundle.js'))
.pipe(gulp.dest('dist'));
});
gulp.task('watch', ['build'], function () {
gulp.watch(es6Path, ['build']);
});
gulp.task('default', ['watch']);
But when I try to run gulp , I get this error :
Starting 'build'...
'build' errored after 100 μs
TypeError: string is not a function
Any idea why this happens ?
You set browserify to string 'browserify' then try to call it as a function. You need to require('browserify').
