[英]Incorrect source maps when using Gulp with source maps plugin
I have recently started using Gulp
as I much prefer the syntax over Grunt
and whilst I like it for the most part I have noticed when using Chrome
or any browser for that matter it tells me the incorrect line mappings when looking in the inspector.我最近开始使用
Gulp
因为我更喜欢Grunt
的语法,虽然我在很大程度上喜欢它,但我注意到在使用Chrome
或任何浏览器时它会告诉我在检查器中查看错误的行映射。
It always tells me the correct file , however it incorrectly tells me the line it is on.它总是告诉我正确的文件,但是它错误地告诉我它所在的行。
What I have found is it seems to have problems with the Sass
nesting ;我发现它似乎与
Sass
嵌套有问题; in that the line number it gives me is the line for where the first parent starts, so for example in the below code:因为它给我的行号是第一个父级开始的行,例如在下面的代码中:
#foo {
.bar {
}
}
If I am trying to inspect an element that has the bar
class, it will tell me it's on line 1
rather than 3
.如果我试图检查具有
bar
类的元素,它会告诉我它在第1
行而不是第3
。
Here is my gulpfile.js
file:这是我的
gulpfile.js
文件:
var gulp = require('gulp');
var concat = require('gulp-concat');
var plumber = require('gulp-plumber');
var sass = require('gulp-sass');
var sourcemaps = require('gulp-sourcemaps');
var autoprefixer = require('gulp-autoprefixer');
gulp.task('scripts', function() {
gulp.src([
'js_dev/jquery.js',
'js_dev/plugins/*.js',
// We have to set the bootstrap lines separately as some need to go before others
'js_dev/bootstrap/alert.js',
'js_dev/bootstrap/collapse.js',
'js_dev/bootstrap/modal.js',
'js_dev/bootstrap/tooltip.js',
'js_dev/bootstrap/popover.js',
'js_dev/bootstrap/tab.js',
'js_dev/bootstrap/transition.js',
'js_dev/scripts.js'
])
.pipe(plumber())
.pipe(sourcemaps.init())
.pipe(concat('scripts.js'))
.pipe(sourcemaps.write('../maps'))
.pipe(gulp.dest('./js'))
});
gulp.task('styles', function() {
gulp.src('scss/**/*.scss')
.pipe(plumber())
.pipe(sourcemaps.init())
.pipe(sass())
.pipe(autoprefixer({
browsers: [
'last 4 Chrome versions',
'last 4 Firefox versions',
'last 4 Edge versions',
'last 2 Safari versions',
'ie >= 10',
'> 1.49%',
'not ie <= 9'
],
cascade: false
}))
.pipe(sourcemaps.write('../maps'))
.pipe(gulp.dest('./css'));
});
gulp.task('watch', function() {
gulp.watch(['scss/**/*.scss', 'js_dev/**/*.js'], ['scripts', 'styles']);
});
gulp.task('default', ['scripts', 'styles']);
The weird issue is that having more than one plugins between gulp-sourcempas
is causing this issue.奇怪的问题是在
gulp-sourcempas
之间有多个插件会导致这个问题。 This is bug and currently I am able to fix is by temporarily removing extra plugins.这是错误,目前我可以通过临时删除额外的插件来修复。 Here is code which most probably will work
这是最有可能工作的代码
gulp.task('styles', function() {
gulp.src('scss/**/*.scss')
.pipe(plumber())
.pipe(sourcemaps.init())
.pipe(sass())
.pipe(sourcemaps.write('../maps'))
.pipe(gulp.dest('./css'));
});
I know this is not real solution, because we need all sorts of other plugins, but this is what works to show correct line numbers.我知道这不是真正的解决方案,因为我们需要各种其他插件,但这是显示正确行号的方法。 You can watch this issue on github to monitor progress in this bug.
您可以在 github 上观看此问题以监控此错误的进度。
I commented out the autoprefixer from between less and source maps write and it shows correct line number now in my case.我从 less 和 source maps write 之间注释掉了 autoprefixer,现在在我的情况下它显示了正确的行号。
gulp.src(['css/custom.less'])
.pipe(sourcemaps.init())
.pipe(less())
// .pipe(autoprefixer({
// cascade: false
// }))
.pipe(sourcemaps.write('./'))
.pipe(gulp.dest('css/'));
