使用gulp-notify和gulp-plumber处理错误

Question

我希望在以下情况下显示通知:
1.发生错误
2.脚本成功执行后

所有通知实际上都在工作,但即使出现错误,也会始终显示成功通知.

如何确保仅在未发生错误时显示成功通知？

这是我目前的任务:

var gulp = require('gulp');
var sass = require('gulp-ruby-sass');
var rename = require('gulp-rename');
var notify = require('gulp-notify');
var plumber = require('gulp-plumber');
var minifycss = require('gulp-minify-css');
var autoprefixer = require('gulp-autoprefixer');

gulp.task('sass', function(){
   return gulp.src('assets/scss/global.scss')
       .pipe(plumber({errorHandler: notify.onError("Error: <%= error.message %>")}))
       .pipe(sass({ style: 'expanded' }))
       .pipe(autoprefixer())
       .pipe(gulp.dest('assets/css/'))
       .pipe(rename({suffix: '.min'}))
       .pipe(minifycss())
       .pipe(gulp.dest('assets/css/'))
       .pipe(notify({
           title: 'Gulp',
           subtitle: 'success',
           message: 'Sass task',
           sound: "Pop"
       }));
});

gulp.task('watch', function(){
   gulp.watch('assets/scss/**/*.scss', ['sass']);
});

gulp.task('default', ['sass', 'watch']);

我遇到了同样的问题,对我有用的是gulp-if和自定义错误处理程序.基本上,我设置errorFree = false何时抛出错误,然后在结束时显示我gulp-if用来确定是否notify()被调用的成功消息.

使用你的gulpfile:

var gulp = require('gulp');
var sass = require('gulp-ruby-sass');
var rename = require('gulp-rename');
var notify = require('gulp-notify');
var plumber = require('gulp-plumber');
var minifycss = require('gulp-minify-css');
var autoprefixer = require('gulp-autoprefixer');

gulp.task('sass', function(){

    var onError = function(err) {
        notify.onError({
                    title:    "Gulp",
                    subtitle: "Failure!",
                    message:  "Error: <%= error.message %>",
                    sound:    "Beep"
                })(err);

        this.emit('end');
    };

   return gulp.src('assets/scss/global.scss')
       .pipe(plumber({errorHandler: onError}))
       .pipe(sass({ style: 'expanded' }))
       .pipe(autoprefixer())
       .pipe(gulp.dest('assets/css/'))
       .pipe(rename({suffix: '.min'}))
       .pipe(minifycss())
       .pipe(gulp.dest('assets/css/'))
       .pipe(notify({ // Add gulpif here
           title: 'Gulp',
           subtitle: 'success',
           message: 'Sass task',
           sound: "Pop"
       }));
});

gulp.task('watch', function(){
   gulp.watch('assets/scss/**/*.scss', ['sass']);
});

gulp.task('default', ['sass', 'watch']);

在我的gulpfile中,我实际上将每一步都包装起来,gulp-if以便流停止处理.(我没有找到一种方法来阻止流而不会破坏流程,这会使观看IMO失败的目的.)
