gulp.js - dest.on不是一个函数

Question

我试图编译我styles.scss有gulp-sass,当我收到以下错误:

[09:48:49] Starting 'e'...
[09:48:49] 'e' errored after 2.35 ms
[09:48:49] TypeError: dest.on is not a function

我已gulp-sass安装在另一个项目中并正常工作 - 同样gulpfile.js意味着它必须是node_modules文件夹中的问题.

以下是gulpfile.js供参考:

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!');
});

我该如何解决这个问题？

您的目的地应该写成:

gulp.task('e', function(){
  gulp.src('app/admin/assets/sass/*.scss') // ## Not working
    .pipe(sass())
    .pipe( gulp.dest('dist/admin/assets/css') );
});

为了正确管道到您的目标文件夹.
