为什么Gulp指南针会抛出TypeError：Windows 7环境中的dest.on不是函数

Question

I have installed gulp and some other packages in the root directory of my project in Visual Studio, Windows 7. I'm find that whenever I run the command gulp watch or gulp compass watch I get the following error:

C:\MyProject>gulp compass watch
[11:03:53] Using gulpfile C:\MyProject\gulpfile.js
[11:03:53] Starting 'compass'...
[11:03:53] 'compass' errored after 6.09 ms

Here is my gulpfile.js:

// Include Our Plugins
var gulp = require('gulp');
var sass = require('sass');
var compass = require('compass');
var rename = require('gulp-rename');

var config = {
    bootstrapDir: 'node-modules/bootstrap-sass',
    publicDir: 'Content',
};
// Pipe boostrap-sass to main css directory
gulp.task('css', function() {
     gulp.src('Content/scss/bootstrap-app.scss')
    .pipe(sass({
        includePaths: [config.bootstrapDir + '/assets/stylesheets'],
}))
.pipe(gulp.dest(config.publicDir + '/css'));
});

// Compile with Compass
gulp.task('compass', function() {
  return gulp.src('Content/scss/*.scss')
        .pipe(compass({
        //  config_file: 'node_modules/compass/test/config.rb',
          css: 'css',
          sass: 'scss'
    }))
    .pipe(gulp.dest('Content/css'));
});

// Watch Files For Changes
gulp.task('watch', function() {
    gulp.watch('Content/scss/*.scss', ['compass']);
});

// Default Task
gulp.task('default', ['compass', 'watch']);

Any help on this much appreciated. Thanks,

您需要安装并且需要gulp-compass ，而不是compass 。
