Question

我正在尝试使用gulp，当我运行gulp scripts时收到以下错误：

[13:07:39] 'scripts' errored after 1.37 ms
[13:07:39] TypeError: string is not a function
  at Gulp.<anonymous> (/development/tcs/sandbox/frontend/gulpfile.coffee:23:32)

我的gulpfile.coffee

gulp = require 'gulp'

coffee = 'gulp-coffee'
concat = 'gulp-concat'
uglify = 'gulp-uglify'
sourcemaps = require 'gulp-sourcemaps'
clean = require 'gulp-clean'
gutil = 'gulp-util'
debug = 'gulp-debug'

gulp.task 'clean', ->
  gulp.src(bases.dist)
    .pipe(clean())

gulp.task 'scripts', ['clean'], ->
  gulp.src('**/*.coffee')
    .pipe(sourcemaps.init())
    .pipe(coffee({bare: true})).on('error', gutil.log)
    .pipe(uglify())
    .pipe(concat('all.min.js'))
    .pipe(sourcemaps.write())
    .pipe(gulp.dest('public/javascripts/'))

为了找出错误发生的位置，我甚至试过

gulp.task 'scripts', ['clean'], ->
  gulp.src('**/*.coffee').pipe(debug({verbose: true}))

我收到了同样的错误消息。

我做错了什么？

您需要require所有模块，就像您对gulp所做的那样，而不只是指定名称：

gulp = require 'gulp'

coffee = require 'gulp-coffee'
concat = require 'gulp-concat'
uglify = require 'gulp-uglify'
sourcemaps = require 'gulp-sourcemaps'
clean = require 'gulp-clean'
gutil = require 'gulp-util'
debug = require 'gulp-debug'

//Example using the coffee syntax for your scripts task
gulp.task 'scripts', ['clean'], ->
  gulp.src ['**/*.coffee']
    .pipe debug verbose: true

gulp.src TypeError：string不是函数
