gulp - Gulp：对象#

Question

I have cloned a repo with a working gulpfile.js, and now when running gulf on the cloned repo, I received the error

Object #<Object> has no method 'if'

The offending task code: gulp.task('html', ['styles'], function () {

return gulp.src('app/*.html')
  .pipe($.useref.assets({searchPath: '{.tmp,app}'}))
  .pipe($.if('*.css', $.csso()))
  .pipe($.useref.restore())
  .pipe($.useref())
  .pipe(gulp.dest('dist'));
});

I have installed gulp-if and gulp-csso. $ is

var $ = require('gulp-load-plugins')();

Still learning gulp. Not sure where to go from here.

在package.json中， gulp -if未在 devDependencies 下列出。

  "devDependencies": {
      .
      .
      .
      "gulp-if": "^1.2.5",

包括它消除了错误。

每当安装开发依赖项时，我应该加上 --save-dev 以便包自动放在 package.json 中，然后任何克隆都会通过发出 npm install 命令自动获取 package.json 中的所有包。

npm install <package> --save-dev
