我面临gulp-usemin插件问题。当usemin任务运行时，它正在连接和丑化css和js文件，但丑化的 js 文件虽然生成，但不会被重写为 html 文件。我正在分享我的 gulpfile.js 和 index.html 代码。

index.html 转换前

<html>
    <head>
        <!-- build:css build/css -->
        <link rel="stylesheet" href="css/blue.css">
        <link rel="stylesheet" href="css/green.css">
        <link rel="stylesheet" href="css/orange.css">
        <!-- endbuild -->
        <!-- build:js build/js1 -->
        <script src="js/add.js"></script>
        <script src="js/sub.js"></script>
        <script src="js/mul.js"></script>
        <!-- endbuild -->
    </head>
    <body>

        <p class="blue" id="sum"></p>
        <p class="green" id="diff"></p>
        <p class="orange" id="mul"></p>
        <img src="images/1.jpg" width="304" height="228">
        <img src="images/2.jpg" width="304" height="228">

        <script>
        document.getElementById('sum').innerHTML=add(4,4);
        document.getElementById('diff').innerHTML=sub(4,4);
        document.getElementById('mul').innerHTML=mul(4,4);

        </script>
    </body>
</html>

gulpfile.js

var usemin = require('gulp-usemin');
var gulp = require('gulp');
var uglify = require('gulp-uglify');
var minifyHtml = require('gulp-minify-html');
var minifyCss = require('gulp-minify-css');
var jshint = require('gulp-jshint');
var concat = require('gulp-concat');
var rev = require('gulp-rev'),
    notify = require('gulp-notify');

gulp.task('usemin', function() {
  gulp.src('./*.html')
    .pipe(usemin({
      css: [minifyCss(), 'concat'],
      html: [minifyHtml({empty: true})],
      js: [uglify()]
    }))
    .pipe(gulp.dest('build/'));
});

index.html 转换后

//you can see that build/css is generated but build/js is not generated
<html>
    <head>
    <link rel="stylesheet" href="build/css"/>

    </head>
    <body>

    <p class="blue" id="sum"></p>
    <p class="green" id="diff"></p>
    <p class="orange" id="mul"></p>
    <img src="images/1.jpg" width="304" height="228">
    <img src="images/2.jpg" width="304" height="228">

    <script>
    document.getElementById('sum').innerHTML=add(4,4);
    document.getElementById('diff').innerHTML=sub(4,4);
    document.getElementById('mul').innerHTML=mul(4,4);

    </script>
    </body>
</html>

帮助我解决这个问题。提前致谢 。

rev首先，您在通话中缺少js usemin，将您的更改task为：

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

  gulp.src('./*.html')
    .pipe(usemin({
      css: [minifyCss(), 'concat'],
      html: [minifyHtml({empty: true})],
      js: [uglify(), rev()]
    }))
    .pipe(gulp.dest('build/'));

  });

blocks此外， in的最后一个参数gulp-usemin表示 a 的路径file。您应该精确扩展名，以免与目录混淆

<!-- build:css build/style.css -->

<!-- build:js build/js1.js -->

为清楚起见，您还应该在两个不同的块之间放置一个换行符。
