javascript - ERR_ABORTED 404(未找到)- Grunt 构建

标签 javascript npm bootstrap-4 gruntjs

所以我正在尝试构建一个 Grunt 运行程序并从 dist 文件夹运行我的项目。

这是我的 Gruntfile.js 代码。

'use strict';

module.exports = function(grunt) {
  // Time how long tasks take. Can help when optimizing build times
  require('time-grunt')(grunt);

  // Automatically load required Grunt tasks
  require('jit-grunt')(grunt, {
    useminPrepare: 'grunt-usemin'
  }); 
  // Define the configuration for all the tasks
  grunt.initConfig({

    sass: {
        dist: {
            files: {
                'css/styles.css': 'css/styles.scss'
            }
        }

  grunt.registerTask('css', ['sass']);
  grunt.registerTask('default', ['browserSync', 'watch']);
  grunt.registerTask('build', [

}

在终端中,我输入 grunt build 并得到它

但是当我运行http://localhost:3000/dist/index.html时我在浏览器控制台中得到了这个。

显然,我的node_module js 文件没有正确缩小到dist 文件夹中。我该如何修复该错误?这是我的repo .

如何修复这个恼人的错误?

谢谢, 西奥

最佳答案

几天前,当我尝试练习时,我遇到了完全相同的问题。 useminprepare 应该只包含index.html,其中usemin 应该处理其他文件。 在 gruntfile.js 中按如下方式编辑 useminprepare,然后它就可以工作:

  useminPrepare: {
        foo: {
            dest: 'dist',
            src: ['index.html']
        }
