ERROR: Requested resource could not be located. - Grunt build

Hello, I am currently working on setting up a Grunt runner to run my project from the dist folder. Below is the code snippet from my Gruntfile.js:

'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 tasks
  grunt.initConfig({
    // Task configurations here
  });

  // Registering tasks 
  grunt.registerTask('css', ['sass']);
  grunt.registerTask('default', ['browserSync', 'watch']);
  grunt.registerTask('build', [
    'clean',
    'copy',
    'imagemin',
    'useminPrepare',
    'concat',
    'cssmin',
    'uglify',
    'filerev',
    'usemin',
    'htmlmin'
]);
}

After running grunt build in the terminal, I encountered an error while trying to access the project through http://localhost:3000/dist/index.html. The browser console displayed several MIME type errors and failed to load some JavaScript files. This issue seems to stem from incorrect minification of node_module js files into the dist folder.

If you have any insights on how to resolve this error, please feel free to share. You can also find my repository here.

Thank you, Theo

Answer №1

A few days ago, I encountered the same problem while attempting the exercises. Ensure that useminprepare includes only index.html and let usemin handle the other files. Update useminprepare in your gruntfile.js as shown below to resolve the issue:

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