Javascript Grunt返回所有任务的错误

Grunt返回所有任务的错误“未找到目标”或“未找到任务”。 另外，grunt--help不会显示某些可用的任务，例如“构建”和“测试”任务

此配置以前似乎工作正常。但它没有改变（git确保了这一点）

怎么了

这是我的Grunfile.js：

module.exports = function(grunt) {
  require('time-grunt')(grunt);
  require('load-grunt-tasks')(grunt);

使用npm安装的所有依赖项。

您在哪里加载任务？在Grunt配置和执行任务之前，需要使用NPM加载任务。看

下面是Grunt站点的一个示例：

module.exports = function(grunt) {

  // Project configuration.
  grunt.initConfig({
    pkg: grunt.file.readJSON('package.json'),
    uglify: {
      options: {
        banner: '/*! <%= pkg.name %> <%= grunt.template.today("yyyy-mm-dd") %> */\n'
      },
      build: {
        src: 'src/<%= pkg.name %>.js',
        dest: 'build/<%= pkg.name %>.min.js'
      }
    }
  });

  // Load the plugin that provides the "uglify" task.
  grunt.loadNpmTasks('grunt-contrib-uglify');

  // Default task(s).
  grunt.registerTask('default', ['uglify']);

};

module.exports=函数（grunt）{
//项目配置。
grunt.initConfig({
pkg:grunt.file.readJSON（'package.json'），
丑陋的：{
选项：{
横幅：'/*！*/\n'
},
建造：{
src:'src/.js'，
dest:'build/.min.js'
}
}
});
//加载提供“丑”任务的插件。
grunt.loadNpmTasks（“grunt-contrib-uglify”）；
//默认任务。
registerTask（'default'，['uglify']）；
};

require（'load-grunt-tasks'）（grunt）加载mypackage.json中列出的所有任务。@WlodzislavK。嗯，您是否运行了NPM安装？是否确实存在模块？…添加

--verbose

标志是否提供了指向问题根源的任何其他详细信息？

module.exports = function(grunt) {

  // Project configuration.
  grunt.initConfig({
    pkg: grunt.file.readJSON('package.json'),
    uglify: {
      options: {
        banner: '/*! <%= pkg.name %> <%= grunt.template.today("yyyy-mm-dd") %> */\n'
      },
      build: {
        src: 'src/<%= pkg.name %>.js',
        dest: 'build/<%= pkg.name %>.min.js'
      }
    }
  });

  // Load the plugin that provides the "uglify" task.
  grunt.loadNpmTasks('grunt-contrib-uglify');

  // Default task(s).
  grunt.registerTask('default', ['uglify']);

};
