寫入第一個Grunt插件 - 即使grunt.registerMultiTask（）名稱正確，也找不到任務

Question

我寫了第一個grunt插件，但由於某種原因未找到任務。我不知道爲什麼......因爲名字與grunt.registerMultiTask是一對一的。我將任務的名稱更改爲apple，以便簡化調試。

任務從node_modules/grunt-testem-config-maker/tasks/apple.js文件「

module.exports = function(grunt) { 

    // Please see the Grunt documentation for more information regarding task 
    // creation: http://gruntjs.com/creating-tasks 

    grunt.registerMultiTask('apple', 'Purpose: None concatenated file use in testem with automated testem.json configuration generation. Reads index.html, scrapes <script> tags, and inserts filenames in src_files.', function() { 
    // Merge task-specific and/or target-specific options with these defaults. 
    var options = this.options({ 
     indexHtml: '/home/one/simple-load-balancer-service/lbs/app/static/index.html', 
     punctuation: '.', 
     separator: ', ', 
     configFile: 'testem.json', 
     launch_in_dev: ["PhantomJS"], 
     launch_in_ci: ["PhantomJS"], 
     url: "http://10.1.2.11:7357", 
     src_files_ignore: "spec-bower-vendor/angular-core/" 
    }); 

    readFile(options.indexHtml, 'utf8').done(function (indexHtml) { 
     var fileList = getFileNames(indexHtml); 
     dumpToFile(fileList); 
    }, function (err) { 
     console.log("Doh! Couldn't read index.html to get files for testem!") 
    }); 
    }); 
}; 

var fs = require('fs'); 
var Q = require('q'); 
var cheerio = require('cheerio'); 

var readFile = Q.nfbind(fs.readFile); 
var writeFile = Q.nfbind(fs.writeFile) 

function dumpToFile(fileList) { 
    var destFile = "file-list.txt"; 
    var output = 'module.exports = ' + JSON.stringify(fileList,null,'\t'); 
    writeFile(destFile, output) 
    .done(function(err) { 
     if (err) { 
     console.log(err); 
     } else { 
     console.log("saved"); 
     } 
    }); 
} 

function getFileNames(indexHtml) { 
    var bower_files = []; 
    var js_files = []; 
    var BOWER_ROOT = 'app/'; 
    var JS_ROOT = 'app/scripts/'; 
    var BOWER_DIR = "bower_components"; 

    var $ = cheerio.load(indexHtml); 
    var scriptTags = $('html').find('script'); 
    scriptTags.map(function(element) { 
    if (element) { 
     element = scriptTags[element].attribs.src; 
     if (element.split('/')[1] === BOWER_DIR) { 
     element = element.replace("../", BOWER_ROOT); 
     bower_files.push(element); 
     } else { 
     element = JS_ROOT + element; 
     js_files.push(element); 
     } 
    } 
    }); 
    return { 
    bower_files: bower_files, 
    js_files: js_files 
    }; 
}

我Gruntfile.js文件：

module.exports = function(grunt) { 
    require('load-grunt-tasks')(grunt); 
    grunt.initConfig({ 
     apple: { 
     options: { 
      indexHtml: "sss" 
     } 
     } 
    }); 
    grunt.registerTask('default', 'start server', function() { 
     //grunt.task.run('express'); 
     grunt.task.run('apple'); 
    }); 
}

輸出：

one@localhost ~/simple-load-balancer-service/lbs $ grunt apple

Aborted due to warnings.

我修改我的任務文件中的node_modules目錄。但npm緩存目錄正在被讀取，並沒有反映所做的更改。
