javascript - 關於ｇｒｕｎｔ插件browserify設定問題，請求助

<code> browserify: {
      options: {
        transform: ['brfs'],
        debug: true
      },
      debug: {
        files: {'build/test.min.js': 'src/test.js'},  
      }
    }
    </code>

只要加了transform: ['brfs'],就會報錯，去掉就能正常編譯，什麼情況啊？

<code>$ grunt
Running "browserify:debug" (browserify) task
>> TypeError: Cannot read property 'apply' of undefined while parsing file: X:\Users\javascript\Desktop\LEARN\learn_grunt\src\test.js
Warning: Error running grunt-browserify. Use --force to continue.
