為什么grunt無法依賴imagemin？

Question

我正在使用節點版本0.12.2和npm版本3.3.6。 我正在使用yeoman工具創建角度應用程序。 當我運行grunt時，它在imagemin依賴關系中終止。 我嘗試了命令npm install -g grunt-contrib-imagemin和npm install imagemin imagemin.Still我npm install imagemin遇到相同的錯誤：

Execution Time (2015-12-27 19:17:59 UTC)
    loading tasks          87ms  ▇▇ 3%
    loading grunt-svgmin     2s  ▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇ 75%

    Total 2.6s
        Warning: Running "imagemin:dist" (imagemin) task
    Fatal error: Cannot read property 'contents' of undefined
     Aborted due to warnings.

這是我的package.json：

  "private": true,
  "devDependencies": {
    "grunt": "^0.4.5",
    "grunt-angular-templates": "^0.5.7",

  },
  "engines": {

  },
  "scripts": {

}

任何幫助，將不勝感激。
