gruntjs - 咕噜 fatal error : Unable to find local grunt in Yeoman

Question

我安装了 yeoman 并启动了官方文档中提供的示例。 我完成了建议的操作

    yo webapp 
    bower install underscore  
    grunt

运行 grunt 后我收到消息

    grunt-cli: The grunt command line interface. (v0.1.9)

    Fatal error: Unable to find local grunt.

    If you're seeing this message, either a Gruntfile wasn't found or grunt
    hasn't been installed locally to your project. For more information about
    installing and configuring grunt, please see the Getting Started guide:

    http://gruntjs.com/getting-started

请注意，grunt 已安装

    npm install -g grunt-cli

和

    npm install -g grunt

yo 已在我运行命令的项目根目录中生成了 Gruntfile.js。
package.json 也已生成:

    "name": "testyo",
    "version": "0.0.0",
    "dependencies": {},
    "devDependencies": {
      "grunt": "~0.4.1",
      "grunt-contrib-copy": "~0.4.1",
      "grunt-contrib-concat": "~0.1.3",
      "grunt-contrib-coffee": "~0.6.5",
      "grunt-contrib-uglify": "~0.2.0",
      "grunt-contrib-compass": "~0.2.0",
      "grunt-contrib-jshint": "~0.4.1",
      "grunt-contrib-cssmin": "~0.6.0",
      "grunt-contrib-connect": "~0.2.0",
      "grunt-contrib-clean": "~0.4.0",
      "grunt-contrib-htmlmin": "~0.1.3",
      "grunt-contrib-imagemin": "~0.1.3",
      "grunt-contrib-watch": "~0.4.0",
      "grunt-rev": "~0.1.0",
      "grunt-autoprefixer": "~0.1.20130516",
      "grunt-usemin": "~0.1.10",
      "grunt-mocha": "~0.3.0",
      "grunt-open": "~0.2.0",
      "grunt-svgmin": "~0.1.0",
      "grunt-concurrent": "~0.1.0",
      "matchdep": "~0.1.1",
      "connect-livereload": "~0.2.0"
    },
    "engines": {
      "node": ">=0.8.0"
    }

另外。从根目录

    grunt --version
    grunt-cli v0.1.9

这确认 grunt 可以在每个目录中运行。
有什么想法吗？

Answer 1

经过一些快速研究后，我意识到，来自 grunt documentation ，该 grunt 必须安装在项目中。我通过运行做到了这一点:

    sudo npm install grunt --save-dev

现在 grunt 可以工作了。

我还需要运行:

    npm install

以便加载所有依赖项。

这解决了我的问题。说实话，我以为 yeoman 会自动完成最后两个步骤。
