我正在尝试建立一个github jquery-ui 库 https://github.com/jquery/jquery-ui using grunt，但是运行后npm install我仍然无法按照以下命令运行命令自述文件 https://github.com/jquery/jquery-ui#building-jquery-ui。它只是给出No command 'grunt' found:
james@ubuntu:~/Documents/projects/ad2/lib/jquery-ui$ grunt build
No command 'grunt' found, did you mean:
Command 'grun' from package 'grun' (universe)
grunt: command not found
james@ubuntu:~/Documents/projects/ad2/lib/jquery-ui$ npm ls

我很困惑，请问我错过了什么？
最新版本的 Grunt（撰写本文时为 0.4）不包含命令行工具，您需要单独安装它们。
这是一个好主意，因为这意味着您可以在不同的项目上运行不同版本的 Grunt，但仍然使用简洁的语言grunt命令来运行它们。
因此首先全局安装 grunt cli 工具：
npm install -g grunt-cli
（或者可能sudo npm install -g grunt-cli ).
您可以通过输入来确定它是否有效grunt --version
现在您可以在项目本地安装当前版本的 Grunt。所以从你的项目位置来看......
npm install grunt --save-dev
The save-devswitch 并不是绝对必要的，但这是一个好主意，因为它将在其 package.json devDependencies 部分中将 grunt 标记为仅用于开发的模块。
