javascript - Windows 7 专业版上的 "Fatal error: Unable to find local grunt."

Question

如果我想启动 grunt，我会收到以下消息:

c:\repositories\kunde_1\themes-projekt_1\projekt_1-responsive\source>grunt
grunt-cli: The grunt command line interface. (v0.1.13)

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

运行 grunt 时你会看到:

C:\Users\dev_user>npm install -g grunt-cli

在用户目录下输入grunt:

Fatal error: Unable to find local grunt.

但是当我进入项目目录时出现相同的信息!

operating system: windows 7 Professional
npm -version: 1.3.5
node --version: v0.10.15

C:\Users\dev_user>npm ls -g
C:\Users\dev_user\AppData\Roaming\npm

  ¦ +-- lodash@2.4.2
  +-- nopt@1.0.10
  ¦ +-- abbrev@1.0.7
  +-- resolve@0.3.1

我设置的环境变量:

变量名:grunt 路径:C:\Users\dev_user\AppData\Roaming\npm\grunt 然后推出新电脑

有没有人知道为什么消息 Fatal error: Unable to find local grunt. coming？

Answer 1

安装 grunt-cli 不会安装 Grunt 任务运行器。 grunt-cli 是允许在同一台机器上同时安装多个版本的 Grunt 的命令行界面。

要安装 grunt，您需要通过以下命令将其全局安装:

npm install -g grunt

或在本地通过以下命令:

npm install grunt

您冷读了 official doc 中的 grunt-cli

来自@Matthew Bakaitis 的注释:

Installing grunt globally is discouraged

It's good practice as grunt-cli loads a global version first (if I recall). If a project was expecting a specific version of grunt, installing globally would break this. Also, if you are depending upon grunt for your builds, why wouldn't you install it as a dependency and list it in package.json? There's a huge assumption that other developers or the target system will have grunt installed globally if you aren't adding as a dependency in package.json. Given the usage situations for grunt, I can't think of many situations where a global install would be better.
