Grunt 安装错误/s：“应该使用 -g 安装”

Question

我正在尝试在我的机器上安装 Grunt。我已经阅读了一些tutorials 并关注了installation docs，但我无法让它工作。

CLI 使用此命令安装成功：

sudo npm install -g grunt-cli

当我选择一个本地目录（包含 package.json 和 Gruntfile）和 npm install 时，我看到以下消息：

npm WARN prefer global grunt-cli@0.1.9 should be installed with -g

为什么会这样？我确实使用-g 进行了安装 - 意思是“全球”，我理解。

在这之后，我似乎无法运行 grunt，例如：

$ grunt
-bash: grunt: command not found
$ grunt --version
-bash: grunt: command not found

我该如何解决这个问题？我错过了什么？

这是我的完整日志：

$ sudo npm install -g grunt-cli

Answer 1

当您安装您的语言环境包npm install 时，可能会将包请求grunt-cli 作为依赖项。别担心，这个警告并不意味着它破坏了任何东西。

grunt: command not found 表示 grunt 二进制文件未添加到您的路径中。添加它，你会没事的：https://unix.stackexchange.com/questions/26047/how-to-correctly-add-a-path-to-path

添加的路径应该是终端输出中的这个路径：/Users/tonyMac/.node/bin

在 Bash 中：PATH=$PATH:/Users/tonyMac/.node/bin（如果您在命令行中运行它，则在前面添加 export 命令）。

你不应该使用sudo 来安装包。
如果您使用sudo 安装 node 和 npm 时出现问题。
我看到你使用 OSX，所以相信我，使用 brew 数据包管理器 (http://brew.sh) 安装节点并让它为你处理节点和 npm。

首先删除节点，然后按照说明安装 Brew。 然后你可以输入brew install node，一切都像魅力一样。
