我正在尝试在我的计算机上安装 Grunt。我读过一些tutorials并关注installation docs ，但我无法让它工作。
CLI 使用以下命令安装正常:
sudo npm install -g grunt-cli
当我选择本地目录(包含 package.json 和 Gruntfile)和 npm install 时，我看到以下消息:
npm WARN prefer global <a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="543326213a207937383d14647a657a6d" rel="noreferrer noopener nofollow">[email protected]</a> should be installed with -g
为什么会发生这种情况？我确实使用 -g 安装 - 意思是“全局”，我明白。
此后，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

最佳答案
您不应使用 sudo 来安装软件包。
如果您使用sudo，则在安装node和npm时会出现问题。
我看到您使用 OSX，所以请相信我，使用 brew 数据包管理器 ( http://brew.sh ) 安装 Node ，并让它为您处理 Node 和 npm。
先删除 Node ，然后按照说明安装 Brew。
然后，您只需输入 brew install node ，一切就会变得非常顺利。
