如何在不出错的情况下安装grunt-cli？

Question

在克里斯科伊尔的帖子的启发下,我决定放弃咕噜咕噜.但是我在设置方面遇到了很大的问题.

首先,我安装了Node.

然后我将package.json文件添加到我的项目根目录,包括:

{
  "name": "example-project",
  "version": "0.1.0",
  "devDependencies": {
    "grunt": "~0.4.1"
  }
}

然后我跑了 npm install

最后,我跑了 npm install -g grunt-cli

它带来了大量的错误:

我认为上述错误是我尝试运行的原因grunt,我只是得到了-bash: grunt: command not found

那里的任何人都知道发生了什么？

Answer 1

所有这一切都是添加'sudo',因为我没有默认安装grunt-cli的权限.运行以下命令并输入密码后,它按预期工作.

sudo npm install -g grunt-cli

希望这有助于某人!

Answer 2

编辑:下面引用的文章很老,指的是v0.3之前的呀!目前,如果npm以sudo权限运行,它将在执行命令之前降级为nobody用户.

根据维护者的说法npm,安装软件包sudo被认为是不好的做法,因为你允许该软件包完全控制你的系统,你不能也不应该信任这些具有root访问权限的软件包.
