通过命令行安装Grunt时遇到问题

Question

我正在尝试安装Grunt命令行，并且在安装时遇到困难。我非常密切地关注克里斯科伊尔的演练，并没有看到我出错的地方。我的项目名称为“瑞安”这里是我的package.json：

{ 
    "name": "ryan", 
    "version": "0.1.0", 
    "devDependencies": { 
    "grunt": "~0.4.2" 
    } 
} 

咕噜似乎，node_modules安装到项目文件夹中安装的罚款。但是，一旦我输入“npm install -g grunt-cli”，它似乎失败了。任何解决方案：

我的终端：

ryans-mbp:ryan rynslmns$ npm install -g grunt-cli

这是因为您使用不具有权限的用户写入的Node.js安装在安装文件夹。

要安装你需要与运行：sudo npm install grunt-cli -g

但我强烈建议，而不需要运行sudo的节点/ NPM。有很多种方法，这里是安装的node.js无需sudo访问的方式：

echo 'export PATH=$HOME/local/bin:$PATH' >> ~/.bashrc 
. ~/.bashrc 
mkdir ~/local 
mkdir ~/node-latest-install 
cd ~/node-latest-install 
curl http://nodejs.org/dist/node-latest.tar.gz | tar xz --strip-components=1 
./configure --prefix=~/local 
make install 
curl https://npmjs.org/install.sh | sh
