安装npm时出错

Question

我是一个初学者，我正在努力学习角，所以我试图安装一个新的项目与角种子。但是当我安装npm时，我得到一个错误，我不知道是从哪里来的。我已经安装了节点。版本是5.5.0。这是我在控制台得到的错误。

问题：您（用户）没有正确的目录权限集。

立即的解决办法是使用sudo运行npm安装，但这可能会给您带来相同的错误或安装不当。

解决方案/建议：更改NPM的默认目录（来自官方文档）

npm uninstall <package-name>  # use sudo if you used it while installation
npm cache verify  # or, npm cache clean for npm version below 5.x.x 

NPM配置集前缀'~/.npm-global'

打开或创建~/.profile或~/.bash_profile文件，并添加一行：

导出路径=~/.npm-global/bin:$path
