我正在尝试在 nodejs 中安装 yo 和其他一些软件包，但是我不断收到错误。我是节点新手，所以我有点迷失。
我运行的是 Mac OS X 10.10.3。我正在使用的命令是
sudo npm install --global yo
这样做会给我带来以下错误。

一般来说，您不应该使用 sudo 来安装节点模块。
相反，请使用 sudo 修复文件夹权限，以允许您进行全局 npm 安装。
获取 .npm 目录的所有权
sudo chown -R $(whoami) ~/.npm
并具有对 node_modules 目录的写入权限
sudo chown -R $USER /usr/local/lib/node_modules
然后尝试再次运行 npm install 命令without sudo.
