搜索了一段时间后，我发现此命令适用于人sudo npm uninstall -g npm，但是在尝试卸载npm时遇到完全相同的错误。

那么如何更新我的npm？

您正在使用的Node.js版本5.3.0严重过时。您已经安装了最新的npm版本（5.5.1），但这是包管理器，并且它不会在这样一个过时的Node.js上运行，因为它依赖于稍后添加的功能。正如您在错误消息中看到的那样，它使用Buffer.alloc，该版本中不存在。

您需要升级Node.js（运行时），而不是npm（包管理器）。当您运行npm update -g时，它只会更新由npm安装的软件包。

看起来你已经用Homebrew安装了Node.js，所以你可以使用以下命令升级它：

brew update
brew upgrade node

无法更新节点：npm不支持Node.js v5.3.0
