问题描述
我尝试在 Ubuntu 20.04.1 LTS 中安装 yeoman 命令行工具以进行 ASP.NET Core Web 应用程序开发。打字后
npm install -g yo 在终端中，出现错误。
错误描述如下。

解决方法
全局模块安装的 EACCES 错误问题非常普遍，以至于 npm 有 an entire web page dedicated to solving just this issue。
既然你安装的是yeoman，我想这是一台开发机器。在这种情况下，最好的办法可能是安装 node/npm 和 nvm 之类的软件包管理器。
您不想想做但人们通常会建议的一件事是使用 npm 运行 sudo 命令。人们推荐它是因为它简单。但是如果你这样做，你正在安装的任何依赖项的所有生命周期脚本（例如，postinstall）也将作为 root 运行。这可能是很多以 root 身份运行的不受信任的代码。
