Answer 1

你正面临文件权限的问题。

npm 的-g 参数表示“全局”，它会将这些文件安装在系统目录中，特别是在您的计算机/usr/local/lib/node_modules 中，其中所有者可能是root 并具有权限rwxr-xr-x，表示不是root的人没有写权限。

那么，你可以使用sudo来获取这个权限，或者就像NPM modules won't install globally without sudo说的，在你有权限的路径中设置npm前缀：

$ npm config set prefix '~/.npm-packages'

Answer 2

所有你需要做的就是在它之前运行相同的命令 sudo，

$ sudo npm install -g @vue/cli

系统会提示您输入管理员密码。
