Answer 1

您似乎没有全局安装所需的特权。您可以尝试使用sudo进行安装，也可以（建议）将NPM的默认目录移动到您具有以下读取/写入权限的目录：

在主目录中创建目录，例如~/.npm-global。
运行npm config set prefix '~/.npm-global'
更新您的PATH：export PATH=~/.npm-global/bin:$PATH

https://docs.npmjs.com/resolving-eacces-permissions-errors-when-installing-packages-globally

请注意，尽管您可能只使用sudo，但强烈建议不要这样做。甚至在您发布的错误输出中也是如此：

npm错误！文件及其包含目录的权限，或尝试运行

npm错误！再次以root /管理员身份执行命令（尽管不建议这样做）。

Answer 2

试试看：

以管理员身份登录

sudo su

然后运行

yarn global add @vue/cli

Answer 3

另一个选项是通过运行以下命令向您的用户授予允许在 /usr/local 上进行全局安装的权限：

sudo chown -R $(whoami) /usr/local/lib /usr/local/bin

Answer 4

您没有足够的权限。尝试使用sudo：

sudo npm i -g @vue/cli

Answer 5

您需要通过在命令的第一行写sudo来获得许可

sudo npm i  @vue/cli -g

尝试安装vue / cli时权限被拒绝
