javascript之尝试安装 vue/cli 时权限被拒绝_编程设计

我正在尝试在我的项目中安装 vue cli，但出现该错误，我是新的 MacOs 用户。希望你能帮我修复它并在我的项目中安装 vue cli。

Circus-MBP:TodoApp circus4$ npm i  @vue/cli -g

请您参考如下方法:

您似乎没有全局安装所需的权限。您可以尝试使用 sudo 安装或(推荐)将 NPM 的默认目录移动到您具有读/写权限的目录:

在您的主目录中创建目录，比如 ~/.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，虽然您可能只使用 sudo，但强烈建议不要这样做。它甚至在您发布的错误输出中这样说:

npm ERR! permissions of the file and its containing directories, or try running

npm ERR! the command again as root/Administrator (though this is not recommended).
