简要概述

安装Vue CLI时出现的错误内容和解决方法的备忘录。

顺便提一下，笔者使用的电脑环境是macOS。

导致这种情况的因素是什么？

权限被拒绝，这是因为安装目录的权限错误直接导致的。

由于使用npm的-g选项进行”全局安装”，推测是登录用户在没有对整个计算机具有访问权限的情况下进行了安装操作。

即使登录用户拥有管理员权限，由于计算机的设置，系统有时会默认不轻易接受可能对整个系统产生影响的命令。

应对方法·解决方案

请明确授予管理员权限后进行安装。

看起来成功了，所以确认一下命令是否正常运行。

# バージョン確認コマンド

由于命令成功执行，错误处理已完成。现在可以无问题地使用了。
