Answer 1

如果你还没有安装vue-cli

sudo npm install -g @vue/cli

或更新到最新版本

sudo npm update -g @vue/cli

然后创建一个新项目

vue create hello-world

然后选择vue 3项目

您需要使用 npm cache verify 验证您的 npm 缓存，然后尝试安装 vue-cli。如果这不起作用，请尝试使用 npm cache clean --force

完全清除缓存

也可以尝试使用 sudo 权限：sudo npm cache verify 和 sudo npm cache clean --force
