当我们执行npm install -g @vue-cli时候会报错：
npm ERR! Invalid tag name “@vue-cli” of package “@vue-cli”: Tags may not have any characters that encodeURIComponent encodes.
npm ERR! A complete log of this run can be found in: /Users/wuwenlu/.npm/_logs/2023-07-30T12_30_33_993Z-debug-0.log

仔细检查我们输入的命令，有误
应该是

npm install -g @vue/cli

再次报错：

npm install -g @vue/cli 
npm ERR! code EACCES
npm ERR! syscall mkdir
npm ERR! path /usr/local/lib/node_modules/@vue
npm ERR! errno -13

再次用管理员输入该命令，发现成功了

sudo npm install -g @vue/cli

验证是否成功安装：

npm list -g
