安装依赖文章源自浅海拾贝-https://blog.terwergreen.com/babel-run-nodejs-19pblp.html

yarn add @babel/core @babel/cli @babel/node @babel/preset-env -D

~~或者全局安装~~文章源自浅海拾贝-https://blog.terwergreen.com/babel-run-nodejs-19pblp.html

yarn global add @babel/core @babel/cli @babel/node @babel/preset-env

注意：全局安装需要把yarn的全局目录添加到Windows的path，查找path命令如下文章源自浅海拾贝-https://blog.terwergreen.com/babel-run-nodejs-19pblp.html

yarn global bin

~~不建议全局安装，很多时候以来都成问题~~文章源自浅海拾贝-https://blog.terwergreen.com/babel-run-nodejs-19pblp.html
