背景： vite打包后的项目 在低版本chrome无法使用

直接打包项目在69版本的chrome上无法加载  报错

解决方法：

使用vite官方推荐的插件 @vitejs/plugin-legacy
1、下载

npm i @vitejs/plugin-legacy -D

2、vite.config.js

import legacy from "@vitejs/plugin-legacy"

plugins: [legacy({targets: ["defaults", "ie >= 11", "chrome 69", "Chrome >= 49"], //需要兼容的目标列表，可以设置多个additionalLegacyPolyfills: ["regenerator-runtime/runtime"],renderLegacyChunks: true,polyfills: ["es.promise.all-settled","es.object.entries","es.symbol","es.array.filter","es.promise","es.promise.finally","es/map","es/set","es.array.for-each","es.object.define-properties","es.object.define-property","es.object.get-own-property-descriptor","es.object.get-own-property-descriptors","es.object.keys","es.object.to-string","web.dom-collections.for-each","esnext.global-this","esnext.string.match-all"],modernPolyfills: ["es.promise.all-settled", "es.object.entries"]})
]

配置好后npm run build:prod打包看下效果

报错如下

修改vite.config.js中 legacy配置项 

 polyfills: ["es.promise.all-settled","es.object.entries",]
modernPolyfills: ["es.promise.all-settled", "es.object.entries"]

重新打包 可以了
