项目打包时出现了这种问题,是一个叫core-js的包出了问题;
解决方法是
1.是版本的问题,要重新install一下
npm install core-js@3 --save
# or
npm install core-js@2 --save
2.也有人给出了这种方法:(我用这种方法还是出现了些问题,如果上面那种方式没有解决你的问题,你可以再试试这种方式;或者两种方式都用,未尝不可。)
presets: [ [ "@vue/app", { useBuiltIns: "entry" } ] ]
详情参考这里:
useBuiltIns
core-js module error

你可能出现过这种问题,没有直接忽视;

.....后面还有很多。
你看可以重新 install 一下找不到的那个插件();或者直接npm install 全部重新安装一下。因为我看到package.json中是有这些模块的,安装cli的时候他是已经安装好了的,不知道为什么,现在找不到了。重新npm install 一下就好了。
