vue-cli-service build : "export 'default' (imported as 'mod') was not found in

[duguangyan]

生产环境构建才出现的问题 vue-cli-service build "export 'default' (imported as 'mod') was not found in
使用 vue-cli-service build --mode xxx 这种就没问题

"unplugin-vue2-script-setup": "^0.6.11",

[duguangyan]

非常感谢支持，将^0.6.11 升级到 ^0.9.3
根据最新 vue cli 文档
// vue.config.js
const ScriptSetup = require('unplugin-vue2-script-setup/webpack').default

module.exports = {
parallel: false, // disable thread-loader, which is not compactible with this plugin
configureWebpack: {
plugins: [
ScriptSetup({ /* options */ }),
],
},
}
修改即可
