小程序基础库: 无
使用框架: Vue 2

复现步骤

按照教程创建项目
Taro init myApp
然后选择vue2
默认模板
Typescript no

npm run dev:weapp
后报错，
npm run build:weapp -- --watch

myApp@1.0.0 build:weapp
taro build --type weapp "--watch"

👽 Taro v3.3.12

Tips: 预览模式生成的文件较大，设置 NODE_ENV 为 production 可以开启压缩。
Example:
$ NODE_ENV=production taro build --type weapp --watch

启动 开发者工具-项目目录 /UserWebStorm/myApp/dist
生成 工具配置 /UserWebStorm/myApp/dist/project.config.json

编译 发现入口 src/app.js
