Taro 项目 不同平台 打包到不同目录

Taro 项目 不同平台 打包到不同目录

目的：同时编译多套代码，一次修改，同时预览不同平台小程序

在项目根文件夹下 config/index.js 中 新增

const outputRootStrtegy = {
  h5: 'dist_h5',
  weapp: 'dist_weapp',
  alipay: 'dist_alipay',
  swan: 'dist_swan',
  ['undefined']: 'dist'
}
const env = JSON.parse(process.env.npm_config_argv)['cooked'][1].split(':')[1]
const outputRoot = outputRootStrtegy[env]

修改 outputRoot 选项的值
