坑

1、SyntaxError，代码编写正确

具体报错

VM33 WAService.js:2 MiniProgramError
missing ) after argument list
SyntaxError: missing ) after argument list

页面【pages/me/index]错误:
 Error: module "pages/me/index.js" is not defined
    at require (VM33 WAService.js:2)
    at <anonymous>:120:9
    at doWhenAllScriptLoaded (<anonymous>:155:21)
    at Object.scriptLoaded (<anonymous>:175:5)
    at Object.<anonymous> (<anonymous>:200:22)

原因：config文件夹下的配置文件导出错误
解决：导出使用 module.exports替换module.exports

module.exports = {
  env: {
    NODE_ENV: '"development"'
  },
  defineConstants: {
      SERVER_URL: "http://192.168.0.16:8080",
    APP_KEY: "APP_KEY",
    THEME_COLOR: "#36C38A"
  },
  mini: {},
  h5: {}
}

为了保险起见，SERVER_URL的可以再用’'包裹，如：SERVER_URL: '"http://192.168.0.16:8080"'

2、引入taro-ui时出现找不到 “./style/index.scss”

具体报错

Error: Cannot find module 'taro-ui/dist/style/index.scss'
    at webpackMissingModule (VM89 app.js:24)
    at Object../node_modules/babel-loader/lib/index.js!./src/app.ts (VM89 app.js:24)
    at __webpack_require__ (bootstrap:79)
    at Module../src/app.ts (app.scss:1)
    at __webpack_require__ (bootstrap:79)
    at checkDeferredModules (bootstrap:45)
    at Array.webpackJsonpCallback [as push] (bootstrap:32)
    at VM89 app.js:7
    at require (VM71 WAService.js:2)
    at <anonymous>:3:7

解决：安装 3.0.0-alpha 或 3.0.0-alpha.3 版本的 taro-ui
命令：npm install taro-ui@3.0.0-alpha.3 -D

后期遇到的坑会持续更新
