2、错误原因

在调用微信小程序中的模块，生成二维码；需要用到wx-server-sdk模块，但是这个模块没有安装

const cloud = require('wx-server-sdk')
        cloud.init()
        exports.main = async (event, context) => {
          try {
            const result = await cloud.openapi.wxacode.createQRCode({
              path: 'page/index/index',
              width: 430
            })
            console.log(result)
            return result
          } catch (err) {
            console.log(err)
            return err
          }
        }

3、解决办法

使用npm安装wx-server-sdk

npm install --save wx-server-sdk@latest

但是问题是，本地微信小程序项目下没有package.json文件，无法安装

Administrator@USER-0GUONPPBHK MINGW64 /f/wio
    $ npm install --save wx-server-sdk@latest
    
    > protobufjs@6.8.8 postinstall F:\wio\node_modules\protobufjs
