h5配置：

h5: {
    publicPath: '/',
    staticDirectory: 'static',
    devServer: {
      port: 8444,      // 端口号
      host:'localhost',
      open: false,    //配置自动启动浏览器
      proxy:{
              '/open/':{
                target:"http://dev.xxx.com",
                changeOrigin:true,
                secure:false
              }
            }
    },
    postcss: {
      autoprefixer: {
        enable: true,
        config: {
        }
      },
      cssModules: {
        enable: false, // 默认为 false，如需使用 css modules 功能，则设为 true
        config: {
          namingPattern: 'module', // 转换模式，取值为 global/module
          generateScopedName: '[name]__[local]___[hash:base64:5]'
        }
      }
    }
  }

终端运行结果：

./src/pages/index/index.vue
Module Error (from ./node_modules/@tarojs/webpack-runner/node_modules/vue-loader/lib/index.js):


Vue packages version mismatch:

- vue@3.0.0-beta.18 (/Users/chenmeiyuan/Documents/quantong/qkth5TaroV/node_modules/vue/index.js)
- vue-template-compiler@2.6.11 (/Users/chenmeiyuan/Documents/quantong/qkth5TaroV/node_modules/vue-template-compiler/package.json)

This may cause things to work incorrectly. Make sure to use the same version for both.
If you are using vue-loader@>=10.0, simply update vue-template-compiler.
If you are using vue-loader@<10.0 or vueify, re-installing vue-loader/vueify should bump vue-template-compiler to the latest.

用 3.0.2 版本重新创建个就好了。是在微信群里知道的
命令 yarn global add @tarojs/cli@3.0.2
然后创建项目
