我的配置

在vue.config.js

devServer: {
    host: "0.0.0.0",
    port: 8000,
    open: true,
    overlay: {
        warnings: false,
        errors: true
    },
    // before: require('./mock/mock-server.js'),
    proxy: {
        [process.env.VUE_APP_BASE_API]: {
            target: `http://127.0.0.1:9086/`,  //开发环境
            changeOrigin: true,
            pathRewrite: {
                ["^" + process.env.VUE_APP_BASE_API]: ""
            }
        }
    },
    disableHostCheck: true

解决方案：删除两处

1、删除第1处

open: true,
overlay: {
    warnings: false,
    errors: true
},

2、删除第2处

disableHostCheck: true
