vue-cli打包生产环境部署到服务器上后代码报错。

Question

1.在开发环境下一切正常，打包完成后部署到服务器上之后访问报错，报错如图一

2.相关的资源文件都是正常引入的，页面也能显示一部分。我猜应该是代码哪里有问题，前几次打包也可以正常访问。后面这次修改并没有更改打包配置文件。望大佬指教

3.以下是配置文件代码

'use strict'
// Template version: 1.1.3
// see http://vuejs-templates.github.io/webpack for documentation.

const path = require('path')


module.exports = {
  build: {
    env: require('./prod.env'),
    index: path.resolve(__dirname, '../' + process.env.dist + '/index.html'),
    assetsRoot: path.resolve(__dirname, '../' + process.env.dist),
    assetsSubDirectory: 'assets',
    assetsPublicPath: '/',
    productionSourceMap: true,
    // Gzip off by default as many popular static hosts such as
    // Surge or Netlify already gzip all static assets for you.
    // Before setting to `true`, make sure to:
    // npm install --save-dev compression-webpack-plugin
    productionGzip: false,
    productionGzipExtensions: ['js', 'css'],
    // Run the build command with an extra argument to
    // View the bundle analyzer report after build finishes:
    // `npm run build --report`
    // Set to `true` or `false` to always turn it on or off
    bundleAnalyzerReport: process.env.npm_config_report
  },
  dev: {
    env: require('./dev.env'),
    port: process.env.PORT || 8080,
    autoOpenBrowser: true,
    assetsSubDirectory: 'assets',
    assetsPublicPath: '/',
    proxyTable: {},
    // CSS Sourcemaps off by default because relative paths are "buggy"
    // with this option, according to the CSS-Loader README
    // (https://github.com/webpack/css-loader#sourcemaps)
    // In our experience, they generally work as expected,
    // just be aware of this issue when enabling this option.
    cssSourceMap: false
  }
}

prod.env.js生产环境变量

'use strict'
/*  根据不同命令，配置不同的项目 */
if (!process.env.url) {
  if (process.env.npm_lifecycle_event === 'build-2mm') {
    process.env.project = '2mm'
    process.env.url = 'http://seller.2mm.cn'
    process.env.api = 'http://testuapi.2mm.cn'
    process.env.dist = 'dist-2mm'
    process.env.logout = 'http://www.2mm.cn/user/logout'
  } else if (process.env.npm_lifecycle_event === 'build-go2') {
    process.env.project = 'go2'
    process.env.url = 'http://seller.go2.cn'
    process.env.api = 'http://testuapi.go2.cn'
    process.env.dist = 'dist-go2'
    process.env.logout = 'http://www.go2.cn/user/logout'
  } else if (process.env.npm_lifecycle_event === 'build-3e3e') {
    process.env.project = '3e3e'
    process.env.url = 'http://seller.3e3e.cn'
    process.env.api = 'http://testuapi.3e3e.cn'
    process.env.dist = 'dist-3e3e'
    process.env.logout = 'http://www.3e3e.cn/user/logout'
  }
}
module.exports = {
  NODE_ENV: '"production"',
  Project: '"' + process.env.project + '"',
  Url: '"' + process.env.url + '"',
  Api: '"' + process.env.api + '"',
  Dist: '"' + process.env.dist + '"',
  Logout: '"' + process.env.logout + '"'
}

Answer 1

问题已经找到了，是因为运维拉去代码的时候并没有把上个版本的删干净再拉，而是直接覆盖所导致的。问题确实很奇怪，让他删完之前的文件再拉取代码就没问题了。

Answer 2

会不会因为本地和线上环境不同造成的错误，比如windows和linux，一个大小写不敏感一个敏感。

Answer 3

你项目中是使用了bootstrap对吧？ 你是怎么引入并使用的？

Answer 4

process.env.url？？
打包以后，你运行在什么环境下，node ? 还是 apache或nginx?

如果是后两者 哪来的process.env
