为什么我的 vue.config.js 文件不起作用？

Question

我想部署我的应用程序，为此我需要 vue.config.js 文件作为目标 URL。但是我放在这个文件中的所有内容（我必须自己创建）都不起作用。不是构建的输出目录或 devServer 内的代理。有人遇到过同样的问题并得到解决吗？请帮我

const path = require('path')

module.exports = {
    outputDir: path.resolve(__dirname, '../server/public'),
    devServer: {
      proxy: {
        '/api': {
           target: 'http://localhost:8081/'
        }
     }
    }
  };

您似乎正在使用旧的vue-cli并使用vue init webpack <project-name>.

由于它全部演变成vue cli 3，旧的 vue-cli 已被弃用，我们现在使用 @vue/cli 来vue create <project-name>搭建项目。

你使用旧的方式是完全可以的（我有时仍然这样做），并且当你使用 @vue/cli 时， vue.config.js 是你的项目的全局配置文件。在这里查看更多相关信息。

对于使用 vue-cli 以及使用npm init命令搭建的项目中的 webpack 配置，请检查项目文件夹根目录中的/build目录。
