Vue CLI 3 应用程序：NPM 构建中未捕获的语法错误

Question

我有一个使用 Vue CLI 3 创建的 Vue.js 应用程序。当我运行 npm run serve 时它启动正常，但是当我尝试构建它时出现错误用于部署 ( npm run build ).

错误是Uncaught SyntaxError: Unexpected token <。

我发现了几个类似的问题，并且大多数建议的解决方案都围绕着 babel。这是我的 babel.config.js:

module.exports = {
  presets: [
    '@vue/app'
  ]
}

不幸的是，none 的建议解决方案对我有用。我怎样才能正确构建它？

编辑：

NPM 版本：5.5.1 节点版本：8.9.0 Vue CLI：v3.0.0-beta.15

创建应用程序的确切命令是 vue create my-app，我选择了 vue-router, vuex, sass, babel, typescript, unit-jest, e2e-nightwatch。

Vue.config.js

const webpack = require('webpack');
const path = require('path');

module.exports = {
  lintOnSave: false,
    baseUrl: '/en-us/credit-application/v2',
    outputDir: '/dist/public',
    configureWebpack: {
        devServer: {
            disableHostCheck: true,
            host: '0.0.0.0',
            publicPath: '/en-us/credit-application/v2',
            openPage: 'en-us/credit-application/v2',
            open: true,
            historyApiFallback: true
        },
        plugins: [
            new webpack.IgnorePlugin(/^\.\/locale$/, /moment$/),
        ]
    }
};

错误：

我在控制台中得到了两个。

Uncaught SyntaxError: Unexpected token < chunk-vendors.61f2fa0f.js:1

Uncaught SyntaxError: Unexpected token < app.acdc6caf.js:1

chunk-vendors.js 导致此文件：

Answer 1

我终于想通了。原来是web服务器配置问题。与 babel 或 vue-cli 模板无关。

在我的 server.js 文件中，我有以下行来提供我的文件：

let staticPath = path.posix.join('/en-us/credit-application/v2', 'public');
app.use(staticPath, express.static(path.join(__dirname + '/public')));
app.get('/*', (req, res) => {
    res.sendFile(path.join(__dirname+'/public/index.html'))
});

第一行导致错误。我将其更改为：

let staticPath = path.posix.join('/en-us/credit-application/v2');

一切正常！非常感谢 ippi 为我指明了正确的方向。
