我昨天在 vue/cli github 错误页面上发布了我的环境详细信息。看起来所有错误都没有得到响应，所以我希望你们能帮助我。

短版： 我有一个 Vue/Firebase 项目。我正在尝试构建它，以便可以在 Firebase 上部署它。当我通过 Vue UI 提供该项目时，该项目运行良好。当我运行npm run build时，创建的 /dist/index.html 文件的 href 都以“/undefined/...”开头。显然，当我将它部署到 Firebase 时，这不起作用，给我这样的错误Uncaught SyntaxError: Unexpected token '<'

可疑的事情：

  1. 部署到 Firebase 后，它仍然能够找到我的 favicon.ico，即使它认为它位于https://myproject.firebaseapp.com/undefined/favicon.ico.
  2. 在我的环境信息中，我有npmGlobalPackages: @vue/cli: Not Found. 我尝试的步骤在上述 GitHub 页面的评论中，但我无法更改。
  3. 在我的环境信息中，它说Browsers: Edge: 44.18362.449.0. 我不知道这是否重要，但我只是在 Chrome 中工作和测试。

我尝试过的事情

  1. 根据许多 stackoverflow 的答案，我可以Try by adding <base href="/" /> into the <head> of your index.html. Hope it will work., 和You might have used "./" prefix for Relative path in src attributes of your index.html, Just replace it with "<%= BASE_URL %>" and it will work fine.. 我都试过了，还是不行（我也试过提问者的npm install再次跑步的建议）。除了我所说的更改之外，我还有生成的 firebase index.html 文件。

  2. 根据许多其他问题，这Unexpected token '<'可能是 Firebase 的缓存问题。他们说我可以尝试硬刷新（我尝试过）或清除缓存（我也尝试过）。我什至尝试使用完全不同的计算机，但仍然遇到相同的错误。老实说，我不认为是这样，因为我不认为我的 dist/index.html 文件应该在其中未定义，这是在我将其上传到 Firebase 之前。

代码： vue.config.js

module.exports = {
  "transpileDependencies": [
    "vuetify"
  ],
  devServer: {
        proxy: 'https://myredactedprojectname.com/',
    },
  publicPath: process.env.NODE_ENV === 'production'
    ? '/' + process.env.CI_PROJECT_NAME + '/'
    : '/'
}

所以，事实证明我的环境变量没有设置，这就是它出现未定义的原因。我只是将我的公共路径设置为“/”。

vue.config.js：

module.exports = {
  "transpileDependencies": [
    "vuetify"
  ],
  devServer: {
        proxy: 'https://myprojectname.com/',
    },
  publicPath: '/'
}
