我正在将Vue.js与vue-cli一起使用，并尝试使捆绑了webpack的应用程序在Google Cloud应用程序引擎上运行，以便我和后端开发人员可以更轻松地在集成上一起工作。我们俩都没有使用过Google Cloud的经验，并且发现使用它非常困难。
将项目（当前没有关联的后端）上传到App Engine之后，我的index.html页面将加载，但是Vue.js未加载，因此显然不会路由任何内容。我尝试了多种方法，包括更改.yaml文件（不变），手动调用index.js和main.js文件（无法识别Vue），并确保我所有的devDependencies也都是常规依赖项。
然后，我遵循了一个围绕React构建的教程，该教程使用Google Cloud SDK从我的终端部署我的应用程序。将所有devDependencies复制到我package.json中的依赖项后，它已成功部署...但是当我在浏览器中打开页面时，它出现502 Bad Gateway错误，并带有附加文本“ nginx”。
来自我的package.json（同样，这是来自vue-cli模板，我自己没有配置它）：

在我的app.yaml中（真正的后端将在php中，但这是在部署时生成的内容）：
env: flex
runtime: nodejs
有关该问题可能是什么的任何线索？我知道502错误表示服务器端出了点问题，但是我唯一的猜测是缺少后端环境正在破坏前端。
编辑：日志显示两个错误，每个错误都针对每个.vue组件文件重复。
