Rails 5 + Angular 2 应用程序部署到 Heroku - 构建“成功”但部署错误

Question

这是我的第一个 SO 帖子，所以请放轻松。

我正在尝试在 client 文件夹中部署一个嵌入了 Angular 2 的 Rails-API 应用程序，以便我可以一次性部署整个应用程序。但是，当使用git push heroku master 进行部署时，尽管应用无法部署，但构建“成功”。

首先我将我的 Angular 客户端应用程序链接到公用文件夹：

$ rm -rf public
$ ln -s client/dist public

然后我添加了以下构建包：

$ heroku buildpacks:add https://github.com/jasonswett/heroku-buildpack-nodejs
$ heroku buildpacks:add heroku/ruby

这是我的 package.json：

 {
  "name": "my_app",
  "version": "0.0.0",
  "license": "MIT",
  "angular-cli": {},
  "scripts": {
    "lint": "tslint \"src/**/*.ts\"",
    "test": "ng test",
    "pree2e": "webdriver-manager update",
    "e2e": "protractor",
    "preinstall": "npm install -g node-gyp",
    "heroku-postbuild": "ng build"
  },
  "private": true,
  "dependencies": {
    "@angular/common": "2.0.0-rc.5",
    "@angular/compiler": "2.0.0-rc.5",
    "@angular/core": "2.0.0-rc.5",
    "@angular/forms": "0.3.0",
    "@angular/http": "2.0.0-rc.5",
    "@angular/platform-browser": "2.0.0-rc.5",
    "@angular/platform-browser-dynamic": "2.0.0-rc.5",
    "@angular/router": "3.0.0-rc.1",
    "core-js": "^2.4.0",
    "rxjs": "5.0.0-beta.11",
    "ts-helpers": "^1.1.1",
    "zone.js": "0.6.12",
    "@types/jasmine": "^2.2.30",
    "angular-cli": "1.0.0-beta.11-webpack.8",
    "codelyzer": "~0.0.26",
    "jasmine-core": "2.4.1",
    "jasmine-spec-reporter": "2.5.0",
    "karma": "0.13.22",
    "karma-chrome-launcher": "0.2.3",
    "karma-jasmine": "0.3.8",
    "karma-remap-istanbul": "^0.2.1",
    "protractor": "4.0.3",
    "ts-node": "1.2.1",
    "tslint": "3.13.0",
    "typescript": "2.0.0",
    "awesome-typescript-loader": "2.2.1"
  },
  "devDependencies": {
  }
}

按照this问题帖子的建议将"awesome-typescript-loader": "2.2.1"添加到package.json依赖项也没有解决错误。

仅供参考，我一直在关注 Jason Swett 的这个主题指南：How to Deploy a Rails Application with an Angular CLI Webpack Front-End

git push heroku master之后的日志相关部分：

为了调试此问题，是否有任何其他相关信息需要了解？

Answer 1

"scripts": {
"start": "ng serve --proxy-config proxy.conf.json",
"lint": "tslint \"src/**/*.ts\"",
"test": "ng test",
"pree2e": "webdriver-manager update",
"e2e": "protractor",
"heroku-postbuild": "ng build --prod"
},  

添加

"start": "ng serve --proxy-config proxy.conf.json",

在推送到 heroku 之前不要忘记提交您的更改 :)
