所有帮助将不胜感激。如果我忽略了提供调试此部署所需的任何内容,请告诉我。感谢您的时间。
Heroku 要求您的应用程序有后端。为了实现这一目标,我们将向您的应用程序添加node和express。我可以看到大多数更改已经存在于您的中package.json,但仍然请执行以下步骤,并请确保遵循下面提到的所有步骤:
在你的 package.json 中,复制
"@angular/cli": "1.7.3"", "@angular/compiler-cli": "^5.2.0"
Run Code Online (Sandbox Code Playgroud)
从devDependencies到dependencies。
在 package.json 中创建安装后脚本-
在 下"scripts",添加安装后命令:
"postinstall": "ng build --aot --prod"
Run Code Online (Sandbox Code Playgroud)
这告诉 Heroku 使用提前 (AOT) 编译器构建应用程序并使其可用于生产。这将创建一个dist文件夹,我们的应用程序的所有 html 和 javascript 转换版本都将从中启动。
添加node和npm引擎-
您将需要添加 Heroku 将用来运行您的应用程序的 Node 和 NPM 引擎。最好它应该与您机器上的版本相同。因此,运行node -v并npm -v获取正确的版本并将其包含在您的package.json文件中,如下所示:
"engine": { "node": "8.9.4", "npm": "5.6.0" }

复制typescript到dependencies-
复制"typescript": "~2.5.3"从devDependencies到dependencies也告知 Heroku 使用什么 typescript 版本。
安装增强解析3.3.0:
运行命令:
npm install enhanced-resolve@3.3.0 --save-dev

安装服务器来运行您的应用程序:
在本地,我们从终端运行ng serve以在本地浏览器上运行我们的应用程序。但我们需要设置一个 Express 服务器来运行我们的生产就绪应用程序(从dist创建的文件夹中),以确保轻量级和快速加载。通过运行以下命令安装 Express 服务器:
npm install express path --save

在应用程序的根目录中创建一个 server.js 文件并粘贴以下代码:
//Install express server
const express = require('express');
const path = require('path');
const app = express();
// Serve only the static files form the dist directory
app.use(express.static(__dirname + '/dist'));
app.get('/*', function(req,res) {
res.sendFile(path.join(__dirname+'/dist/index.html'));
});
// Start the app by listening on the default Heroku port
app.listen(process.env.PORT || 8080);

现在运行:
git push heroku your_remote_name

Heroku 将查看您的package.json软件包并安装它们。它将运行postinstall,然后node server.js启动您的应用程序。您可以检查“活动”选项卡并打开“构建日志”以查看其实际运行情况。希望能帮助到你!
