Question

我正在尝试将Angular应用程序部署到Heroku。我这样做的经验有限，并且遇到错误。我对stackoverflow的搜索使我尝试了不同的配置，但是每次遇到错误时，我都会尝试。我得到的最接近的是脚本中没有包含“ postinstall”的情况，这种情况下构建成功，但是我仍然收到相同的代码H10应用程序错误。

我已经尝试过“ postinstall：ng build --aot --prod”，“ heroku-postbuild”：“ ng build --aot --prod”和ng build --aot --prod”，但是没有差异，由于此行，每次构建都会失败。

这是我的package.json

  }
}

我的server.js

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/hockey-app'));

app.get('*', function(req,res) { 
    res.sendFile(path.join(__dirname, '/dist/hockey-app/index.html'));
});

// Start the app by listening on the default Heroku port
app.listen(process.env.PORT || 8080);

感谢您的帮助。谢谢。

编辑：构建成功并部署，但继续出现Application错误。 Heroku日志：

Answer 1

使用heroku-postbuild，它将代替普通的构建脚本。如果使用postinstall，它将两次构建应用程序（npm run postinstall && npm run build）。将代码推送到heroku时，您应该能够看到它。

当您的应用程序成功构建后，heroku将使用启动脚本来启动您的应用程序。我认为您的开始脚本无法在heroku上运行，因为它同时是一个npm模块，我在package.json中看不到，而“ ng build --watch”则用于本地开发，而不是用于在上面运行代码heroku。

我建议为您的项目文件夹创建一个Procfile。
https://devcenter.heroku.com/articles/getting-started-with-nodejs#define-a-procfile
Heroku将使用此命令来启动应用程序服务器。
Procfile：

web: node server.js

尝试移动

"@angular/cli": "~6.2.5",
"@angular/compiler-cli": "^6.1.0"

从devDependencies到dependencies ...
