我有一个Angular 5 App。
这就是我在 package.json

我在其中创建了一个 server.js 。
constexpress=require('express');
constapp=expres();
constpath=require('path');
app.us(express.static(__dirname+'/dist'));
app.listen(process.env.PORT||8080);
//PathLocationStradegy
app.get('/'function(req,res) {
res.sendFile(path.join(__dirname+'/dist/index.html'));
});
console.log('Console Listening');
然后,我运行这些命令
heroku auth:login
Email : johndoe@outlook.com
Password : #########
heroku create iproject-demo
heroku git:remote iproject-demo
git status
git add -A
git push heroku master
我尝试过运行

但是当我去APP时:

我看到了这个
如何继续进行调试?
我现在对任何建议持开放态度。
任何提示/建议/帮助都将非常感谢!

以下是我如何使用Angular应用程序部署和使用Heroku:
server.js
应该如下所示:https://hastebin.com/zavehahide.js package.json
中,将@angular/cli
和@angular/compiler-cli
从devDependencies
移至dependencies
package.json
中,将postinstall: ng build --prod
和start: node server.js
添加到scripts
你应该好好去。

通常当我发生此错误时,我遇到节点依赖性问题。尝试删除node_modules文件夹和dist文件夹。从那里再次旋转一切,这模仿了heroku将如何建立你的项目。
答案 2 :(得分:2)
我建议更简单,如果你想在heroku上部署后端作为api和github上的前端并激活浏览计算机上的跨源资源共享,我实际上正在构建这样的应用程序,这是我的计划,否则如果你得到这方面的任何好消息你都在更新我

在server.js
中,您需要将您的http调用重定向到索引。
app.route('/*', function(req,res) {
res.redirect(__dirname + '/dist/index.html')
})
在上面,它会将任何调用重定向到index.html。

更正Server.js中的代码
const express = require('express');
const app = express();
const path = require('path');
app.use(express.static(__dirname+'/dist'));
app.listen(process.env.PORT||8080);
//Path Location Strategy
app.get('/', function(req, res) {
res.sendFile(path.join(__dirname+'/dist/index.html'));
});
console.log('Console Listening');

在点击网址之前尝试运行logs
命令。
$ heroku logs
然后查看日志以获取更多详细信息。
答案 5 :(得分:1)
如果你要在heroku上建立产品,你将面临内存超出问题。所以自由类型不起作用。
因此,尝试在本地构建并使用express提供dist文件。
在PROC文件中使用相同的命令
Heroku local或Heroku本地网站:验证您在本地的更改
答案 6 :(得分:1)
在回答如何进一步调试。运行您的应用程序,然后立即登录Heroku,转到您的应用程序,然后在“更多”下拉菜单中,单击“查看日志”。应该帮助你!
我相信有一种方法可以通过终端查看实时日志,这样您就可以确切地看到失败的原因。
答案 7 :(得分:1)
尝试在package.json文件中添加@angular-devkit/build-optimizer
作为包。
"dependencies": {
"@angular-devkit/build-optimizer": "^0.4.0",
...
}
这允许安装后标志--aot
运行。出于某种原因,这个包不再构建了。
