Question

在我的angular2项目中，我使用了编译器服务来制作一个动态模块，并在应用程序中在运行时进行渲染。问题是，当我运行ng build --prod命令时，它完成了整个过程，没有任何错误，但是将其托管到herokuapp之后。如果我运行我的应用程序，它将给我类似的错误，

core.js.pre-build-optimizer.js:15714

错误错误：未捕获（承诺）：错误：未加载运行时编译器错误：未加载运行时编译器

如何解决此错误？

Answer 1

Heroku uses postinstall and preinstall hooks，可用于构建：

"preinstall": "npm install -g http-server",
"postinstall": "ng build --prod"

您还可以使用“开始”钩服务：

"start": "http-server dist/"

如果有人需要部署到heroku，请先阅读此文章： https://m.alphasights.com/using-nginx-on-heroku-to-serve-single-page-apps-and-avoid-cors-5d013b171a45#.drmqhuard

使用此构建包：https://github.com/heroku/heroku-buildpack-static

还有这个static.json：

{
  "root": "dist/",
  "routes": {
    "/**": "index.html"
  }
}
