Question

我的项目可以在本地计算机上完美运行，但是在尝试将其实时部署到Heroku时出现此错误：

我遇到错误：发生未处理的异常：找不到模块'@ angular-devkit / build-angular / package.json'

我还更新了Heroku引擎以使其与本地计算机相匹配：

"engines": {
  "node": "12.16.2",
  "npm": "6.14.4"
}

这就是我的开发依赖项：

"@angular-devkit/build-angular": "^0.901.1"

以下是完整的Heroku日志--tail错误：

admin-platform@0.0.0 start /app
ng serve
An unhandled exception occurred: Cannot find module '@angular-devkit/build-angular/package.json'
Require stack:

提前谢谢！

只需从devDependencies复制“ @ angular-devkit / build-angular”：“ ^ 0.901.1”到package.json文件中的依赖项即可！几分钟前出现了同样的问题。

"dependencies": {
  "@angular-devkit/build-angular": "^0.901.1",
   ...
}

请确保将启动脚本更改为“ node server.js”或服务器文件的名称，以进行进一步的故障排除，此处提供了有关如何在heroku https://medium.com/@ryanchenkie_40935/angular-cli-deployment-host-your-angular-2-app-on-heroku-3f266f13f352
