Heroku deploy -发生未处理的异常:找不到模块'@angular-devkit/build-angular/package.json‘

Question

我的项目在我的本地机器上运行良好，但在尝试将其实时部署到Heroku时出现以下错误：

我收到错误:出现未处理的异常:找不到模块'@angular-devkit/build-angular/package.json‘

我已经更新了我的Heroku引擎，以匹配我的本地机器：

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

这位于我的dev依赖项中：

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

下面是完整的Heroku日志--结尾错误：

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

只需将"@angular-devkit/build-angular"："^0.901.1“从devDependencies复制到package.json文件的依赖项中！几分钟前也有同样的问题。

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

请务必将您的启动脚本更改为"node“或您的服务器文件的名称，为了进一步的故障排除，这里有一个关于如何将angular应用程序部署到https://medium.com/@ryanchenkie_40935/angular-cli-deployment-host-your-angular-2-app-on-heroku-3f266f13f352的指南
