Question

我正在将Angular-universal与nest-js一起使用，它在本地运行良好，但是当我在Heroku上部署它时，出现此错误：

Error: Cannot find module './drivers/node-mongodb-native/connection'.

我不知道是什么原因造成的。这是我的package.json：

Answer 2

我临时固定在路径\ node_modules @ nestjs \ ng-universal \ dist \ webpack-config.factory.js中，将mongoose | mongodb添加到

 whitelist: /^(?!(@nestjs\/(common|core|microservices)|livereload|concurrently)).*/

以这种方式

 whitelist: /^(?!(@nestjs\/(common|core|microservices)|livereload|concurrently|mongoose|mongodb)).*/
