Configuration ‘prod’ could not be found

Probem:

I am trying to serve the app via configuration for prod in Angular 6 using below command.

ng serve --configuration=prod

But it gives me below error :

Configuration 'prod' could not be found in project 'platform-ui'.

Error: Configuration 'prod' could not be found in project 'platform-ui'.

Solution :

If you look at your angular.json file, you’ll see that you have finer control over settings for each configuration.

Now look for serve tag in json

“serve”: {
“builder”: “@angular-devkit/build-angular:dev-server”,
“options”: {
“browserTarget”: “platform-ui:build”
},


and add configuration for your custom server like this :


“configurations”: {
“production”: {
“browserTarget”: “platform-ui:build:production”
},
“qa”: {
“browserTarget”: “platform-ui:build:qa”
},

now try to run below command again

ng serve --configuration=prod
