Hello every one,
I am developing an ionic application. At first my angular cli version is 9.0. When i run the command line"ionic cordova build android"，it works.But now the angular cli update to 14.0.1.I try to run the command line"ionic cordova build android" then get error like "An error occurred while running subprocess ng."
The following is detailed error description:
"
ionic cordova build android
> ng.cmd run app:ionic-cordova-build --platform=android
Error: Unknown argument: platform
[ERROR] An error occurred while running subprocess ng.

ng.cmd run app:ionic-cordova-build --platform=android exited with exit code 1.

Re-running this command with the --verbose flag may provide more information.

Solution 1

Error: Unknown argument: platform

You are (presumably) using incorrect options. Check the angular documentation to see what it should be.

Could you please tell me more about the incorrect options. No options are provided during command operation.

Look at the messages produced:

> ng.cmd run app:ionic-cordova-build --platform=android
Error: Unknown argument: platform
[ERROR] An error occurred while running subprocess ng.
ng.cmd run app:ionic-cordova-build --platform=android exited with exit code 1.

It clearly shows ng.cmd is being called with the --platform=android option. As I said above, you need to check the angular documentation. This is not a programming problem that we can help with, it is purely something to do with the product(s) you are using.

Solution 3

If you run this command: ng add @ionic/cordova-builders it should add the required builders that are missing from the angular.json file generated by the Ionic CLI.
