I have an angular project and I want to use ionic for mobile. I did ionic init. When I run the command ionic serve, I get this error: > ng.cmd run app:serve --host=localhost --port=8100 [ng] Error: Unknown arguments: host, port [ERROR] ng has unexpectedly closed (exit code 1).

Here is my package.json : { "scripts": { "ng": "ng", "start": "ng serve", "build": "ng build", "buildrod": "ng build --configuration production", "watch": "ng build --watch --configuration development", "test": "ng test" }, "private": true, "dependencies": { "@angular/animations": "^14.2.4", "@angular/cdk": "^14.2.3", "@angular/common": "^14.2.4", "@angular/compiler": "^14.2.4", "@angular/core": "^14.2.4", "@angular/forms": "^14.2.4", "@angular/material": "^14.2.3", "@angular/platform-browser": "^14.2.4", "@angular/platform-browser-dynamic": "^14.2.4", "@angular/router": "^14.2.4", "angular-material-dynamic-themes-eli": "^1.0.4", "bootstrap": "^5.1.3", "flag-icons": "^6.4.4", "material-design-icons": "^3.0.1", "ngx-editor": "^15.0.0", "rxjs": "^7.4.0", "zone.js": "~0.11.4" }, "devDependencies": { "@angular-devkit/build-angular": "^14.2.4", "@angular/cli": "^14.2.4", "@angular/compiler-cli": "^14.2.4", "@types/jasmine": "^4.3.0", "@types/node": "^18.7.23", "jasmine-core": "^4.4.0", "karma": "^6.4.1", "karma-chrome-launcher": "~3.1.0", "karma-coverage": "~2.0.3", "karma-jasmine": "~4.0.0", "karma-jasmine-html-reporter": "~1.7.0", "tslib": "^2.3.1", "typescript": "~4.8.4" } } How can I fix the host/port missing arguments ? After a comment of SimpleDev, I tried all answer here : Use npm install @ionic/app-scripts@latest --save-dev : The @ionic/app-scripts package is deprecated and not updated to angular 14 or 15. When running it, I get Undefined variable standalone_static_library in binding.gyp while trying to load binding.gyp.
