unable to resolve dependency tree error for creating new angular project

Open the folder you create with ng new and open the package.json file. In devDependencies change the version of “jasmine-core” 3.6.0 to 3.8.0 and “karma-jasmine-html-reporter” from 1.7.0 to 1.6.0 and save it. Then go back to Terminal and go to your project and run npm install. Now it works and you can run ng serve.

Edit 2021

"jasmine-core": "~3.8.0",
"karma-jasmine-html-reporter": "^1.7.0"
