Angular : ng serve works but ng serve --open does not

Question

I have recently started with Angular and I am new to it. I have installed nodejs and typescript as well. When i go to my project directory using the command prompt, the ng serve commands works and compiles the project and i need to open the browser manually. However, when i try it with the --open parameter, i am getting an error in the events.js file as:

throw er; // Unhandled 'error' event

ERROR: spawn cmd ENOENT

My versions are:

Angular CLI: 10.0.4 Node: 12.18.3 npm: 6.14.6 OS: win32 x64 tsc: 3.9.7

Answer 1

It seems to be some library inconsistency. Try:

1. delete node_modules and package-lock.json
2. run npm update
3. run npm install
