Angular 11: Error running ng serve command. How to decide?

Question

Angular

Angular version 11, an error pops up when running the command ng serve

"An unhandled exception occurred: ENOENT: no such file or directory, lstat '/home/v4l1k/Work/Practice/node_modules' "

I have already tried updating dependencies and removing node_modules and reinstalling, and clear cache, nothing helps.

package.json

I solved the problem, it turns out the wrong path was in styles in Package.json
Was

"styles": [
              "../node_modules/bootstrap/dist/css/bootstrap.min.css","src/styles.css"
            ],

It became

"styles": [
              "node_modules/bootstrap/dist/css/bootstrap.min.css","src/styles.css"
            ],
