Angular dependencies not found

Question

I am having problems creating angular projects. Until a few moments ago it was working fine, but now when I create a new project( ng new <project_name> ) the node_modules folder that contains all installed dependencies doesn't appear anymore.

I can't even run( ng serve ) the project because of this. It just prints on the screen:

Node packages may not be installed. Try installing with 'npm install'.
Error: Could not find the '@angular-devkit/build-angular:dev-server' builder's node package.

I tried all these commands:

npm uninstall --save-dev @angular/cli
npm uninstall --save @angular/cli
npm cache clean --force
npm install --save @angular/cli
npm install

Especially npm install that only prints up to date in 662ms. Also in other projects that have the folder, when I try to install other dependencies it only shows as in the example:

changed 36 packages in 14s
2 packages are looking for funding

I search the project and find nothing. I don't know what else to do. If someone can please help me solve this I would really appreciate it.

EDIT ---------- SOLUTION

I finally managed to solve it with the option of an older version of npm, which in my case was npm install -g npm@7, and then I was able to use the npm install command. The node_modules folder with all the dependencies is working fine now. The only thing you have to watch out for later is the dependency conflicts.

Try deleting node_modules folder and then just run npm install in the project root (without mentioning any dependency name) — AdityaParab

The error is saying it cannot find "@angular-devkit/build-angular:dev-server". so you should install it using the following command. The command will fail if you do not have peerDependencies set to true so I will add the force flag.

npm install @angular-devkit/build-angular --force
