If you see the error path then it is pointing to the node modules. This seems like an issue of the node_modules only. You need to delete the node_modules folder and install it again.

My issue get resolved by adding stable version of ng2-material-dropdown into my package.json as below :

After adding this try again npm install and it's working fine.

Getting same error for ng-recaptcha I fixed same problem by adding to tsconfig.json

"compilerOptions": {
        ...
        "paths": { "@angular/*": ["./node_modules/@angular/*"] }
}

Could be that there's an issue in your node_modules folder. Try running npm ci

Solution 5:[5]

Running ng update to move to Angular 11 might also fix this.

Solution 6:[6]

Check for the version compatibility. Your some modules are not compatible with angular version. You have to read the docs of modules before installing it and install the version which is accepted by angular.
