Unable to load schema problem in angular.json file

Question

I have a problem in angular.json file.

{
    "resource": "/e:/P dev/project/Resume_generator/front/angular.json",
    "owner": "_generated_diagnostic_collection_name_#1",
    "code": "768",
    "severity": 4,
    "message": "Unable to load schema from 'e:\\P dev\\project\\Resume_generator\\front\\node_modules\\@angular\\cli\\lib\\config\\schema.json': ENOENT: no such file or directory, open 'e:\\P dev\\project\\Resume_generator\\front\\node_modules\\@angular\\cli\\lib\\config\\schema.json'.",
    "startLineNumber": 2,
    "startColumn": 14,
    "endLineNumber": 2,
    "endColumn": 66
}

After that I tried npm cache clean and again I got an error

npm ERR! As of npm@5, the npm cache self-heals from corruption issues and data extracted from the cache is guaranteed to be valid. If you want to make sure everything is consistent, use 'npm cache verify' instead. On the other hand, if you're debugging an issue with the installer, you can use `npm install --cache /tmp/empty-cache` to use a temporary cache instead of nuking the actual one.

First, run this,

npm cache clean --force

If this is not working, you can delete the node modules file and package-lock.json file

Then run,

npm i
