Getting : npm WARN using --force Recommended protections disabled

I have an old Nuxt.js package that was developed in Node 12 and I want to use it now with Node 16 (the latest stable) but when I try to install my packages by npm install I'm getting the versions difference errors.

But I know the packages are up to date. So, I'm trying to force clear my npm cache by sudo npm cache clean -f but I'm getting this error:

npm WARN using --force Recommended protections disabled.

The environment is ubuntu 20.04 and this is my package.json file:

{
  "name": "frontend",
  "version": "1.0.0",
  "private": true,
  "scripts": {
    "dev": "nuxt",
    "build": "nuxt build",
    "start": "nuxt start",
    "generate": "nuxt generate"
  },
  "dependencies": {
    "@nuxtjs/auth": "^4.9.1",
    "@nuxtjs/axios": "^5.13.6",
    "@nuxtjs/dotenv": "^1.4.1",
    "@nuxtjs/google-adsense": "^1.4.0",
    "@nuxtjs/gtm": "^2.4.0",
    "@nuxtjs/router": "^1.6.1",
    "better-vue-input-tag": "^1.1.0",
    "bootstrap": "^5.1.3",
    "bootstrap-vue": "^2.21.2",
    "core-js": "^3.19.2",
    "eslint": "^8.3.0",
    "jquery": "^3.6.0",
    "laravel-vue-pagination": "^2.3.1",
    "node-sass": "^6.0.1",
    "nuxt": "^2.15.8",
    "popper.js": "^1.16.1",
    "sass-loader": "^12.3.0",
    "vform": "^2.1.2",
    "vue-autosuggest": "^2.2.0",
    "vue-gtag": "^1.16.1",
    "vue-infinite-loading": "^2.4.5",
    "vue2-google-maps-withscopedautocomp": "^0.12.1"
  },
  "devDependencies": {
    "eslint-config-prettier": "^8.3.0",
    "eslint-plugin-prettier": "^4.0.0",
    "ip": "^1.1.5",
    "prettier": "^2.5.0"
  }
}

How can I use the force flag without getting errors?
