Sometimes cleaning the cache helps: Update Angular after clearing Cache


It looks like it is a cache error. Reinstalling Angular CLI after clearing the npm cache. The below solution work for me, run below 3 commands one by one
npm install chokidar
npm cache clean --force
npm install -g #angular/cli#latest

"npm outdated" and "npm outdated -g" don't show anything so why am I getting these warnings of deprecations?

I have node.js version 12.16.3 (macOS x64), the most current LTS version. The npm version is 6.14.4, which comes as default with the node.js version already stated. My operating system is Catalina 10.15.4 (the latest version).
When I run npm outdated and npm outdated -g nothing is returned, I simply get a new line.
Yet when I run this inside of my project:
npm init followed by npm i --save-dev babel-cli babel-preset-env, I get these warnings:
npm WARN deprecated chokidar#1.7.0: Chokidar 2 will break on node v14+. Upgrade to chokidar 3 with 15x less dependencies.
npm WARN deprecated core-js#2.6.11: core-js#<3 is no longer maintained and not recommended for usage due to the number of issues. Please, upgrade your dependencies to the actual version of core-js#3.
npm WARN deprecated fsevents#1.2.12: fsevents 1 will break on node v14+ and could be using insecure binaries. Upgrade to fsevents 2.
npm WARN deprecated urix#0.1.0: Please see https://github.com/lydell/urix#deprecated
npm WARN deprecated resolve-url#0.2.1: https://github.com/lydell/resolve-url#deprecated
I have tried running npm install chokidar#^3 and I get the exact same warnings.
I have tried running npm install chokidar#latest and I get the exact same warnings.
I can't seem to update what I am being told to update. How can I resolve this issue?
Any help is much appreciated.

This happened due to you cache got corrupted. You need to clean your cache and re-install #angular/cli.
Open command prompt and run below commands.
npm cache clean --force
npm install -g #angular/cli
