You may have a package cached and it's failing the checksum comparison, you can try:
$ cd <project_directory>
$ rm -rf package-lock.json npm-shrinkwrap.json node_modules
$ npm cache clean --force
$ npm cache verify
$ npm install
or look here: When I run `npm install`, it returns with `ERR! code EINTEGRITY` (npm 5.3.0)
Since you're building something with Crypto I'd be extra cautious and ensure that this is in fact just an error/false positive and not a malicious package failing the checksum. Very low chance of the latter, but I'd pay a little extra attention at this step.

Figured it out. Looks like I had an issue with my Package-lock.json file within my project. Not sure what in particular caused the issue but deleting that folder and re-running npm install fixed my issue.

At first you need to initialize you npm package for package.json file.
using that command npm init -yes . Create a default package.json file.
Then need to install it globally using this command :
npm install parcel-bundler -g
Also you can try to save it in your package.json file.
npm install parcel-bundler -g --save-dev

Are you using ng new? What is your ng --version, are you sure you are up-to-date with Angular CLI as well? (Also, you should use at least Node LTS version (12.18 at the moment), check with node -v).
Also, try cleaning your cache:
npm cache clean --force
then try the command again.
