NPM is giving me an error using npm install

Question

A friend shared with me a theme he is developing for WordPress, and I cloned his repo in my /themes folder, first thing I tried was to run "npm install" in the theme folder in order to get gulp and other npm cool features.

This is what it returns:

$ npm install
npm ERR! code EINTEGRITY
npm ERR! sha1-fjL3W0e4epHQRhHxvxQQmsAGUdc= integrity checksum failed when using sha1: wanted sha1-fjL3W0e4epHQRhHxvxQQmsAGUdc= but got sha512-kV/CThkXo6xyFEZUugw/+pIOywXcDbFYgSct5cT3gqlbkBE1SJdwy6UQoZvodiWF/ckQLZyDE/Bu1M6gVu5lVw== sha1-fjL3W0E4EpHQRhHxvxQQmsAGUdc=. (36808 bytes)

npm ERR! A complete log of this run can be found in:
npm ERR!     C:\Users\rinor\AppData\Roaming\npm-cache\_logs\2020-04-04T17_30_54_859Z-debug.log

After trying installing it globally it gave me back the same error so I came up with uninstalling node.js from my pc and then download and install the LTS version (12.16.1). Rebooted, tested and it seemed to work as I tried typing "node -v" && "npm -v". But when I return to my theme and go for "npm install" it gives me the same error.

Here is my package.json content

    "webpack": "^4.29.0",
    "webpack-cli": "^3.2.1"
  },

}

These are the erros that the debug shows

Have you read the log file? What does it says besides this error? — Nino Filiu, Apr 04 '20 at 18:14
Does this answer your question? [When I run \`npm install\`, it returns with \`ERR! code EINTEGRITY\` (npm 5.3.0)](https://stackoverflow.com/questions/47545940/when-i-run-npm-install-it-returns-with-err-code-eintegrity-npm-5-3-0) — razki, Apr 05 '20 at 19:42
Nope, i tried the solutions proposed there and none of that did work — Rino Crispino, Apr 06 '20 at 10:12

You don't mention whether you had package-lock.json or not. In some cases the following might help. But first make sure you understand what's going on. npm tells you that the checksum from https://registry.npm.org doesn't match the one from package-lock.json. Either it changed in the registry, or...

Solution Consider the line from the output:

npm ERR!
  sha1-fjL3W0e4epHQRhHxvxQQmsAGUdc=
integrity checksum failed when using sha1: wanted
  sha1-fjL3W0e4epHQRhHxvxQQmsAGUdc=
but got
  sha512-kV/CThkXo6xyFEZUugw/+pIOywXcDbFYgSct5cT3gqlbkBE1SJdwy6UQoZvodiWF/ckQLZyDE/Bu1M6gVu5lVw== sha1-fjL3W0E4EpHQRhHxvxQQmsAGUdc=
. (36808 bytes)

Find the package in package-lock.json by the first two integrity checksums (sha1-...), and put the third one (sha512-...) into its "integrity" field.
