Incompatibility issue with latest pnpm version 8.0.0

[Demir-Utku]

Expected behavior

Expecting to work this library with the latest pnpm version, which is 8.0.0.

Current behavior

When I want to install chart.js@4.2.1 with pnpm@8.0.0, I got the following error:

ERR_PNPM_UNSUPPORTED_ENGINE  Unsupported environment (bad pnpm and/or Node.js version)

Your pnpm version is incompatible with "/chart.js/4.2.1".

Expected version: ^7.0.0
Got: 8.0.0

This is happening because the package's manifest has an engines.pnpm field specified.

Reproducible sample

https://www.chartjs.org/dist/master/chart.umd.js

Optional extra steps/info to reproduce

You should first install pnpm. Then, to upgrade to the latest version of it, enter this command:

pnpm add -g pnpm

This command will upgrade your pnpm version to the latest. After trying to install chart.js with pnpm, you'll get the error.

Possible solution

Changing one/both of the below fields in package.json will probably resolve the issue:

"engines": {
  "pnpm": "^7.0.0" // Change this to ">=7" to use versions that are greater than 7.
},
"packageManager": "pnpm@7.9.0", // Also this one.
