[yarn][beta] "engine node is incompatible" error

See original GitHub issue

When I install the beta version (3.0.0-beta.9) of node-fetch with Yarn, Yarn returns an error:

error fetch-blob@1.0.7: The engine "node" is incompatible with this module. Expected version "^10.17.0". Got "14.15.4"
error Found incompatible module.

So I have to force the installation with --ignore-engines.

Reproduction

Steps to reproduce the behavior:

Install Node.js version 14 (I use v14.15.4)
Install Yarn (sudo npm i -g yarn)
Create an empty folder, open it in a terminal
Install node-fetch version 3 beta with Yarn (yarn add --dev node-fetch@^3.0.0-beta.9)

Expected behavior

No error because v14 is the current stable version of Node.js.

Your Environment

software	version
node-fetch	3.0.0-beta.9
node	14.15.4
yarn	1.22.5
Operating System	macOS 11.4

Just updated - can confirm.

The reason for the issue is because of the caret. It usually declares that the most recent minor version be used but because the development versions don’t use semver, npm doesn’t understand which version to fetch. Instead, use yarn add node-fetch@next or yarn add node-fetch@3.0.0-beta.9

unfortunately "node-fetch": "^3.0.0-beta.10" would still fetch the wrong version. Sticking to fixed version for now.
