[BUG] scripts-prepend-node-path not respected in npm v8.1.2

[sajal50]

Is there an existing issue for this?

• I have searched the existing issues

This issue exists in the latest npm version

• I am using the latest npm

Current Behavior

I have a postinstall script in my package.json which does which node.

{
  "name": "test",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1",
    "postinstall": "which node"
  },
  "keywords": [],
  "author": "",
  "license": "ISC"
}

With node v16.13.1 and npm v8.1.2, I get the following result -

sajal@C02WM2ARHTDD test % ../node-v16.13.1-darwin-x64/bin/node ../node-v16.13.1-darwin-x64/bin/npm install --scripts-prepend-node-path=true

> [email protected] postinstall
> which node

/usr/local/bin/node

node is resolving to my global installation.

Expected Behavior

However, with node v14.8.2 and npm v6.14.15, node resolves to my local installation -

sajal@C02WM2ARHTDD test % ../node-v14.18.2-darwin-x64/bin/node ../node-v14.18.2-darwin-x64/bin/npm install --scripts-prepend-node-path=true

> which node

IIUC, with scripts-prepend-node-path=true, should continue to resolve to my local installation even with node v16.13.1 and npm v8.1.2. If this has been deprecated, please let me know.

Steps To Reproduce

As explained in Current Behavior section.

Environment

• OS: macOS 10.15.7
