Cypress pre-installs not working as expected with NPM 7+ / Node 15+

[flotwig]

Current behavior

We use npm_config_argv to generate the pre-release binary URL when the binary is installed via CLI arg, like with "npm install .....cypress.tgz" or "npx ......cypress.tgz open":

cypress/cli/lib/tasks/install.js

Lines 86 to 106 in 64b1aef

	// convert a prerelease NPM package .tgz URL to the corresponding binary .zip URL
	const getBinaryUrlFromPrereleaseNpmUrl = (npmUrl) => {
	let parsed
	try {
	parsed = url.parse(npmUrl)
	} catch (e) {
	return
	}
	const matches = betaNpmUrlRe.exec(parsed.pathname)
	if (parsed.hostname !== 'cdn.cypress.io' || !matches) {
	return
	}
	const { version, artifactSlug } = matches.groups
	parsed.pathname = `/beta/binary/${version}/${os.platform()}-${os.arch()}/${artifactSlug}/cypress.zip`
	return parsed.format()

However, npm_config_argv was removed in NPM 7: https://stackoverflow.com/a/68111110/3474615 npm/cli#1995

So this is broken for those users.

Pre-releases still work with NPM 7 if you put the cypress.tgz URL in package.json, and then run npm install.

Desired behavior

We have to hard-code the binary URL in the CLI NPM package, since npm_command does not provide the required metadata to cover this use case.

The only other way I can think would be some kind of climb up the process tree to try and read argv from parent processes, but that sounds hard to maintain.

Looks like the correct env var to use is npm_package_resolved:
