Error when installing cypress using Node.js version < 8.12.0

[jennifer-shehane]

Current behavior:

When installing Cypress with Node.js version less than 8.12.0 install is prevented by the following errors.

yarn

Warning you are not on compatible engine

error execa@3.3.0: The engine "node" is incompatible with this module. Expected version "^8.12.0 || >=9.7.0". Got "8.0.0"
error Found incompatible module.

npm install

Even more cryptic - there's just an execa error

 npm i --save-dev cypress

> cypress@4.0.2 postinstall /Users/jennifer/Dev/cypress-transform-test/node_modules/cypress
> node index.js --exec install

/Users/jennifer/Dev/cypress-transform-test/node_modules/execa/index.js:18

Desired behavior:

Cypress install should support Node.js 8+ as of 4.0.0, so should support an install with Node.js versions as low as 8.0.0

Why

Execa introduced this breaking change (a fix for a change that should have gone in their 2.0.0 release I guess) without actually noting it as a breaking change., requiring at least Node.js 8.12.0 in their 2.0.1 release.

Execa 2.0.1 release notes: https://github.com/sindresorhus/execa/releases/tag/v2.0.1

You can see this change by diffing the package.json from the releases

• execa 2.0.0 package.json sindresorhus/execa@ec10a4c#diff-b9cfc7f2cdf78a7f4b91a753d10865a2
• execa 2.0.1 package.json sindresorhus/execa@97ef87d#diff-b9cfc7f2cdf78a7f4b91a753d10865a2

Code required

We should revert execa dep in the cli back down to 2.0.0.

Versions

Cypress 4.0.0

The code for this is done in cypress-io/cypress#6513, but has yet to be released.
We'll update this issue and reference the changelog when it's released.

I actually don't think this is closed. We really need to go back to execa 1.0.0, because 2.0.1 was simply changing the engines field and the real effective non-support for 8.0.0 went into 2.0.0.

This wasn't caught though because I don't think our node-version tests are running properly: #6559

[jennifer-shehane]

I verified this by installing the binary from develop myself on Node 8.0.0 - it fails.

FYI the same here, caught 2 weeks ago after trying to switch to the new version - 4.0.0

#!/bin/bash -eo pipefail
$ meteor yarn
yarn install v1.22.0
