Unable to start Cypress with ELECTRON_RUN_AS_NODE=1

Current behavior

If you set env with ELECTRON_RUN_AS_NODE=1, with MacOS, you are not able to start the Cypress with

ELECTRON_RUN_AS_NODE=1 npx cypress run

You’ll get error: Error: Cannot find module '/Users/<username>/Library/Caches/Cypress/10.6.0/Cypress.app/Contents/MacOS/Contents/Resources/app/index.js'

Checking the code, it seems that here is where it went wrong: https://github.com/cypress-io/cypress/blob/b615e8ac30b681b4dc8485afe9814ff453da1fbf/cli/lib/exec/spawn.js#L175

The correct path, at least for Mac, should be:

path.join(state.getBinaryPkgPath(path.join(executable, '..', '..', '..')), '..', 'index.js');

Desired behavior

Cypress should start correctly

Test code to reproduce

Try run with

ELECTRON_RUN_AS_NODE=1 npx cypress run

I got the same problem on MacOS. It’s different on Linux:

$ ELECTRON_RUN_AS_NODE=1 yarn cypress run                                                                         main
yarn run v1.22.11

Seems similar to #17412.

Looking at the docs…

Using the ELECTRON_RUN_AS_NODE=1 env var is experimental and not fully tested, so may not work in all environments.

To figure out the priority on fixing this bug - do you have a specific use case in mind where you need to launch with ELECTRON_RUN_AS_NODE?

It says missing dependency, but this might be a red herring.
