MikeMcC399 · 2025-06-06T08:30:58Z

Closes 404 error attempting pre-release binary install on Windows ARM #31831

Additional details

Attempting to install the Cypress binary from the pre-release npm package

https://cdn.cypress.io/beta/npm/14.5.0/win32-x64/develop-ec252f8601d9cec4543085667c7e03ecdab8e82f/cypress.tgz

on the GitHub runner

fails with

cypress:cli URL: https://cdn.cypress.io/beta/binary/14.5.0/win32-arm64/develop-ec252f8601d9cec4543085667c7e03ecdab8e82f/cypress.zip
    Error: Failed downloading the Cypress binary.
Response code: 404
Response message: Not Found

Cypress does not build for win32-arm64 and so there is no such binary available.

PR feat: install win32-x64 binary on win32-arm64 platform #31784 already resolved this issue for regular releases.

This PR changes the URL selection for pre-releases of Cypress running on win32-arm64 to download the corresponding win32-x64 Cypress binary instead.

Steps to test

After this PR is merged, install the generated pre-release package into:

https://github.com/MikeMcC399/cypress-example-kitchensink/tree/use/windows-11-arm-beta

Review the results of workflow:

https://github.com/MikeMcC399/cypress-example-kitchensink/actions/workflows/chrome.yml

How has the user experience changed?

Users will be able to follow the Cypress documentation instructions Install pre-release version successfully also on Windows Arm-based PCs.

@MikeMcC399 Yah, we're aware that it's not that testable ahead of time, but figure the worst that can happen is that it still doesn't work. :/

@jennifer-shehane

Yah, we're aware that it's not that testable ahead of time, but figure the worst that can happen is that it still doesn't work. :/

Thanks for your optimism! The worst that can happen here is that the PR screws up downloading all pre-release software. Plan B would be to revert it, if it causes a catastrophic failure. (I'm not really expecting that to be necessary!)

At the moment I've been seeing also corrupt download messages for the pre-release package. It seems to be sporadic:

npm warn tarball tarball data for cypress@https://cdn.cypress.io/beta/npm/14.5.0/win32-x64/develop-ec252f8601d9cec4543085667c7e03ecdab8e82f/cypress.tgz (sha512-NbsyKOBy+XedwuTn0z8HUBhRo6uiSfUFK7+fO68tdC16Fa1QtGy/fbMey6K8YQUDyRa2UtVJhYFBsStrlPabXQ==) seems to be corrupted. Trying again.

Same for the latest pre-release based on 76eb083. The first time I tried it, I got a checksum error and the second time it worked. Don't quite know what's going on there!

@MikeMcC399 is it possible to add a unit test for this here?
