@cbohatka-cardinal This is 100% a system permission issue. My guess is that you’ve installed node or npm with sudo. Did any of you install node with nvm? You could try that. It appears you installed a system wide node, which is not recommended.

The error EACCES is coming from node when we try to access the zip that we just downloaded. I don’t believe there’s anything Cypress can do about it - the binary app and CLI is downloaded 10,000+ times a day on all 3 operating systems so I don’t think there’s anything that’s on our end.

You can try running DEBUG=cypress:* npm install cypress to reinstall the binary and see what happens.

You can also try using version 3.x.x of Cypress since we changed how the binary is cached and installed. I’m going to close this issue as there’s no way we can reproduce this since it’s too specific to your systems.
