After upgrading to 3.2.0 specs won't run on chrome or chromium only on Electron browser

[acyuta108]

Current behavior:

Can't start server
EACCES: permission denied, unlink '/home/acyuta/.config/Cypress/cy/production/browsers/chrome/interactive/CypressExtension/background.js'  

Debug output:

$ DEBUG=cypress:* 
cypress:server:events send error: { Error: EACCES: permission denied, unlink '/home/acyuta/.config/Cypress/cy/production/browsers/chrome/interactive/CypressExtension/background.js'   cause: { Error: EACCES: permission denied, unlink '/home/acyuta/.config/Cypress/cy/production/browsers/chrome/interactive/CypressExtension/background.js'   errno: -13, code: 'EACCES', syscall: 'unlink', path: '/home/acyuta/.config/Cypress/cy/production/browsers/chrome/interactive/CypressExtension/background.js' }, isOperational: true, errno: -13, code: 'EACCES', syscall: 'unlink', path: '/home/acyuta/.config/Cypress/cy/production/browsers/chrome/interactive/CypressExtension/background.js' } +21ms

Desired behavior:

Browser should open and run selected spec(s)

Steps to reproduce: (app code and test code)

$(npm bin)/cypress open # which currently points to ~/.cache/Cypress/3.2.0/Cypress/Cypress
Click on any spec
Error shows on app screen

If I clear (rm -rf ~/.config/Cypress) the config folder it gets recreated on next run, but error persists.
If I switch to Electron browser, specs run as expected.
If I run specs from the cli ($(npm bin)/cypress run), specs run as expected.

Versions

Cypress 3.2.0
Chrome and Chromium 72
Linux NixOS 4.14.98

The only change I can think of from 3.2.0 with the extension was us adding an extension id

The Cypress Chrome extension now has a static ID of caljajdfkjjjdehjdoimjkkakekklcck. This allows Cypress to be added to extension whitelists for those working under corporate policies that prohibit extensions. Addresses #3673, #1239 and #2494

Had you at some point set up some permissions around allowing Cypress as a Chrome extension within your company or anything in the past?

[acyuta108]

I did read that in the CHANGELOG. I am pretty certain that's not the case. Another user reported the same issue to me via Nixos/nixpkgs repo.
I'll dig in to see if there is anything else we need to do in order to get Cypress 3.2.0 working on NixOS.

I confirm this persist in 3.4.0.

[acSpock]

Getting this same error in 3.4.0 and in 3.3.1

[ArshadIram]

I am also able to see this error. I have latest cypress version and my chrome version is 75.

[ArshadIram]

This issue has fixed for me it was only happends for chrome 75 version. Now i have chrome 76 version

[mmahut]

Having the same problem with chrome 76.

[ArshadIram]

try used sudo before using cypress UI interface

[DylanVann]

I have encountered this issue. Using sudo yarn cypress open works though.

[kliu128]

I believe the problem is that all the cypress files in the NixOS store are readonly. Doing chmod 777 /nix/store/...-cypress-3.4.1/opt fixes the problem, but is obviously a major hack (you have to remount the nix store read-write).

This PR should fix that: #5579
