Cypress: Gtk-WARNING **: cannot open display: when cypress is first run from CLI

[tomato41]

Current behavior:

After directly downloading from the website and running Cypress verify or Cypress version, this message is displayed: Gtk-WARNING **: cannot open display:

Desired behavior:

It seems like cypress is trying to open a GUI, but this should not be necessary. We want to be able to run it via CLI.

Steps to reproduce: (app code and test code)

1. Direct download from cypress.io
2. Running Cypress verify

Versions

Cypress : via direct download(should be the latest version)
OS: Debian GNU/Linux 9

Hey @tomato41, can you paste the DEBUG logs that are printed during cypress verify please? Thanks!

[tomato41]

Hey @jennifer-shehane, I get the same message when I try to run it with debug turned on.

[jennifer-shehane]

@tomato41 Can you print the DEBUG logs here in the issue for us to look at please?

[tomato41]

I literally only get (Cypress:57487): Gtk-WARNING **: cannot open display: when I run it with debug turned on. I don't get any logs.

Unfortunately we have to close this issue as there is not enough information to reproduce the problem. This does not mean that your issue is not happening - it just means that we do not have a path to move forward.

Please comment in this issue with a reproducible example and we will reopen the issue. 🙏

@tomato41 FYI I got the same issue than you by launching the docker container.
And "xhost +" solved my issue. Then I could run Cypress.

[JacekWalczak92]

For me works:
-> change display to 0:0:
export DISPLAY=0:0
-> then:
xhost +
-> set up a display to proper one:
export DISPLAY=$IP:0
-> and launch docker container :)|

I have the same issue inside a Docker container (running on a Mac as the host) and via Kubernetes on Ubuntu. On my mac as the host I do not have xhost command.

Anyone who can help me?

This is usually caused by a missing library or dependency.

The error below should indicate which dependency is missing.

If you are using Docker, we provide containers with all required dependencies installed.

(Cypress:1699): Gtk-WARNING **: 15:32:48.530: cannot open display:

Is there a missing dependency from the docs what we miss related to Gtk?

@PMK try Cypress 3.8.3, there was a fix related to this
