`The futex facility returned an unexpected error code` tutorial install for Cypress 9 on WSL 2 #21075

bananabrann · 2022-04-13T21:52:27Z

Current behavior

When installing Cypress on WSL 2, node_modules/.bin/cypress open fails, and Cypress is not usable.

I realize that it's probably me and not Cypress, but I am at a loss because I have spent two hours meticulously combing through the tutorial config values making sure they're accurate. (Every item listed in the "Other" section on this issue)

Tutorials followed: https://docs.cypress.io/guides/getting-started/installing-cypress#Windows-Subsystem-for-Linux and https://nickymeuleman.netlify.app/blog/gui-on-wsl2-cypress with fresh projects each time.

Including DEBUG=cypress:* produces no additional logs. Edit below

From the project root with package.json, running node_modules/.bin/cypress open:

The futex facility returned an unexpected error code.
The Test Runner unexpectedly exited via a exit event with signal SIGABRT

Everything from the WSL2 installation guide appears to be working in as-expected condition.

This is occuring not in any integrated terminal in a code editor. This is just the regular, default terminal for WSL2.
Windows firewall inbound allowing everything for VcxSrv.exe
Echoing DISPLAY produces an IP address as expected.
WSL2 has been restarted, and ~/.bashrc is properly sourced (Numbers '1' to '7' is just to hide my IP. The 0.0 is real.)

lee@DESKTOP-BHC5NFB ~/$ echo $DISPLAY

/etc/sudoers.d/dbus appears to be set up correctly.
Everything from the tutorial has been added ~/.bashrc
In Windows' command prompt (on my native machine, completely outside of WSL2), wsl -l -v says I am indeed running WSL

The text was updated successfully, but these errors were encountered:

Taking shots in the dark at this point to hopefully provide some more clues:

Followed the suggestion mentioned in Presence of DISPLAY env var causes "Cypress failed to start" #4034 and Dependencies missing while using your docker image #1556 and unset DISPLAY variable.

[2087:0413/185241.030517:ERROR:bus.cc(392)] Failed to connect to the bus: Could not parse server address: Unknown address type (examples of valid types are "tcp" and on UNIX "unix")
[2259:0413/185241.126059:ERROR:gpu_init.cc(453)] Passthrough is not supported, GL is swiftshader, ANGLE is

So I guess that part was correct, I can definitively cross issues with the IP off the list of culprits.

I did a full network reset and rebooted, no changes.

bananabrann · 2022-04-14T13:02:30Z

(Hopefully) more clues:

Using Next.js's example app for Cypress yields the same result.

npx create-next-app@latest --example with-cypress mycoolapp

Adding an -ac flag to the properties of VcXsrc.exe does not work.

bananabrann · 2022-04-14T13:23:33Z

None of the steps here work as well, issue seemingly is only with Cypress:

protoEvangelion · 2022-04-27T22:30:20Z

@bananabrann I'm also experiencing this but on mac + docker!

bananabrann · 2022-05-03T14:45:40Z

@rdotg Dang. Bummer to see others with it too, but thanks for letting me know I'm not the only one.

My current work around is not to use Cypress on Windows. If I want to do anything with my tests/Cypress, I switch to my laptop (Ubuntu 20). 😕

fergarcia5 · 2022-09-09T16:43:01Z

any news about this issue?

github-actions · 2023-05-12T17:58:13Z

This issue has not had any activity in 180 days. Cypress evolves quickly and the reported behavior should be tested on the latest version of Cypress to verify the behavior is still occurring. It will be closed in 14 days if no updates are provided.

bananabrann · 2023-05-13T19:56:35Z

Issue is still present, I never could get it to work 😔 Our team moved to other testing software for one of our projects

nagash77 · 2023-05-15T12:53:09Z

@bananabrann Cypress does not support WSL or WSL 2 at this time. I am going to close this issue.

stoikerty · 2023-08-15T15:50:28Z

Try running export DISPLAY=:0 and running npx cypress open again. Tricky one to figure out, it worked for me.

I found the solution here: electron/electron#24211 (comment)
