Dependencies missing while using your docker image

Current behavior:

I am trying to integrate cypress into our deployment process and I am using one of the your docker images for that (base:8 also tried a chrome one) It runs perfectly on my laptop but when i am deploying to the server it gives this error

It looks like this is your first time using Cypress: 2.1.0

[21:26:18]  Verifying Cypress can run /usr/src/app/node_modules/cypress/dist/Cypress [started]
[21:26:19]  Verifying Cypress can run /usr/src/app/node_modules/cypress/dist/Cypress [failed]
[21:26:19] → Cypress failed to start.

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.

How to reproduce:

I am not sure maybe try to run it in a container on a remote server

I’m finally able to resolve my issue and now Cypress is working fine for me.

Following environment variable was being set DISPLAY=:1.5

Unsetting this variable solved my problem. I hope this help someone else as well.

You can verify if you have value set in DISPLAY, by running the following command: echo $DISPLAY

Please try unsetting the NODE_OPTIONS environment variable if you have this set - as this causes Cypress to crash. This is due to an Electron bug prior to version 2.0.3, where having NODE_OPTIONS set causes either a failure or arguments to be ignored. https://github.com/electron/electron/issues/12695#issuecomment-385826834

To see all environment variables currently set

MacOS / Linux

printenv

Windows

SET

To unset NODE_OPTIONS environment variable

MacOS / Linux

unset NODE_OPTIONS # this is not the same as export NODE_OPTIONS=

Windows

set NODE_OPTIONS=

We have open issues for this being fixed that you can follow here:

• NODE_OPTIONS should not exit 0: https://github.com/cypress-io/cypress/issues/1676
• Electron update: https://github.com/cypress-io/cypress/issues/3568
• Version ~4.0~ 5.0 Release: https://github.com/cypress-io/cypress/issues/2840
