Module cannot be found when running in Docker

[sbattistin]

When trying to run the tests in a Docker container, the module cypress-plugin-retries cannot be found and the tests fail.

The output from the tests is the following.

Fontconfig warning: "/etc/fonts/fonts.conf", line 100: unknown element "blank",

Oops...we found an error preparing this test file:,

  /cypress-tests/cypress/support/index.js,

The error was:,

Error: Cannot find module 'cypress-plugin-retries' from '/cypress-tests/cypress/support',


This occurred while Cypress was compiling and bundling your test code. This is usually caused by:,

- A missing file or dependency,
- A syntax error in the file or one of its dependencies,

Fix the error in your code and re-run your tests.,

I tried both to install the module globally and with npm install from the package.json file but the error still shows up.

I need this to be able to run the cypress tests with Jenkins using Docker.

I attached a simple version with all necessary files to reproduce the problem.

@sbattistin Hey Stefano,

I'm getting the same error you had when running my CI build. How did you fix it?
