Cypress: Cypress Fails suddenly fails on Travis CI

[rwieruch]

Current behavior:

One day ago, Travis CI started to fail running my Cypress tests.

As you can see, only the README.md has changed with some markdown, but no implementation details or library updates (except for the Greenkeeper attempts to update libraries) are in the build history.

The stack trace on Travis CI:

> [email protected] cypress /home/travis/build/the-road-to-learn-react/react-testing-jest-enzyme
> cypress run
It looks like this is your first time using Cypress: 3.4.0

[16:55:58]  Verifying Cypress can run /home/travis/.cache/Cypress/3.4.0/Cypress [failed]
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.

I have "cypress": "^3.4.0", as devDependencies and my test script looks like the following:

  "scripts": {
    "start": "webpack-dev-server --config ./webpack.config.js --mode development",
    "test": "jest --config ./jest.config.json",
    "test:watch": "npm run test -- --watch",
    "test:cypress": "start-server-and-test start http://localhost:8080 cypress",
    "cypress": "cypress run",
    "coveralls": "cat ./coverage/lcov.info | node node_modules/.bin/coveralls"
  },

Desired behavior:

Running Cypress Tests on Travis CI.

Steps to reproduce: (app code and test code)

Failing GitHub repository. The last commits haven't changed any libraries or source code.

Versions

Cypress 3.4.0

Travis CI has changed its underlying OS image, causing this problem. Luckily it is simple to fix, see https://docs.cypress.io/guides/guides/continuous-integration.html#Travis
