I'm trying to download and install Cypress within GitLab CI runner and getting this error output:

The cypress npm package is installed, but the Cypress binary is missing.
We expected the binary to be installed here: /root/.cache/Cypress/4.8.0/Cypress/Cypress
Reasons it may be missing:
- You're caching 'node_modules' but are not caching this path: /root/.cache/Cypress
- You ran 'npm install' at an earlier build step but did not persist: /root/.cache/Cypress
Properly caching the binary will fix this error and avoid downloading and unzipping Cypress.
Alternatively, you can run 'cypress install' to download the binary again.

I ran the suggested command cypress install but it didn't help. Next it says You're caching 'node_modules' but are not caching this path: /root/.cache/Cypress I don't understand how you can cache the modules and leave out the path to it. Next is You ran 'npm install' at an earlier build step but did not persist I did have npm install in earlier builds so I replaced it with npm ci as it's recommended in Cypress official docs in such cases.

No resolution though.

Here are relevant lines where the error occurs:

inside of Dockerfile:

COPY package.json /usr/src/app/package.json
COPY package-lock.json /usr/src/app/package-lock.json
RUN npm ci

inside the test runner:

docker-compose -f docker-compose-prod.yml up -d --build
./node_modules/.bin/cypress run --config baseUrl=http://localhost

inside the package.json:

{
  "name": "flask-on-docker",
  "dependencies": {
    "cypress": "^4.8.0"
  }
}

Can anyone point me in a right direction ?

npm cypress gitlab-ci docker

You probably are running npm install and cypress run in two different stages. In this case, cypress cache could not be persisted, So it is recommended to use CYPRESS_CACHE_FOLDER option while running install and as well as cypress run/open. The command will looks like this,

CYPRESS_CACHE_FOLDER=./tmp/Cypress yarn install

CYPRESS_CACHE_FOLDER=./tmp/Cypress npx cy run [--params]

yarn cypress install --force before running of tests worked for me

I had the same problem I run this code to grant jenkins user to be the owner of my cypress project folder and after that everything was ok.

sudo chown -R jenkins: /your cypress project path/
