In my case cypress had trouble accessing /root/.cache/Cypress upon npm install:

EACCES: permission denied, mkdir '/root/.cache/Cypress'

I found a relevant issue and ended up setting a custom cache dir:

export CYPRESS_CACHE_FOLDER=/app/.cache
npm install

Try using yarn package manager or downgrading npm to version 7. For me it worked correctly.

I'm using Jenkins in an alpine linux container with node 16.

    stage('Prepare-build') {
    steps {
        sh 'node --version'
        sh 'npm --version'
        sh 'ls -p'
        sh 'git config --global --add safe.directory "*"'
        sh 'yarn install'
    }
}

The error I was getting is the following:

npm ERR! code 1
npm ERR! path /home/jenkins/agent/workspace/project/app/project-web-manager/node_modules/cypress
npm ERR! command failed
npm ERR! command sh /tmp/postinstall-716e113e.sh

In my same case export the environment variable cypress cache folder did not work as expected, the error was even made mentioned above.

export CYPRESS_CACHE_FOLDER="/home/jenkins/agent/workspace/project/app/.cache"

After clearing my Cypress cache folder with cypress clear cache I ran into this issue as well.

This is what I did:

sudo rm -rf the Cypress folder in your .cache directory
For me I also deleted the Cypress folder in node_modules
Cleaned cache with npm cache clean --force
Installed Cypress with npm install cypress --save-dev

Hope this helps!

In my case I had issues running Cypress on Mac

An unexpected error occurred while verifying the Cypress executable.  

----------

Error: EACCES: permission denied, open '/Users/me/Library/Caches/Cypress/9.7.0/binary_state.json'

----------

Platform: darwin-x64 (22.2.0)
Cypress Version: 9.7.0

The easiest think to do is to locate the folder within Finder app, and for both "Cypress" and "9.7.0" folder and adjust the permissions for "everyone" and "staff" to "Read & Write".

Note: You must click on the lock icon and use your mac admin/system password to change the permissions.
