Getting error "EACCES: permission denied" when i install cypress

Question

When i try to install cypress using this commnad:

sudo npm install cypress

or

sudo npm install -g cypress

It is giving me this error:

Error: EACCES: permission denied, open '/Users/humac/node_modules/cypress/cypress.zip'

Answer 1

Workaround: sudo npm install --unsafe-perm=true --allow-root cypress

Answer 2

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
