circleci orb issues/questions

[courtneymclark1]

I have a feeling I am not doing something correctly but can't seem to figure it out. Any help would be really appreciated. I trying to use cypress orbs for circleci for my cypress and percy scripts but I am running into an error during install with my cypress/run job.
I do have a package.json and package-lock.json in this project.

Error in my circleci build:

if [[ ! -z "" ]]; then
  echo "Installing using custom command"
  echo ""
  
elif [ "false" = "true" ]; then
  echo "Installing using Yarn"
  yarn install --frozen-lockfile
elif [ ! -e ./package-lock.json ]; then
  echo "The Cypress orb uses 'npm ci' to install 'node_modules', which requires a 'package-lock.json'."
  echo "A 'package-lock.json' file was not found. Please run 'npm install' in your project,"
  echo "and commit 'package-lock.json' to your repo."
  exit 1
else
  echo "Installing dependencies using NPM ci"
  npm ci
fi

**my current circleci config:**
version: 2.1
orbs:
  cypress: cypress-io/cypress@1
  percy: percy/[email protected]
workflows:
  build:
    jobs:
      - cypress/run:
          store_artifacts: true
          working_directory: name-of-working-directoy

Thanks in advance!

I think this is post-install script executed by the @percy/core NPM module. I think this question is better opened in the Percy repo, probably they require Ruby installed on the machine, which the Cypress default executor does not?

oh, thank you! That actually helps point me in the right direction!
