I'm using the Cypress code-coverage and instrument-cra plugins. This works just fine when run locally on my own machine, but when run through CircleCI I get:
CypressError: cy.task('coverageReport') failed with the following error:
> Error: Command failed with ENOENT: nyc report --report-dir ./coverage --temp-dir /root/app/.nyc_output --reporter=lcov --reporter=clover --reporter=json
spawn nyc ENOENT
It's not clear which file it complains about. I've verified that /root/app/.nyc_output exists and contains coverage data.
I've enabled debug logging in Cypress and got:
code-coverage parsed sent coverage +0ms
code-coverage created folder /root/app/.nyc_output for output coverage +1ms
code-coverage wrote coverage file /root/app/.nyc_output/out.json +17ms
cypress:server:plugins:child execute plugin event: task ({ eventId: 2, invocationId: 'inv11' }) +100ms
code-coverage saving coverage report using command: "nyc report --report-dir ./coverage --temp-dir /root/app/.nyc_output --reporter=lcov --reporter=clover --reporter=json" +68ms
code-coverage current working directory is /root/app +0ms
The full run is available at https://circleci.com/gh/magjac/graphviz-visual-editor/114
I've followed this guide to set things up.
This is my CircleCI config.yaml (with lots of horrible debug and a workaround):

EDIT: It's the nyc command that is not found. Adding `env PATH="$PATH:./node_modules/.bin" before Cypress invocation solves the problem. Do I really have to use this or is there a better way?
EDIT 2: A better workaround is to use npx cypress run
which sets the path to node_modules/.bin automatically. Perhaps this is the real solution?
