Cannot run cypress with a fresh yarn pnp install

[saudpunjwani101]

I'm trying to setup Cypress with jest adapter and testing-library/cypress but I'm encountering an issue as I'm using Yarn Pnp. Here I tried to do it in a fresh project.

mkdir test-cypress && cd test-cypress
yarn init
yarn add react react-dom vite
yarn add cypress --dev
yarn run cypress open

And I get an error,

Error: Your application tried to access @opentelemetry/resources, but it isn't declared in your dependencies; this make
s the require call ambiguous and unsound.

Required package: @opentelemetry/resources (via "@opentelemetry/resources")
Required by: /Users/Saud/Library/Caches/Cypress/12.17.1/Cypress.app/Contents/Resources/app/packages/telemetry/dist/

My package.json file,

{ "name": "new-cypress", "packageManager": "yarn@3.3.0", "dependencies": { "react": "^18.2.0", "react-dom": "^18.2.0", "vite": "^4.4.2" }, "devDependencies": { "cypress": "12.17.1" } }

If I do it via npm, it works fine. The problem is somehow related to Yarn pnp. Note that I've tried downgrading cypress to v10 and v9. The same problem occurs, just that in v10 I get this same error but for a different library like "lodash" and in v9 I get this error for library "graceful"

Try loose mode. e.g. By setting YARN_PNP_MODE=loose

Alternatively try setting nodeLinker: pnpm in your .yarnrc.yml and removing all the pnp files. This will make your setup not fully Zero Install as it will have to unpack all the zip files from the cache or download them again but it does produce a sufficiently normal node_modules to keep Cypress happy.

did this fix your issue? I am getting the same error.

Getting the same error here on Win11... I've been needing to set nodeLinker: node-modules in my .yarnrc.yml file temporarily as a workaround to this issue
