Try

yarn cypress install --force

If that does not work, can you provide your package.json and .yarnrc.yml files?

[slikts]

The same happens in a newly created package as well (with yarn init or npm init), so there's nothing special about my Yarn config or package.json.

❯ yarn --version
3.6.0-git.20230603.hash-3c8237cb

❯ node --version
v20.5.0

❯ yarn init -y
{
  name: 'cypress-test'
}

@slikts

Thanks for your logs. Here's what happened why I ran this on Ubuntu 22.04.2 LTS:

yarn --version
3.6.0

node --version
v20.5.0

yarn init -y
{
  name: 'cypress-test',
  packageManager: 'yarn@3.6.0'
}

yarn add cypress

• Which Linux are you using?
• Do you know why your yarn --version is showing a different text 3.6.0-git.20230603.hash-3c8237cb to mine 3.6.0?
• What does your .yarnrc.yml look like?

@slikts

Please check that you are using an official release of Yarn Modern:

yarn set version 3.6.0

or

yarn set version berry

[slikts]

Same issue happens with npm:

❯ npm i cypress
npm ERR! code 1
npm ERR! path /c/work/cypress-test2/node_modules/cypress
npm ERR! command failed
npm ERR! command sh -c node index.js --exec install
npm ERR! /home/slikts/.cache/Cypress/12.17.2/Cypress/resources/app/package.json: Unexpected end of JSON input

npm ERR! A complete log of this run can be found in: /home/slikts/.npm/_logs/2023-07-26T06_44_59_083Z-debug-0.log

I fixed it by doing this:

rm -rf ~/.cache/Cypress

@slikts

Thanks for posting how you solved the corrupt cache.

yarn cypress cache clear

may also have solved this issue.
