Question: I am getting this error 'Cypress executable not found at: /root/.cache/Cypress/3.8.3/Cypress/Cypress' when the cypress command 'npx cypress run -P projects/demoProject-cypress' is run on docker at cloud. This is a command written in jenkins to run before deployment. I have tried wait-on but it is not useful. This is a angular project on npm.

Help!

Answer: 
your npx command trying to run from the root. Try using from nodemodules of the current project. 

```
/node_modules/.bin/cypress run

```

This will open and run the cypress. Let me know still you are facing issues.
Perhaps late answer, but still:

I had this errors mostly because of the version mismatch between docker image specified in Dockerfile or docker run command: `cypress/included:8.4.0` and cypress version in project package.json which was `"cypress": "8.3.0"`
