I can't open Cypress on Mac: Cypress not found

Question

I've checked through the answers on S.O and so far none have worked for me.

I put my question in a video. Watch it here

What went wrong? It was working fine yesterday?

What I've done so far:

Re installed cypress

tried to open with : .node_modules\.bin\cypress open

then tried: npx cypress open

Got the following message

No version of Cypress is installed in: /Users/jacquelinegeorge/Library/Caches/Cypress/3.4.0/Cypress.app

Please reinstall Cypress by running: cypress install

----------

Cypress executable not found at: /Users/my_name/Library/Caches/Cypress/3.4.0/Cypress.app/Contents/MacOS/Cypress

Platform: darwin (18.7.0)
Cypress Version: 3.4.0

Answer 1

I tried the following command on my Mac and it worked:
