I thought I would fork and clone the D2 repo to my dev raspberry pi so I could poke around with the v-calendar request I made a few weeks ago, which appears to have hit a bit of a road block.

Following these instructions [Contributing | Node-RED Dashboard 2.0](https://dashboard.flowfuse.com/contributing/#installing-locally) I got to the `npm run build` command and received the following error message ` The Cypress App could not be installed. Your machine does not meet the operating system requirements.`

So I'm assuming that Cypress cannot be installed on the Pi, and my efforts have also hit a road block. Is this a correct assumption?

Cheers  
Bob

1. What version of Node are you running?
  1. [The Cypress App could not be downloaded (Can't install via NPM I on WINDOWS 2012) · Issue #6315 · cypress-io/cypress · GitHub](https://github.com/cypress-io/cypress/issues/6315) seems to suggest a use had this with Node 16, 18 but not Node 20
  2. Other comments are "are you behind a proxy" or "have network issues"?
  3. NOTE: I am using Node 18 on a Win PC and cypress installs fines

2. cypress is really only for testing so I am surprised the error came up at the `npm run build` step - most curious.

If using a Pi is not the issue then at least I can look in another direction. I'll try again tomorrow.

I am doing contributions for dashboard D2 on a Raspberry 4 all the time without problems. Cannot remember that I have had any issues related to Cypress.

BTW nice to hear that you want to try to contribute 👍

Is this maybe a hint (32bit)?

Might be relevant. For me it works fine on aarch64 ...

Yes, indeed, good pick up. I spun up a 64 bit Pi OS (and aside from JS heap issues which I solved) I now have a working clone of the Dashboard.

Thanks @bakman2
