and I get the message
gideon@raspberrypi:~ $ npm i node-red-dashboard
npm ERR! code FETCH_ERROR
npm ERR! errno FETCH_ERROR
npm ERR! invalid json response body at https://registry.npmjs.org/engine.io reason: Unexpected end of JSON input

npm ERR! A complete log of this run can be found in:
npm ERR! /home/gideon/.npm/_logs/2022-08-08T10_15_46_467Z-debug.log

any one can help me?

Hi can you consider updating the npm and try?

3

How did you install node red? Did you use the recommended script in the node red docs?

4

didn't help

5

witch script?
I try to install the dashboard from the NR and from shell and it is the same

Please check if this could be of any help -- https://discourse.nodered.org/t/problem-installing-node-red-dashboard/26192

Google for
Install node red pi
And go to the one on nodered.org

From the error you posted. a) you aren’t in the user node-red directory. Usually ~/.node-red. b) it seems to be failing to get the package from the npm site. Is your internet connection stable ? Not via a proxy etc ?

Thanks
the internet connection is stable but weak.
I try to install from the NR > manage > palette so I think the directory is ok

I try this to
ideon@raspberrypi:/usr/lib $ npm install node-red-dashboard
npm WARN registry Unexpected warning for https://registry.npmjs.org/: Miscellaneous Warning EAI_AGAIN: request to https://registry.npmjs.org/node-red-dashboard failed, reason: getaddrinfo EAI_AGAIN registry.npmjs.org

You have shown us
gideon@raspberrypi:~ $ npm i node-red-dashboard
and
gideon@raspberrypi:/usr/lib $ npm install node-red-dashboard

Neither of those are correct, it should be

cd ~/.node-red
npm install node-red-dashboard

But that doesn't explain EAI_AGAIN or FETCH_ERROR

thanks that the err I get now

gideon@raspberrypi:~ $ cd ~/.node-red
npm install node-red-dashboard

npm ERR! errno FETCH_ERROR

If you do a google search on npm ERR! code FETCH_ERROR you will find that this is generally happens when your network is not stable and cannot connect to the NPM servers properly.
Here is a website with directions on what to do to fix the issue:
