I have a Nodered install for tests in which I was testing dashboard 2.0.
I tried to upgrade to version 1.1.0 using the "manage palette" menu, and pressed the "update" button. I had a success report and a warning message to restart Nodered, which I did.
After restart I had some error messages about unknown nodes (previously used dashboard 2.0 nodes).
Checking the palette, dashboard 2.0 was no more installed.
I then tried to reinstall, but I got this error message in the log:
I did a nodered restart and browser refresh.
In the palette, the nodes tab shows nothing, whereas in the install tab I can still flnd @flowfuse/node-red-dashboard. I can press the install button but here is what I got after trying to install :
izno@lepotato:~/.node-red$ npm i @flowfuse/node-red-dashboard
up to date, audited 241 packages in 7s
33 packages are looking for funding
run `npm fund` for details
found 0 vulnerabilities
after nodered restart, it was still not installed in the palette.
So I checked the directory .node-red/node_modules/@flowfuse/node-red-dashboard and the directory existed.
I made a manual npm uninstall, then node-red-restart then npm install again.
After node-red-restart, now the nodes show up in the editor !
Problem solved, but don't know why
Maybe something conflicted during the initial "update" process.
