@baris Thanks a lot, it's working now ^_^
I will wait for the RSS plugin

@julian said in Problem with a saas instance when installing a plugin (spawn yarn NOENT):

@Lmame Good to go, can you try again?

We changed the way we deployed NodeBB Instances so that npm was used again (we were initially using yarn, but we just removed it completely now)

Thanks a lot!
I managed to install a 3 or 4 plugins from the "trending" tab (without hitting build and restart, I activated the first one, but did not build / restart, I was waiting to install all of them to activate them and then doing a build and restart), but then when I tried to install one from the "find" tab (around the last ones, I can't remember the name), I had this error:

Then when I tried to navigate back to the plugins, the list was empty:

I saw this in the logs:

When I tried to just restart, the server seems down now, and is showing a 502 page.

I guess I killed my instance

Hi
I spinned a trial community and I was playing with it. When trying to deploy a plugin (any, like iframely), I constantly have this error (spawn yarn NOENT):

In the console log I see:

2023-09-15T04:24:55.234Z [4567/2178] - error: admin.plugins.toggleInstall
Error: spawn yarn ENOENT
    at ChildProcess._handle.onexit (node:internal/child_process:283:19)
    at onErrorNT (node:internal/child_process:476:16)
    at process.processTicksAndRejections (node:internal/process/task_queues:82:21)

It's almost as for some reason it's trying to use yarn rather than npm to deploy the plugin (?)
